  • Once you receive this notification, click the “verify” button.
Your verification is complete. Additionally, you’ll have to enter your mobile phone number just in case you lose access to the app. With this, you’ve set up your contact method.

Setting up app passwords

Next, you’ll have to set up app passwords for nonbrowser apps like Outlook.
Here are the steps for it.
  • After you enter your phone number, click the “next” button. This should take you to “generate app password” screen.
  • Click the “generate app password” button and the system will automatically generate a random password for you.
  • If you need additional app passwords, click the “I’ll need more app passwords” button. Otherwise, click the “done” button.
Now, when you log into your Office 365 portal, a secondary authentication notification is automatically sent to your mobile device. And once you verify, you can sign in.

Setting up text messages

Once your contact method is set up, you can choose to verify through a text message or phone call as well.
On this screen, click the “next” button and this should text a six-digit code to your phone. Enter this code in the box displayed in your browser and press the “verify” button. This should authenticate you to use the Office 365 portal.

Changing MFA settings

You can always change your MFA settings at any time. To do that, log into your Office 365 portal and look for a small wheellike icon on the top right-hand corner. When you click on it, you’ll get a drop-down menu with different options.
