How to Respond When an MFA Device Is Lost or Replaced

11/10/2026

Replacing an authentication device can create both account lockout and account takeover risk.

Checks to make

Verify identity through an approved recovery path, revoke the lost factor and active sessions when warranted, issue a new factor, and review recent sign-in activity. Avoid bypassing controls through an unverified phone request.
