How do I store authentication tokens?
How to securely store JWTs in a cookie. A JWT needs to be stored in a safe place inside the user’s browser. If you store it inside localStorage, it’s accessible by any script inside your page. This is as bad as it sounds; an XSS attack could give an external attacker access to the token.
What should be expiry of access token?
By default, access tokens are valid for 60 days and programmatic refresh tokens are valid for a year. The member must reauthorize your application when refresh tokens expire.
Should I store token in cookie or localStorage?
Although cookies still have some vulnerabilities, it’s preferable compared to localStorage whenever possible. Cookies are vulnerable to CSRF attacks, but it can be mitigated using sameSite flag and anti-CSRF tokens.
Where does the authorization server store the token?
The authorization server could store the token in the request body (e.g., in JSON format) rather than in a cookie. However, this makes no difference, because the client can see and process the entire response anyway.
What’s the purpose of the auth code flow?
From what i understand the purpose of the Authorization Code flow is to exchange the auth code for access token. This exchange happens between the server which serves the page and authorization server so that the actual access token is not exposed to the client user.
How to exchange authentication code for access token?
The token request, which exchanges the authentication code for an access token, is done by the web application server, and the web application server should authenticate itself with the authorization server (e.g., using a shared client_secret ).
Which is the best way to store and reuse tokens?
Store and reuse: Reduce unnecessary roundtrips that extend your application’s attack surface, and optimize plan token limits (where applicable) by storing access tokens obtained from the authorization server. Rather than requesting a new token, use the stored token during future calls until it expires.
