Your question: Why do Oauth tokens expire?

Why do auth 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.

Are OAuth tokens permanent?

The permanent token is a normal token that never expires: you can obtain it once and then use it as long as you want without needing to refresh or re-authenticate. This means you can build standalone integrations without any web server to support the OAuth 2.0 authorization flow.

Do OAuth refresh tokens expire?

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 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.

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.

How do I persist access token?

Most guidelines, while advising against storing access tokens in the session or local storage, recommend the use of session cookies. However, we can use session cookies only with the domain that sets the cookie. Another popular suggestion is to store access tokens in the browser’s memory.

The JWT access token is only valid for a finite period of time. Using an expired JWT will cause operations to fail.

How do handle tokens expire?

There are three ways:

  1. Changing the secret key. This will revoke all tokens of all users, which is not acceptable.
  2. Make each user has his own secret and just change the secret of a specified user. Now the RESTful backend is not stateless anymore. …

Update Access Token Lifetime

  3. Click Save Changes.

How is OAuth token validated?

The access token

A resource server validates such a token by making a call to the authorisation server’s introspection endpoint. The token encodes the entire authorisation in itself and is cryptographically protected against tampering. JSON Web Token (JWT) has become the defacto standard for self-contained tokens.
