Add Bitbond

Bitbond requires users to use 2FA when signing in from a new device. If you login from the same device twice you won’t be asked for 2F.

Thanks for the pull request, @jareknowotka. Does Bitbond have any documentation regarding their implementation of two-factor authentication?

[jareknowotka]

Thanks for asking, unfortunately not, we don't provide documentation regarding 2FA.

@jareknowotka if that's the case could you send some screenshots and describe how you've implemented 2FA?
What 2FA options you support and so on.

Thanks for registering! The authorisation flow for a user singing in from a new device looks like that:

The last screen requires a token from a method user has selected as his 2FA.
