Are refresh tokens bad?
A Single Page Application (normally implementing Implicit Grant) should not under any circumstances get a Refresh Token. 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.
Should you store refresh tokens in a database?
You can replace the refresh token on each refresh, but remember that you need to store all expired refresh tokens until their lifetime is over. From a security perspective it makes sense to create a new token, but it is a trade off between security and amount of data in your database.
Should refresh token be hashed?
You only need to keep “exp” in the database to know when it’s safe to clean records out. Since the “jti” is just a random identifier, you can’t get back from the “jti” to any identifiable information so there’s no particular need to hash or encrypt it.
When to use refresh token and access token?
Refresh Token is used to retrieve the Access Token. Access Token gets expired after some time. Instead of sending a Request, we use Refresh Token for security purpose. For example, we send a username and password for accessing the token. If we send the username and password with every request, there is a big chance of these getting hacked.
What happens when you exchange an access token?
The response will be a new access token, and optionally a new refresh token, just like you received when exchanging the authorization code for an access token. If you do not get back a new refresh token, then it means your existing refresh token will continue to work when the new access token expires.
