Implementing Refresh Tokens
Develop a strategy for issuing and managing refresh tokens to securely extend user sessions without frequent re-authentication.
Why Short-Lived Access Tokens?
In modern security, Access Tokens (like JWTs) are typically designed to be short-lived. This means they expire quickly, often within minutes or a few hours.
Why? If an access token is stolen, its short lifespan limits the time an attacker can use it to impersonate a user. This reduces the window of vulnerability.
The User Experience Challenge
While short-lived access tokens are great for security, they can create a poor user experience. Imagine needing to log in every 15 minutes because your access token expired!
Users expect to stay logged in for extended periods without constant re-authentication. This is where Refresh Tokens come to the rescue.
