Token expiration is the practice of setting a predefined timeframe after which a token, such as a session token or access token, issued by an authentication system becomes invalid and unusable, thereby reducing the risk of unauthorized access to the system.
Token Expiration Definition: Token expiration is the practice of setting a predefined timeframe after which a token, such as a session token or access token, issued by an authentication system becomes invalid and unusable, thereby reducing the risk of unauthorized access to the system.
Token expiration refers to the predetermined period during which a token, often used for authentication and access control purposes, remains valid. Once this period expires, the token becomes invalid and users need to reauthenticate to obtain a new token for continued access. Token expiration is a critical security measure to mitigate the risks associated with unauthorized access and protect against potential threats like token theft or replay attacks. By setting an expiration timeframe for tokens, organizations can enhance the overall security of their systems and data.
