This code can be transmitted via a text message, a phone call, or can be generated by something called an authenticator app. But the second is a special code that is sent to a device you have under your control. (Curiously, it has still not added this option to Office 365.) This functionality, available to Google account holders since 2011, requires you to enter two pieces of information when you access your account. And you can enable it to provide authentication codes for multiple accounts.īack in April, Microsoft announced that it was adding two-step authentication to its Microsoft Account.

But two-step authentication can also be a bit of a pain, and managing multiple accounts adds to the misery.


I've enabled two-step authentication on all of my online accounts that support it because doing so is more secure.
