The user can reactivate an existing account. During the Mobile Authenticator Studio life cycle, users may have to reactivate the app for various reasons. Reactivation may be necessary in the following scenarios:
A user has lost their app PIN code. Because the authenticator key cannot be used without the local password, the app can no longer generate valid OTPs or e-signatures.
The user can reactivate the app via the Manage Accounts screen by activating the account with the Scan code button.
A user has lost the device, and the app on the new device should have the same configuration and secret.
The user needs to reinstall the app and activate it with the parameters provided by the server.
If the reactivation feature is enabled, you must provide the event reactivation counter (ERC) to the user who must enter it in the app, together with authenticator's activation data (serial number and activation code). This can be done manually or included in the QR code or Cronto image.
The user starts the process from the Manage Accounts screen. The reactivation procedure is almost identical to the activation procedure. The only difference to a regular activation is that for a reactivation, if the app is protected, the user will be prompted to authenticate using the PIN or biometric method configured for the first account.
For the activation steps, see Manual offline activation and Offline activation via image.
