Default password

A default password is a preconfigured authentication credential, typically a username and password pair, set by manufacturers for devices, software, or systems to facilitate initial setup, testing, or factory reset procedures.^[1] These credentials are often standardized across product lines, such as "admin" as the username with "password" or "1234" as the password, to streamline manufacturing and deployment processes without requiring custom user management interfaces from the outset.^[2] Default passwords appear in a wide range of technologies, including routers, firewalls, industrial control systems (ICS), embedded devices, and Internet of Things (IoT) equipment, where they serve as temporary placeholders until users customize them.^[1] While convenient for initial access, unchanged default passwords pose significant cybersecurity risks by providing attackers with predictable entry points into systems.^[3] These credentials are easily discoverable through product documentation, online databases, or vulnerability scanning tools like Shodan, enabling unauthorized access, privilege escalation, and potential data breaches.^[3] In critical infrastructure, such as ICS and supervisory control and data acquisition (SCADA) systems, exploitation of defaults has led to real-world incidents, including botnet recruitment and disruptions like false emergency alert warnings. More recently, as of 2025, default credentials in building management systems like the Hirsch Enterphone MESH have been identified as vulnerabilities potentially exposing personal information in apartment buildings across Canada and the United States.^[3]^[4] The OWASP Foundation identifies default credentials as a top infrastructure security risk, as they facilitate brute-force and dictionary attacks, compromising authentication integrity across networks.^[5] To mitigate these vulnerabilities, security best practices emphasize immediate replacement of default passwords with strong, unique alternatives upon device installation or deployment.^[3] Organizations are advised to enforce password complexity policies—requiring at least eight characters with a mix of uppercase, lowercase, numbers, and symbols—while implementing multi-factor authentication (MFA) and restricting remote access to trusted networks via VPNs or SSH.^[5] Manufacturers can further reduce risks by designing products that prohibit defaults in production, generate unique credentials based on device identifiers like MAC addresses, or mandate changes during first login.^[2] Regular audits and employee training on credential hygiene remain essential to prevent oversight in diverse environments, from consumer gadgets to enterprise infrastructure.^[1]

Definition and Purpose

Definition

A default password is a pre-configured authentication credential, typically a simple username and password pair such as "admin" with "admin" or "password," that manufacturers or developers set on devices, software, or systems to facilitate initial access during setup or after a factory reset.^[1]^[2] These credentials are often identical across multiple units from the same vendor, making them publicly documented and easily discoverable through product manuals or online resources.^[3] Unlike temporary or one-time passwords, which are designed to expire after a single use or short duration, default passwords persist indefinitely until explicitly changed by the user or administrator, remaining active as a standard access method.^[5]^[2] This persistence stems from their role in simplifying manufacturing and deployment processes, where customizing unique credentials for each unit would be impractical.^[2] Default passwords enable rapid initial configuration and testing by providing immediate access without requiring prior user input, under the assumption that owners will replace them with secure alternatives to prevent unauthorized entry.^[3]^[1] However, unchanged defaults represent a significant security vulnerability, as attackers can exploit them to gain administrative control over systems.^[3] Typical formats include shared generic terms like "default" or "guest," numeric sequences such as "1234" or "0000," and even blank (empty) password fields in some configurations.^[1]^[6]^[7]

Historical Context and Evolution

In the 1970s and 1980s, default passwords emerged as a practical necessity for initial system access in mainframe computing environments, where complex setups required factory-set credentials for technicians and administrators. IBM's Time Sharing Option (TSO) under MVS operating systems, introduced in the early 1970s, included a standard default user ID of IBMUSER with the password SYS1 to facilitate first-time logons and system generation, after which users were required to change it for security.^[8]^[9] These defaults were designed for controlled enterprise environments, reflecting the era's focus on operational efficiency over widespread user authentication, as personal computing was nascent and mainframes dominated secure, multi-user operations. Early personal computers in the 1980s, such as the IBM PC, rarely featured built-in password systems at the hardware level, with authentication limited to application-specific defaults in business software to enable quick installations.^[10] The 1990s marked a significant evolution with the proliferation of consumer internet devices, as dial-up modems and early broadband routers entered households, prioritizing ease of setup amid growing home connectivity. Defaults like "admin" for both username and password became ubiquitous in devices from manufacturers such as Linksys, whose first wireless router launched in 2000, allowing non-expert users to configure networks without technical barriers.^[11]^[12] This standardization simplified deployment for the emerging consumer market but introduced uniform vulnerabilities, as vendors like Netgear and 3Com adopted similar credentials across product lines to streamline manufacturing and support.^[13] By the 2000s, escalating cyber threats, including widespread worm attacks and unauthorized access incidents, prompted industry shifts toward enhanced default configurations in networking hardware. Post-2003, following the Wi-Fi Alliance's introduction of WPA security to replace vulnerable WEP, router manufacturers began implementing randomized, device-specific pre-shared keys for Wi-Fi authentication, often printed on the hardware label to encourage immediate use without manual entry.^[14] This partial transition reduced reliance on universal defaults for wireless encryption, though admin interface passwords remained static in many models, reflecting a gradual move driven by standards bodies like the IEEE 802.11 working group.^[15] In modern trends as of 2025, the rise of Internet of Things (IoT) devices has accelerated the adoption of unique per-device default passwords, influenced by regulatory frameworks emphasizing data protection and supply chain security. The EU's General Data Protection Regulation (GDPR), effective 2018, mandates robust safeguards for personal data processing, indirectly compelling IoT vendors to eliminate shared credentials that could enable mass breaches. Complementing this, NIST's Special Publication 800-213 on IoT device cybersecurity, released in 2021, recommends unique authentication mechanisms to prevent default-based exploits in federal and commercial deployments.^[16] International standards like ETSI EN 303 645 (updated to version 3.1.2 in 2024) explicitly prohibit universal default passwords and require randomly generated unique per-device credentials for user and machine-to-machine authentication. In 2024, the EN 18031 series was published as harmonized standards under the EU's Radio Equipment Directive (RED), further enforcing these requirements for radio equipment including IoT devices.^[17]^[18] These developments foster an ecosystem-wide pivot toward inherent security in billions of connected devices.

Common Examples

In Hardware Devices

In networking equipment, default passwords are commonly set to facilitate initial setup, with many routers using "admin" as both username and password. For instance, the Linksys E2000 series defaulted to admin/admin for administrative access, while the E1000 used a blank username and admin password.^[11] Embedded systems within networking hardware often employ even simpler credentials, like root with a blank password, as seen in various industrial and router configurations to enable quick deployment.^[3] These patterns persist across vendors, prioritizing ease of installation over security from the factory. Internet of Things (IoT) and smart home devices frequently adopt similarly straightforward defaults to streamline user onboarding. IP cameras from manufacturers like Amcrest and Dahua, particularly pre-2016 models, used admin/admin as the standard login, allowing immediate connectivity without complex configuration.^[19] Smart locks and similar devices often default to numeric sequences such as 12345, reflecting a design choice for memorability during setup in consumer environments.^[20] Consumer electronics also rely on basic defaults for accessibility. Printers from HP, especially older LaserJet models, typically use admin with a blank password for embedded web server access, enabling users to configure settings out of the box.^[21] Set-top boxes and cable modems, such as certain Arris models, commonly default to user/user or admin/password combinations to support rapid integration into home networks.^[22] Hardware manufacturers favor these simple, memorable defaults to simplify manufacturing and end-user installation processes, reducing barriers for non-technical consumers.^[2] Such practices underscore the trade-off between usability and the potential for unauthorized access if not addressed.

In Software and Services

In operating systems, default passwords have historically been simple or absent to facilitate initial setup, but this practice has evolved with security awareness. For instance, in Windows XP (released in 2001 and supported until 2014), the built-in Administrator account was disabled by default in Professional editions, with no password assigned if not set during installation, allowing access via safe mode or recovery console if blank.^[23] Similarly, many Linux live distributions and minimal setups, such as Debian-based live CDs, often do not set a root password by default, effectively disabling direct root login and requiring sudo access from a standard user account created during installation.^[24] These defaults were tied to installation processes, prompting users to set passwords immediately, though many overlooked this step. In web and database services, default credentials frequently mirror administrative usernames with minimal or no passwords, exposing systems if unchanged. MySQL installations prior to version 5.7 commonly featured a root account with an empty password, enabling unrestricted access until secured via tools like mysql_secure_installation.^[25] phpMyAdmin, a popular web-based MySQL management tool, inherits these credentials, with root and no password as the standard default in many setups, though some bundled distributions used "admin" as both username and password for initial access.^[26] Such patterns persisted into the mid-2010s, as installation wizards assumed users would configure security post-setup. Cloud and SaaS platforms have shifted toward generated or retrievable defaults to balance usability and security, often avoiding fixed values. In Amazon Web Services (AWS) Lightsail instances, such as those running WordPress blueprints, the default administrator username is typically "admin," while the password is auto-generated and stored on the instance, accessible via SSH or the management console for retrieval during initial login.^[27] WordPress itself, when deployed via SaaS tools or plugins like those in Lightsail, uses "admin" as the default username, with a user-defined or generated password set during installation; however, certain plugins may include their own default keys, such as "password," if not overridden.^[28] Common patterns in software defaults include username-password pairs like "admin/admin" or "root/root," often embedded in installation scripts or configuration files to enable quick deployment. These are prevalent in web services and databases, where tools like phpMyAdmin or MySQL wizards prompt changes but default to weak values for convenience. According to the OWASP Web Security Testing Guide, testers routinely check for such credentials, including blanks or simple strings like "password," as they remain a standard misconfiguration vector.^[29] The Cybersecurity and Infrastructure Security Agency (CISA) highlights that default passwords in software and services contribute to numerous exploits annually, recommending their elimination in secure-by-design principles to mitigate risks in digital environments.^[30]

Security Risks

Vulnerabilities and Attack Vectors

Default passwords are highly predictable due to their standardized and simplistic nature, often consisting of common terms like "admin," "password," or "1234," which are well-documented in public lists and password dictionaries derived from historical data breaches such as the RockYou leak.^[5]^[31] These patterns enable attackers to employ targeted brute-force tools that systematically test known combinations, significantly reducing the time required to gain unauthorized access compared to random guessing.^[3] The use of universal default credentials across multiple devices and manufacturers amplifies risks by allowing large-scale reconnaissance and exploitation through internet-wide scans. Tools like Shodan can identify thousands of exposed systems—such as routers and IoT cameras—still configured with factory settings, making them low-hanging fruit for automated discovery and compromise.^[3]^[32] This shared vulnerability facilitates mass attacks, where a single exploited default can serve as an entry point to broader networks, as seen in scans revealing over 18,000 consumer IoT devices with insecure defaults.^[33] Key attack vectors exploiting default passwords include brute-force attacks, which iteratively attempt common credential pairs until success; credential stuffing, where leaked username-password combinations from one breach are tested against other services assuming reuse of defaults; and man-in-the-middle (MITM) intercepts on unsecured connections, where lack of encryption on initial authentication exposes credentials in transit.^[34]^[35]^[36] These methods are particularly effective against resource-constrained devices like IoT endpoints, which often lack rate-limiting or multi-factor protections, allowing rapid enumeration without detection.^[37] Quantitative assessments underscore the scale of these risks: weak or default passwords rank as the leading cause of IoT breaches, with surveys indicating that 86% of router administrators never change factory credentials, leaving millions of devices vulnerable globally.^[38]^[39] Additionally, cybersecurity analyses report that default credential exploitation accounts for over 5% of detected IoT attacks, contributing to widespread botnet formations and data exfiltration.^[40]

Notable Incidents and Impacts

One of the most significant incidents involving default passwords occurred with the Mirai botnet in 2016, where malware exploited unchanged factory credentials on Internet of Things (IoT) devices, such as IP cameras using combinations like "admin/12345." This allowed attackers to infect over 600,000 devices worldwide, forming a massive botnet that launched distributed denial-of-service (DDoS) attacks, including one that disrupted major internet services like Twitter, Netflix, and Reddit by overwhelming DNS provider Dyn. The event highlighted the scalability of default credential vulnerabilities in consumer hardware, leading to widespread service outages and prompting global calls for better IoT security.^[41] In 2017, a North American casino suffered network infiltration through a smart aquarium's connected thermometer, which retained its default login credentials, enabling hackers to access the internal network and exfiltrate a database of high-roller customer information. The attackers scanned for open ports and exploited the unsecured IoT device as an entry point, demonstrating how default passwords on peripheral sensors can compromise entire corporate infrastructures, resulting in potential financial and reputational damage to the organization. The 2021 Verkada breach exposed live video feeds from over 150,000 security cameras across hospitals, schools, police departments, and corporations, including sensitive locations like Tesla factories and women's health clinics, due in part to inadequate credential management that echoed default password risks. Hackers accessed the system via a superadmin account with exposed credentials, viewing real-time and archived footage, which violated user privacy on a massive scale and led to lawsuits alleging negligence in securing cloud-based IoT surveillance. In 2024, the U.S. Federal Trade Commission imposed penalties on Verkada for failing to implement reasonable security measures, underscoring regulatory consequences for such lapses.^[42] More recently, in late 2024, the Matrix botnet exploited misconfigurations and default credentials on IoT devices, including routers and cameras, to propagate Mirai variants and enable DDoS-for-hire services targeting regions like China and Japan. This supply chain-adjacent attack infected thousands of devices, amplifying threats to critical infrastructure and illustrating the ongoing persistence of default password exploitation in modern IoT ecosystems.^[43] In 2025, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued guidance on product security bad practices, explicitly urging manufacturers to eliminate default passwords to mitigate risks in operational technology systems, reflecting heightened regulatory focus on preventing exploitation in critical sectors.^[44] These incidents have contributed to broader impacts, including substantial financial losses, with IoT-related breaches often costing organizations between $5 million and $10 million due to downtime, remediation, and lost revenue. Privacy violations have affected millions, exposing personal data and footage without consent, while regulatory fines—such as those from the FTC—have enforced accountability, pushing industries toward mandatory credential changes. Collectively, default password failures exacerbate annual global cyber losses exceeding $10.5 trillion as of 2025, with IoT vulnerabilities playing a growing role in this economic toll.^[40]

Mitigation and Best Practices

User Actions

Upon acquiring a new device or software, users must prioritize changing default passwords immediately to prevent unauthorized access. This process typically begins by connecting to the device's administrative panel, often via a web interface accessed through the default IP address (e.g., 192.168.1.1 for routers) or a setup wizard that prompts for credentials during initial configuration.^[45]^[46] Once accessed, replace the factory-set password with a strong one comprising at least 16 characters, incorporating uppercase and lowercase letters, numbers, and symbols to enhance resistance against brute-force attacks.^[47] Password managers can automate generation and storage of these unique credentials, ensuring they are not reused across devices.^[48] To detect lingering default passwords on existing networks, individuals can employ free scanning tools that cross-reference device configurations against known vulnerabilities. SecLists, an open-source repository maintained for security testing, offers extensive lists of default credentials for thousands of hardware and software products, allowing manual or scripted verification. For home networks, tools like Avast Wi-Fi Inspector perform automated scans to identify devices using weak or unchanged default passwords, providing alerts and remediation steps without requiring advanced technical skills.^[49] Organizations, especially small businesses with limited IT resources, should establish mandatory protocols for default password replacement as part of employee onboarding and device deployment. These policies can include automated workflows, such as scripting bulk changes via tools like PowerShell or Ansible, to update credentials across multiple routers, IoT devices, or servers simultaneously, ensuring compliance from the outset.^[50] Regular audits, integrated into IT checklists, reinforce these measures by verifying that all new setups adhere to the policy.^[51] A frequent oversight is neglecting to update default passwords post-setup, often due to oversight during rushed installations, resulting in high non-compliance rates; for instance, a 2025 survey found that 81% of router users have not changed their admin passwords from factory defaults.^[52] Such inaction heightens exposure to exploits detailed in broader security risk analyses.

Industry Standards and Recommendations

Various industry standards and regulatory frameworks emphasize the elimination or immediate modification of default passwords to mitigate unauthorized access risks. The Payment Card Industry Data Security Standard (PCI DSS) version 4.0, under Requirement 2.2.4, mandates that organizations change vendor-supplied defaults, such as default passwords, for system components prior to allowing access.^[53] This provision builds on earlier versions, where Requirement 2 explicitly addressed secure configurations by prohibiting the use of default security parameters, recognizing their widespread exploitation by attackers.^[54] The International Organization for Standardization (ISO) in its ISO/IEC 27001:2022 standard, through Annex A Control 5.17 on authentication information, requires that default passwords be changed upon first system access to prevent unauthorized entry.^[55] This control promotes the allocation of authentication information in a manner that limits exposure, including enforcing user selection of strong passwords and periodic reviews, while integrating with broader information security management systems to address risks holistically.^[56] The Cybersecurity and Infrastructure Security Agency (CISA) issues targeted guidance urging manufacturers to eliminate default passwords entirely as part of secure-by-design principles.^[57] In its Secure by Design Alert, CISA recommends that technology providers take ownership of customer security outcomes by avoiding static defaults during product design and development, establishing organizational leadership to enforce these practices, and thereby reducing large-scale exploitation vulnerabilities.^[58] For end-users, CISA advises changing default credentials immediately upon device deployment and restricting access to authorized personnel only.^[47] The Open Web Application Security Project (OWASP) addresses default credentials within its Top 10 Infrastructure Security Risks, classifying insecure authentication methods—including unchanged defaults—as a critical vulnerability (ISR07).^[5] OWASP recommends changing default usernames and passwords upon installation, limiting device access to vetted users, and conducting employee education on the dangers of defaults to foster proactive security hygiene.^[5] The Center for Internet Security (CIS) Controls version 8, in Safeguard 4.2, stipulates that all default passwords on enterprise assets and software be changed to comply with the organization's unique password policy before deployment. This safeguard aligns with CIS's emphasis on controlled administrative privileges, ensuring defaults are replaced with strong, policy-adherent alternatives to prevent initial compromise vectors.^[59] These standards collectively prioritize proactive measures over reactive fixes, advocating for unique, strong authentication from the outset to enhance overall cybersecurity posture.
