What I have seen though are Microsoft and Google trying to maneuver their own auth app and hiding the generic OTP option to lock people in.
As long as I can use any generic OTP app I'm happy, and Aegis is definitely my current favorite. I mean I'm a person with close to 50 OTP codes at this time, this is a serious tool in my life.
I just have a strong vault password for my vault and that should be more than enough I guess
I use a Yubikey as the 2FA for my bitwatden, then store all the TOTP codes with the passwords in the same vault. Quite convenient, and also adheres to the principles of MFA
If you were to use two apps / two stores, there is another hurdle.
Depending on your threat model, this solution is ok — way better than no 2FA at all or SMS.
1Password has a nice article regarding this point: https://blog.1password.com/1password-2fa-passwords-codes-tog...
Anyway, Aegis and Ente have export options, Aughy doesn't.
It is a pain to switch over; but that is the way it is with all sorts of proprietary programs. They just tighten the noose regardless if you pay or not.
Once you get rid of the noose, it's no longer a hassle.
For everyone going through this situation, please do a little bit of homework and read up on the capabilities of whatever alternative you're going to pick, and make sure that your data is yours and under your control, and you can back it up in a readable format.
