A recovery code is a unique code, generated by Auth0, allowing a user to regain account access. So if a user cannot access the device or account used for (MFA) enrollment, they can use a recovery code to authenticate.

​
How it works

When using with recovery codes enabled:
  1. A user starts MFA enrollment.
  2. Auth0 generates a recovery code.
  3. During MFA enrollment the user is shown the recovery code prompt.
  4. The user saves the recovery code and completes the enrollment process.
  5. Now the user can complete MFA with the recovery code they saved if they lose access to their device or account they enrolled for MFA.
Example recovery code prompt during multi-factor authentication enrollment
When using Universal Login with recovery codes disabled:
  • Users will not see the recovery code prompt during MFA enrollment.
  • Users cannot authenticate with a recovery code.

​
Enable recovery codes

Recovery codes are disabled by default. You can enable recovery codes by going to Dashboard > Security > Multifactor Auth.
