Document sites that support app-specific passwords

[jmagman]

App-specific passwords allow apps or devices to sign into a 2FA account without actually requiring the second authentication method.

For example, Betterment will generate a random 20-character password so a site like Mint can authenticate without needing the secondary Betterment code. Google, Apple, Microsoft, FastMail, Yahoo, Betterment, and others support app-specific passwords.

It would be great for this to be aggregated on https://twofactorauth.org instead of the currently required spelunking through FAQ and settings menus for every site.

How do you envision this information would be displayed?

[jmagman]

The most obvious would be another checkmark column, but that might be overkill when most categories would not contain any supported sites, so would just have an empty column. Maybe another icon in the same place as "Exceptions & Restrictions"? font-awesome key or unlock-alt would work.

I'm not opposed to this kind of solution.
@2factorauth/collaborators feedback?

(It would be nice if those sites restricted application-specific passwords to specific functions. ie this password would work only for checking gmail, but not gdrive.)
