Configuring Microsoft Authentication App with 365 Emails & Passwordless Sign In

Office 365 has made it super easy to integrate Multi-Factor Authentication (MFA) and set up password-less sign-in.

This means you can receive a notification on your phone and skip the hassle of texts, calls, or generating one-time passwords (OTPs).

Let’s walk through the steps to get this set up:

Log into Office 365: Open your web browser and go to www.office.com. Once there, open the Outlook app.

Access Your Account Settings: Click on your user icon and select ‘View Account’. On the account page, click ‘Update Info’ and then ‘Add Method’.

Choose Authentication Options: You’ll see several authentication options. Click on ‘Authenticator App’ and then ‘Add’.

Download the Authenticator App: You’ll be prompted to download the Microsoft Authenticator app to your phone. Head over to the Apple App Store or Google Play Store and search for ‘Microsoft Authenticator’. Once downloaded, click ‘Next’ on your computer.

Set Up the App on Your Phone: On your phone, allow notifications if prompted, and then add an account set up by your ‘Work or School’.

Scan the QR Code: Back in Outlook, click ‘Next’ and you’ll see a QR code. On your phone, click ‘Scan QR code’ and scan the QR code displayed on your computer screen.

Verify Your Account: Your Office 365 account should now appear in the authenticator app. Tap on your account to see OTPs being generated. You can use these to sign in.

Enable Password-less Sign In: To enable password-less sign-in, click ‘Enable phone sign-in’. The app will ask you to register your device – click ‘Continue’. Enter your email address and password, and you’ll receive a code in your authenticator app. Enter the code in Outlook and click ‘Verify’, then tap ‘Register’.
