Idea: Include basic threat modeling to help users choose 2FA method

[conorgil]

After someone says that they enabled 2fa on a site, ask them which method they enabled. Then, 2fan can record which methods of 2fa were available at the time they enabled 2fa and notify them if a new method becomes available in the future. Initially, could hard code the method rankings and notify on methods that are more secure and better ux. But, ideally it takes into account the users personal threat model based on them answering some questions and/or creating a custom ranking based on their own needs.
