Hashing refresh tokens before storing (or retrieving) is recommended both to prevent a compromise of this database from leaking valid tokens and to prevent string comparison timing attacks; assuming the refresh tokens are cryptographically secure random strings (as they should be!), a single unsalted round of a fast secure hash like the SHA2 or An innovative idea is to use JSON Web Tokens (JWT) to transport and validate data without the need for a database. Reload to refresh your session. An attacker may obtain refresh tokens from the authorization server's When you are building services for everyone to access online, you need have a way protect resources so that only the user can access data belonging to them only.
