Just wanted to suggest this too. Has it been considiered yet?
2-Factor App Authentication
Please enable the option for using mobile authenticator apps like Authy, Google Authenticator or Microsoft Authenticator. Currently there is only the option to enable 2-factor email authentication which is a bit of a tedious process, that's all. Thanks.
This will be really nice option. I agree with ULTRAMAG
See no harm in this being done, people invest a lot of time on this website so I can understand people wanting to keep their profiles safe.
I really really hope they finally use the mobile 2fa app , too.
Their "mail" authentication code, for example, didn't even arrive to my old account.
