Yesterday, I accidentally removed an authenticator app from my phone. Fortunately, I have another copy of the app on a different device. It made me realize how easy it is to lock myself out of my accounts. Do you think it’s a good idea to create a Windows VM with an Android emulator on it and install copies of all my authenticator apps, this will not cause any security issues?
why not consolidate your auth apps?
i use selfhosted vaultwarden (with backups ofc) for everything, except for vaultwarden, which is protected by authy . and authy can be backed up easily
Sane MFA apps explicitly disallow their data from being backed up. That would be a massive attack vector if it was possible.
