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?
You should be backing up your secrets to some type of app like Vaultwarden or KeePassXC.
And you shouldn’t need to VM host an android OS just to have a secondary means of authenticating. There are plenty of apps out there that support adding your secrets.
Vaultwarden, Bitwarden, KeePassXC, or hell, a Yubikey 5 device and then use Yubikey Authenticator.
How do you back up your secrets? Do you have to do it at the time you first see them?
