Available Authentication Methods

Microsoft Authenticator App (Recommended)

The Microsoft Authenticator app is the recommended authentication method for most users due to its convenience and security features.

Key benefits:

• Receive push notifications for quick approval
• Generate verification codes when offline
• Use across multiple devices
• No cellular service required

Getting started:

1. Download the Microsoft Authenticator app from your device's app store
2. Select "Add account" in the app
3. Choose "Work or school account"
4. Follow the on-screen instructions to link your SIUE account

Text Message or Voice Call

Receive verification codes via SMS text message or automated voice call to your registered phone number.

How it works:

1. When signing in, you'll be prompted for additional verification
2. Select either "Text" or "Call" option
3. Receive a verification code via your chosen method
4. Enter the code on the sign-in screen

Note: This method requires cellular service and may incur standard text/call charges based on your mobile plan.

Hardware Token

A physical device that generates verification codes without requiring a smartphone or internet connection.

Details:

• Hardware tokens cost $25 per device
• Ideal for users without smartphones or in areas with poor connectivity
• Available in USB or wireless formats
• To request a token, contact the ITS Help Desk at (618) 650-5500 or help@siue.edu

Alternate or Backup Phone

Register an additional phone number as a backup authentication method.

Important caution:

• Using an office phone as a verification method is not recommended for Teams phones
• This can create an authentication loop where you need MFA to access the phone that receives MFA codes
• Personal mobile phones or home landlines are better backup options

Managing Your MFA Methods

You can update, add, or remove authentication methods at any time:

1. Sign in to your SIUE account
2. Navigate to My Account > Security Info
3. Select "Add method" to add a new verification option
4. Select "Change" next to an existing method to update it

Best Practices for MFA

• Set up multiple authentication methods as backup
• Keep your contact information current
• Test your authentication methods periodically
• Contact the ITS Help Desk immediately if you lose access to all your verification methods

Frequently Asked Questions

What if I get a new phone?

If you replace your device, you'll need to set up the Microsoft Authenticator app again. Make sure you have a backup method available during this transition.

What if I'm traveling internationally?

We recommend setting up the Microsoft Authenticator app with offline codes before departure for international travel, as text messages may not be reliably delivered internationally.
