Initial authenticator content is the actual content of the authenticator, for example, the initial password. In contrast, the requirements about authenticator content include the minimum password length. Developers ship system components with factory default authentication credentials to allow for initial installation and configuration. Default authentication credentials are often well known, easily discoverable, and present a significant security risk.<br \/>\nSystems support authenticator management by organization-defined settings and restrictions for various authenticator characteristics including minimum password length, validation time window for time synchronous one-time tokens, and number of allowed rejections during the verification stage of biometric authentication. Authenticator management includes issuing and revoking, when no longer needed, authenticators for temporary access such as that required for remote maintenance. Device authenticators include certificates and passwords.<br \/>\nNIST SP 800-63-3 provides guidance on digital identities.<\/p>\n<p>Further Discussion<br \/>\nBefore a person or device is given system access, verify that the user or device is who or what it claims to be. This verification is called authentication. The most common way to verify identity is using a username and a hard-to-guess password.<br \/>\nSome devices ship with default usernames and passwords. Some devices ship with a default username (e.g., admin) and password. A default username and password must be immediately changed to something unique. Default passwords may be well known to the public, easily found in a search, or easy to guess, allowing an unauthorized person to access the system.<br
