Topic: Two factor authentication

[JohnG]

Is there a way to implement two factor authentication within SME email similar to the way gmail works? I searched but couldn't find much.

When you say 'the way gmail works', do you mean webmail, or every possible client app (outlook, thunderbird, apple mail, iphone, android)?

Critics are quick to point out the shortcomings of two-factor authentication: it usually requires a USB token, phone, or other device that's easy to lose; you sacrifice some privacy by having to disclose your telephone number to a third party; and it is subject to "man-in-the-middle" and other browser- and app-based attacks.
