signedOut

Signedout is a term used in computing to describe the state of a user who does not have an active authenticated session in a system. The phrase is commonly encountered in user interfaces as an indicator that the user is not currently signed in, and in codebases it may appear as a boolean flag or status variable such as signedOut.

In practice, signed-out status is achieved by performing a sign-out or log-out action. This typically involves invalidating authentication credentials on the server (for example, server-side sessions or tokens) and clearing local credentials on the client (such as cookies or stored tokens). After signing out, access to personal data and privileged features is restricted until the user signs in again. Many applications immediately redirect users to a login screen or home page with a message confirming the sign-out.

Different architectures handle sign-out in various ways. In token-based systems, sign-out may require revoking tokens and clearing refresh tokens to prevent misuse. In server-side session models, the session identifier is destroyed or marked invalid. Single sign-on (SSO) scenarios add complexity by signing out across multiple applications or devices, sometimes offering a global sign-out option.

Security considerations include ensuring complete invalidation of credentials, preventing session fixation, and protecting against cross-site request forgery during sign-out requests. From the user perspective, signed-out is a normal, reversible state, reflecting a preference for privacy or security by terminating access to a device or service.
