What is token blacklisting and how does it work?
Token blacklisting is a security measure that involves maintaining a list of tokens that are no longer valid. When a token is blacklisted, it cannot be used for authentication or access to resources.
Why would a token be blacklisted?
Tokens can be blacklisted for various reasons, such as suspected fraud, user account compromise, or when a user logs out and wants to invalidate their session.
How is the blacklist updated?
The blacklist is typically updated in real-time by the authentication server, which can add tokens based on specific events or triggers.
Can users see if their token is blacklisted?
Generally, users are not notified directly if their token is blacklisted, but they may experience access issues when trying to use it.
What are the implications of token blacklisting for user experience?
Token blacklisting can enhance security but may lead to frustration for users if they are unaware of why their access is denied.
