About storing refresh tokens

Are refresh tokens permanent?

The Google Auth server issued Refresh tokens never expire — that’s the whole point of the refresh tokens. The refresh token will expire (or I should say become unauthorized) when the user revokes access to your application.

Can refresh tokens be reused?

This protection mechanism works regardless of whether the legitimate client or the malicious client is able to exchange refresh token 1 for a new token pair before the other. As soon as reuse is detected, all subsequent requests will be denied until the user re-authenticates.

What happens if refresh token is stolen?

If the refresh token can be stolen, then so can the access token. With such an access token, the attacker can start making API calls. To make matters even more complicated, access tokens are often self-contained JWT tokens. Such tokens contain all the information needed for the API to make security decisions.

Should I store token in Redis?

2 Answers. TLDR: If you want the capability to revoke the token at some point, yes, store it in something fast like Redis. One of the well documented drawbacks of using JWT is that there’s no simple way to revoke a token if for example a user needs to be logged out or the token has been compromised.

When should I remove refresh token?

Yes you should. Because after logout when the user will login a new access token with a new refresh token will be issued. In that case, you should not keep your refresh token. Because whether you delete or not, on next login refresh token will be issued again (if your grant allows).

Why are refresh tokens more secure?

The reason for that is the sensitivity of this piece of information. You can think of it as user credentials, since a Refresh Token allows a user to remain authenticated essentially forever. Therefore you cannot have this information in a browser, it must be stored securely.

How do I know if my token is expired?

This can be done using the following steps:

  1. convert expires_in to an expire time (epoch, RFC-3339/ISO-8601 datetime, etc.)
  2. store the expire time.
  3. on each resource request, check the current time against the expire time and make a token refresh request before the resource request if the access_token has expired.

Where are refresh token browsers stored?

You can store encrypted tokens securely in HttpOnly cookies. If you worry about long-living Refresh Token. You can skip storing it and not use it at all. Just keep Access Token in memory and do silent sign-in when Access Token expires.

Should refresh tokens be encrypted?

The Refresh Token, when paired with the Client ID and Secret can be used to generate a new Access Token. It should be securely stored and encrypted. You should only store those tokens that are necessary for your application to function alongside your codebase.

Why is JWT bad?

Bottom line. Although JWT does eliminate the database lookup, it introduces security issues and other complexities while doing so. Security is binary—either it’s secure or it’s not. Thus making it dangerous to use JWT for user sessions.
