To speed this along, Microsoft has started deprecating Legacy Authentication Protocols in 365. Microsoft is urging organizations to do this as soon as possible. With that said, the push to turn off Legacy Authentication protocols is in full swing. This makes it very easy to steal credentials. Also, most credentials are stored on the device they are used on.

In today’s world, this is problematic because these usernames and passwords can be easily compromised. Basic Authentication is simply referring to an app, client, or protocol that is only passing a username and password for authentication.īasic Authentication has been the sole form of authentication for most applications and protocols for many years. Legacy Authentication is often referred to as Basic Authentication. To understand MFA a little more, let me explain Legacy Authentication and Modern Authentication, and how it is important to have a successful MFA implementation.

Multi-Factor Authentication, aka MFA, allows you to secure user logins by adding multiple authentication methods.
