Consent

In identity systems, the user's explicit permission for an application to access their identity information or act on their behalf, captured during authorization flows like OAuth so access is granted with the user's awareness and agreement.

When an app requests access to a user's data or to act for them, consent is the step where the user is shown what is being requested and agrees (or declines). It is central to delegated authorization protocols like OAuth and to privacy: consent screens make scope visible, and consent records support accountability. Attackers abuse consent through 'consent phishing,' tricking users into granting a malicious app access, so consent handling is a security concern as well as a privacy one.

Introduced in: Identity and Access Management

Examples

  • An OAuth consent screen asking a user to allow an app to read their calendar.
  • A user declining an app's request for excessive permissions.
  • Recognizing consent phishing where a malicious app requests broad access.
