OAuth 2.0 Token Exchange

OAuth 2.0 Token Exchange is an extension to the OAuth 2.0 protocol that allows a client to exchange one token for another. This can be useful in scenarios where a client needs to obtain a different type of token to access a resource or service.

Why Token Exchange?

Token exchange is useful in a variety of scenarios, such as:

• Delegated Access: A client may need to exchange an access token for a different type of token that grants access to additional resources or services on behalf of the user.
• Token Refresh: A client may need to exchange a refresh token for a new access token when the current access token expires.
• Token Translation: A client may need to exchange a token issued by one authorization server for a token issued by another authorization server.
