Have you reinstalled the MobileID app or a new smartphone? Here’s how to recover your MobileID so you can continue to sign with sproof sign.

Initial situation
You have already successfully identified yourself once via a VideoIdent procedure for a qualified digital signature. You have now reinstalled the MobileID app or you have received a new smartphone and now want to reinstall the MobileID app. They want to reactivate the MobileID so that they can sign again in a qualified manner without another VideoIdent procedure.

Solution
With backup code
You made a note of the backup code when you first installed the MobileID app. Before setting up the app again, go to https://www.mobileid.ch/de/login, enter your phone number, and recover your identification. Now you can sign qualified with sproof sign again without further identification.

Without a backup code
You have lost the backup code or you had a backup code, but have set up the Mobile ID app again in the meantime. In this case, a new identification is required. Proceed as follows:

Uninstall the MobileID app (if the app is not currently installed, skip this action)
Reinstall the MobileID app and write down the backup code. Keep this code safe.
In the settings under QES Setup, perform a new identification.
