Does Two Factor Authentication Actually Weaken Security?

11 Jun

Readers of this blog will know that I am a strong advocate of two-factor authentication, commenting on it in various blog articles.

This article by Paul Moore caught my attention this week:

The lesson is if a service offers two-factor authentication, then you really ought to switch it on.
