Installing the Microsoft Authenticator app

The Microsoft Authenticator app allows you to verify logins using notifications or generated codes.

Linking the app to your account

    • A QR code will be displayed.
  2. In the app:
    • In the Microsoft Authenticator app, tap “Scan a QR code”.
    • Scan the code shown on your computer screen.
  3. Verify the account setup:
    • You will be prompted to enter a code in the Microsoft Authenticator app or approve a notification.

Setup complete

Once setup is successful, your account will be protected with MFA. Each time you sign in, you will:

  • Verify access through Microsoft Authenticator (notification or code).

 

RECOMMENDED: Enable passwordless sign-in in Microsoft Authenticator

Passwordless sign-in is a more secure and convenient alternative to traditional password-based login. Microsoft Authenticator allows you to verify your identity using biometrics (fingerprint, facial recognition) or a PIN directly in the app. During the activation process, your device will be registered with the ČVUT Entra system.

  1. On your phone, open the Microsoft Authenticator app.
  2. In the app, select your Work or school account.
  3. Enable the option Enable phone sign-in
  4. The app will guide you through the setup step by step.
    1. During the process, you will be asked to verify your identity:
      1. Enter your PIN or use biometric verification (e.g., fingerprint or face recognition).
      2. The app will confirm that you are the rightful owner of the account.
  5. Once the verification process is complete, a confirmation of successful setup will appear.

 

 

Enabling Passkey sign-in in Microsoft Authenticator

Passkeys are a modern way of signing in without passwords – using your fingerprint, face, or PIN instead. They are more secure and convenient than traditional passwords.

What will you need?

  • A phone with Android 14+ or iOS 17+
  • The Microsoft Authenticator app configured

How to set up a Passkey:

  1. On your phone, open the Microsoft Authenticator app.
  2. In the app, select your Work or school account.
  3. Select Create a Passkey
  4. If you haven’t already, set up a screen lock on your mobile device!
  5. Allow Microsoft Authenticator to be your Passkey provider
