What is the use of refresh token in oauth2?
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.
What is the use of refresh token?
A Refresh token is a string that represents an authorization that was granted to a client to use a particular set of web services on behalf of a user to access data for a particular institution. Refresh Tokens are issued to the client by OCLC’s Authorization Server upon request of an Access Token.
How do you handle refresh token?
To use the refresh token, make a POST request to the service’s token endpoint with grant_type=refresh_token , and include the refresh token as well as the client credentials.
When to use a refresh token in OAuth 2.0?
OAuth 2.0 Refresh Token Flow After a client—via a connected app—receives an access token, it can use a refresh token to get a new session when its current session expires. The connected app’s session timeout value determines when an access token is no longer valid and when to apply for a new one using a refresh token.
What happens when a refresh token is leaked?
This means when a client gets a refresh token from a server, this token must be stored securely to keep it from being used by potential attackers. If a refresh token is leaked, it may be used to obtain new access tokens (and access protected resources) until it is either blacklisted or it expires (which may take a long time).
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.
What are the benefits of refresh tokens in Java?
