Configuring Microsoft Authentication App with 365 Emails & Passwordless Sign In

Office 365 has made an app which helps to integrate MFA and to easily set up and use password-less sign in.

Password-less sign in sends the user a notification on their phone and bypasses needing a text, call or to generate an OTP (one-time password).

9. On your phone, click ‘Scan QR code’ and scan the QR code on your laptop screen
