2 factor authentication

[Felix]

Hi Bigin,
thanks for replying,

There is a key generated during the registration and the email address needs to be verified with it.
You could use this and also extend your login process and utilize the same method to generate a one-time key.

What I understand from a two factor login, is what makes it strong is by doing the second verification step
not over the internet but over a different network such as a mobile phone network e.g. with an sms
