What is Multi-Factor Authentication (MFA), and why do you need an extra step when signing in?

Detailed Information

What is MFA?

Multi-Factor Authentication (MFA) is a security method that requires more than just your password to sign in.

After entering your login credentials, you must confirm your identity using a second step, such as a code or approval on your phone.

How MFA Works

  1. Enter your username and password.
  2. The system asks for a second form of verification.
  3. Approve the sign-in or enter a code from your device.
  4. You are signed in after verification is complete.

Examples of MFA Methods

  • Authenticator app (such as a mobile app that sends a notification or generates a code)
  • Passkey (a secure sign-in method using your device, such as face recognition, fingerprint, or a PIN)

Why MFA is Important

  • Adds protection: Keeps your account safe even if your password is stolen.
  • Prevents unauthorized access: Stops others from signing in as you.
  • Protects sensitive data: Helps secure your personal and university information.
WARNING: Never approve a login request that you did not start. If you receive unexpected verification prompts, deny the request and change your password immediately.

What You Might Notice
