UnverifiedThe OAuth 2.0 specification defines a standard Token Revocation interface in RFC 7009, allowing clients to actively revoke tokens.77% similarUnverifiedIn OAuth 2.0, after a refresh token is revoked, the access tokens issued by it should theoretically also become invalid, but in practice this propagation often depends on an additional revocation list mechanism.74% similarUnverified该鉴权机制本质上是 OAuth 2.0 Bearer Token 模式的简化版本，省去了授权码交换和 Token 刷新等握手流程72% similarUnverifiedThe agent exchanges the authorization code for an access token at the token endpoint, and after the token expires, it can use a Refresh Token to obtain a new access token without requiring the user to authorize again.67% similarUnverifiedThe second layer of the two-layer access model is built on a Token Exchange mechanism, whereby the Agent uses the delegated token to dynamically exchange access tokens for target applications through the identity provider, rather than pre-storing credentials for all applications.66% similar
