Can I use Protectimus OTP for Firefox 2FA, instead of Google Authenticator or Authy, or the others listed in the 2FA guidance?
The Firefox 2FA setup guide lists Google Authenticator, Authy, FreeOTP, and a few others.
Can I use Protectimus OTP for Firefox 2FA, instead of Google Authenticator or Authy, or the others listed in the 2FA guidance? I already have some other accounts set up with Protectimus and would prefer to stick with one 2FA authenticator app.

Each system has their own 2FA implementation and Google has the Authenticator. I would say using 2FA is asking for trouble if your not up to date with making sure your keys and passwords are correct otherwise if you loose any parts of the 2FA consider the account lost. I stopped using 2FA because of this issue on another site that I used to have 2FA until the keys I had stopped working and the account was locked out and I had the system manager delete the account and recreated it again but no longer use 2FA because of that. Once your locked out of 2FA consider the account lost. No one is going to be able to fix that.
You can install both apps and compare the TOTP code they generate. This code is valid for thirty seconds and as long as an app generates the correct code you can use it. You may have to disable and re-enable 2FA to get a QR code you can use. You can possibly make a screenshot of the QR code or save the otpauth:// link code.
