Credentials & User Impersonation

OAuth 2.0 Device Authorization Grant

T1528 · MITRE ATT&CK

Abuse the OAuth 2.0 device authorization grant by initiating a request for a registered public client and persuading a user to enter the returned user_code at the identity provider's legitimate verification_uri. After the user completes the provider's normal authentication and authorization checks, the client receives tokens for the granted scopes. This is application-token theft, not an inherent MFA bypass; the user may complete MFA normally.
