Token expiration is an important part of JWT (JSON Web Token) authentication in apps. Let's talk about why it matters.
JWTs help verify who users are. If a token doesn't expire, it could be good forever. This is a security risk.
For example, if someone steals a user's token, they could access the account until the token is canceled or runs out.
When we set an expiration time for the token, we reduce the chances of it being misused.
Imagine a user logs in and stays logged in for a long time. If a token doesn't expire, the user might not realize their account is at risk.
By setting a reasonable expiration time, like a few hours for access tokens, users need to log in again after some time. This helps keep their accounts safe and reminds them to stay aware of their security.
To make things easier for users while keeping their accounts safe, many apps use a two-token system.
This means they have access tokens that expire quickly and refresh tokens that let users get new access tokens.
For example, if an access token expires in one hour, the user can still stay logged in without having to enter their password again by using a refresh token to get a new access token.
In short, having token expiration in JWT authentication is crucial for keeping apps secure while providing a good user experience. It helps protect user accounts while also making it easy for them to stay logged in.
