Two-factor authentication (2FA) is a form of multi-factor authentication that helps verify the identity of the person logging into your account using two methods, or factors, of authentication:
2FA reduces the risk of cyber-attacks such as phishing, malware, and other attempts to take over your account.
Below are answers to frequently asked questions about 2FA.
Security attacks are growing in complexity. Hackers are always looking for security weaknesses, and weak or stolen passwords remain their primary entry point. Passwords alone are no longer enough, so 2FA is more important now than ever. With 2FA, even if someone has your password, chances are they don't have your device also.
Yes, 2FA is required for all McGill accounts.
The frequency of authentication prompts reflects our ongoing efforts to ensure maximum security.
Accessing applications with different levels of security tasks will require different authentication frequency prompts:
Security level | Authentication frequency |
Low | Every 30 days |
Medium | Weekly |
High | Daily |
VPN authentication | Per use |
This applies to all staff, faculty, and students working at McGill, regardless of whether a user is on or off campus.
These measures are crucial in protecting our digital ecosystem.
When SMS (texting) and voice protocols were developed, they were designed without encryption, meaning signals can be intercepted in various ways. Hackers can trick mobile carriers into redirecting a phone number to a new device, which is known as a SIM swap. Once a hacker has redirected your phone number, they no longer need your physical phone to access your 2FA authentication codes. If you sync your text messages with your laptop or tablet, a hacker could access your texts by stealing your device.
An authentication app like Microsoft Authenticator is safer because it doesn’t rely on your mobile carrier. The codes are in the app and expire quickly, usually within 30 seconds. An authentication app is also faster because you only need to tap a button to verify your identity instead of manually entering a six-digit code.
2FA currently supports iOS, Android, and Windows OS. Please contact the IT Service Desk to discuss your options if your device uses a different operating system.
Download OneAuth on your desktop or laptop. If this is not an option, contact the IT Service Desk.
2FA requires email applications that support Modern Authentication, such as Outlook. See the Index of setup instructions of McGill email for information on supported email applications and devices.
IMPORTANT: Staff and faculty are not allowed to forward McGill email to a non-McGill email service; this would violate the Policy on the Responsible Use of Information Technology Resources. For more information, see the IT Knowledge Base article Options for dealing with multiple email services.
Self-Service Password Reset (SSPR) is a Microsoft feature that provides 2FA users with the ability to reset their password if they have forgotten it or are locked out of their account. You can reset your password using two authentication methods you set up when configuring 2FA, such as acknowledging a notification or text message sent to your mobile device.
NOTE: When you reset your password using SSPR, you reset the McGill password you use in conjunction with your username. This is the same password you use to log in to your computer, Minerva, D2, etc.
Because your primary phone number and the Microsoft Authenticator app are probably on the same phone, setting up a secondary number is important. This will be the fastest way to get back into your account if your phone is lost or stolen. It is strongly recommended that you set up multiple authentication methods so if one method becomes unavailable, you can still authenticate with another.
For detailed instructions on adding and managing authentication methods, see View and Modify 2FA and SSPR account settings.
If you receive an Authenticator app notification when you are not in the process of logging in, it may be coming from a secondary device (e.g., a device that your spouse or child is logging into). If you are unaware of someone authorized to log into a secondary device, select "Deny" to protect your account and report it to the IT Service Desk immediately.
It happens. You left your mobile device at home, and now you can't use your phone to verify your identity. If you previously added another method to sign in to your account, such as your office phone, you should be able to use that method now. Otherwise, you'll have to contact the IT Service Desk to have your account reset.
To sign in to your work or school account using another verification method:
If you've lost or had your mobile device stolen, you can either sign in using a different method (see What if I forget my mobile device? above) or ask the IT Service Desk to clear your settings. We strongly recommend letting the IT Service Desk know if your phone was lost or stolen so that the appropriate updates can be made to your account. After your settings are cleared, you'll be prompted to register for 2FA the next time you sign in.
It is strongly recommended that you set up multiple authentication methods, ideally the Microsoft Authenticator app and text, so that if one method becomes unavailable, you can recover it using another.
If text is your primary authentication method, no action is required.
If Microsoft Authenticator is your primary 2FA authentication method, you will need to take the following steps:
It is strongly recommended that you set up multiple authentication methods, ideally the Microsoft Authenticator app and text, so that if one method becomes unavailable, you can recover it using another.
If Microsoft Authenticator is your primary 2FA authentication method, no action is required.
If text is your primary 2FA authentication method, you must update your 2FA authentication methods before your number is changed. Once the old number is gone, you will not be able to authenticate with 2FA if the old number is still associated with your account. Since you may not know what your new number will be, you have a few options:
For instructions on modifying your authentication methods, see the IT Knowledge Base article View and modify 2FA and SSPR account settings.
It is strongly recommended that you set up multiple authentication methods, ideally the Microsoft Authenticator app and text, so that if one method becomes unavailable, you can recover it using another.
The Microsoft Authenticator App is recommended when you travel or need to access your McGill account while out of the country. Get the app directly from the App Store (iOS) or Google Play Store (Android). The app does not require an internet connection or data. There are no roaming fees when using the app.
The Microsoft Authenticator App will:
If you are using text as the default authentication method, there are two ways to switch to the Authenticator app. Note that Method 1 changes your default authentication method for all subsequent sign-ins, while Method 2 allows you to use a different one-time method.
To switch to the Authenticator app:
