One of the best ways to stay secure is to have multiple methods of authenticating. This typically means something you know (like a password) and something you have (a swipe card). The reason for this is that most people don’t maintain secure passwords, however with the introduction of multi factor methods security is significantly enhanced..
Microsoft has announced that it has now enabled multi factor authentication for Office 365 M and E plans.They did so in this recent blog post:
The great thing with is that multi factor authentication can be enabled on a per user basis and uses a variety of methods for the second factor including:
1. Call my mobile phone. The user receives a phone call that asks them to press the pound key. Once the pound key is pressed, the user is logged in.
2. Text code to my mobile phone. The user receives a text message containing a six-digit code that they must enter into the portal.
3. Call my office phone. This is the same as Call my mobile phone, but it enables the user to select a different phone if they do not have their mobile phone with them.
4. Notify me through app. The user configured a smartphone app and they receive a notification in the app that they must confirm the login. Smartphone apps are available for Windows Phone, iPhone, and Android devices.
5. Show one-time code in app. The same smartphone app is used. Instead of receiving a notification, the user starts the app and enters the six-digit code from the app into the portal.
Having more methods to secure login is a good things and is already available if you currently have Office 365 M or E plans. So, if you want to add an additional layer of security to Office 365 logins look at enabling it for users.
