When should I refresh my access token?

What happens when refresh token expires?
Refresh tokens can expire, although their expiration time is usually much longer than access tokens. Refresh tokens can become invalid in other ways (for example if your user revokes your OAuth client app’s access — in this case all your refresh tokens and access tokens for that provider would be invalidated).
What’s the point of a refresh token?
A refresh token is a special token that is used to generate additional access tokens. This allows you to have short-lived access tokens without having to collect credentials every time one expires. You request this token alongside the access and/or ID tokens as part of a user’s initial authentication flow.
How do you check access token is expired or not in Web API?
2 Answers. The easiest way is to just try to call the service with it. It will reject it if it is expired and then you can request a new one. You can also keep the time you received the token and use the expires_in to calculate when it will approximately expire.
How do I know if my OAuth token is expired?
This can be done using the following steps:convert expires_in to an expire time (epoch, RFC-3339/ISO-8601 datetime, etc.)store the expire time.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.
How do I protect my refresh token?
If you are storing the refresh token on the server, your server should include a secure session cookie in the authentication response to identify the user. You can prevent attackers from extracting secure session cookies by setting the cookies with the HttpOnly flag.
How do access tokens work?
Access tokens are used in token-based authentication to allow an application to access an API. The application receives an access token after a user successfully authenticates and authorizes access, then passes the access token as a credential when it calls the target API.
Is refresh token secure?
If you are storing the refresh token on the server, your server should include a secure session cookie in the authentication response to identify the user. You can prevent attackers from extracting secure session cookies by setting the cookies with the HttpOnly flag. The cookie wouldn’t be a refresh token.
How do you handle expired JWT tokens?
There are three ways:Changing the secret key. This will revoke all tokens of all users, which is not acceptable.Make each user has his own secret and just change the secret of a specified user. Now the RESTful backend is not stateless anymore. … Store the revoked JWT tokens in Redis.

The Refresh Token grant type is used by clients to exchange a refresh token for an access token when the access token has expired. This allows clients to continue to have a valid access token without further interaction with the user.
How long should JWT tokens last?
around 15 minutesThis is why JWTs have an expiry value. And these values are kept short. Common practice is to keep it around 15 minutes, so that any leaked JWTs will cease to be valid fairly quickly.
Why do Oauth tokens expire?
However, this means there is no way to expire those tokens directly, so instead, the tokens are issued with a short expiration time so that the application is forced to continually refresh them, giving the service a chance to revoke an application’s access if needed.
