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?
for semi serious accounts i use the inbuild totps from bitwarden premium (knowing full well that if someone gets access to my bitwarden he gets access to those accounts - but its just sooo damn convinient)
for super serious accounts i use yubikeys (3x) with fido2 if supported and if not at least totp through yubikey with their app.
