Setting Up Two-Factor Authentication

Where to start
There are two parts involved in two-factor setup:
- Part one: Choose how you’ll generate codes
- Part two: Add two-factor to your TMU account
Part one: Choose how you'll generate codes
You have the option of using a mobile device or using a universal second factor (U2F) security key.
TMU employees may also choose to use a one-time verification (OTV) code generator.
If you’re using a mobile device
You’ll need to install the Google Authenticator app on your device. Do not delete Google Authenticator once installed, as you’ll need it for the entire duration of your time at TMU.
This option does not use text messaging, mobile data or WiFi to operate.
On your Android device, open the Play Store app.

Search for Google Authenticator.

Tap the Google Authenticator option in the search screen and then tap Install.

When asked to authorize Google Authenticator to access information on your device, tap Accept if you wish to continue. You’ll be returned to the app screen. Press the back button to return to your home screen.

The Authenticator app should now be on your home screen. Tap the icon to run the app.
Once this is complete, you can start Part two: Add two-factor to your TMU account.

On your iOS device, open the App Store.

Search for Google Authenticator.

Find Google Authenticator option in the search screen and then tap GET.

Tap the INSTALL button.

The Google Authenticator app will now install and create an icon on the main screen of your iOS device. Tap the icon to run the app.
Once this is complete, you can start Part two: Add two-factor to your TMU account.

If you're using a U2F security key
Universal second factor (U2F) keys are USB devices that can be plugged in to your computer to provide authentication for two-factor logins.
The least expensive model is likely the HyperFIDO Mini which normally retails for around $10 and can be purchased online or at the TMU Campus Store. Note that U2F security keys only work with Google Chrome or Firefox browsers.
TMU employees can check with their faculties or departments for approval purchasing a U2F key.
Once you receive your key, you can start Part two: Add two-factor to your TMU account.
If you’re using an OTV code generator
One-time verification (OTV) code generators are small devices that provide authentication codes for two-factor logins.
Available only to TMU employees, you can check with your faculty or department for approval purchasing an OTV code generator from CCS for $30. They can be requested using the One-Time Verification (OTV) Code Generator Request Form on the CCS website.
Once you receive your key, you can start Part two: Add two-factor to your TMU account.

Backup codes are one-time-use codes you can enter if you’re unable to access your mobile device, or if it’s lost or stolen. We recommend printing or writing down these codes and keeping them in a safe place where you can easily retrieve them when needed.
You’re all set! Now you can log in to your TMU account and provide verification codes whenever asked. Remember—don’t delete Google Authenticator as you’ll need it each time you’re asked for a code.
