It would be nice to be able to change my Authenticator (TOPT) settings without having to first delete all of my 2FA keys. I simply want to switch from using Authy Authenticator to a different Authenticator app, but to do so I have to first turn off 2FA, which deletes all my 2FA keys. Most apps allow me to simply delete Authenticator app as a 2FA option, and then re-add it.
