How do I handle authentication errors in my application?

Handling authentication errors typically involves checking the error type and providing user-friendly messages. What specific errors are you encountering?

I'm getting a 401 Unauthorized error when users try to access protected routes.

A 401 error usually means the user is not authenticated. You should redirect them to the login page and display a message explaining the issue.

What if the user is already logged in but still sees this error?

In that case, you might want to check if their session has expired or if their token is invalid. Implementing a refresh token mechanism can help.

Thanks! How can I implement a refresh token mechanism?

You can store a refresh token in a secure cookie and use it to obtain a new access token when the current one expires. Would you like more details on that?
