SMS and phone call Two Factor Authentication (2FA) are being phased out for employees. Employees who don't have a mobile phone or tablet, or would prefer an alternate option, can request a token using the 2FA token request form.
Waterloo students may purchase a U2F key from an external provider, such as Amazon, for personal use, if desired.
If you need to remove a device or replace a phone that was lost or stolen, please refer to the article Removing a device or replacing a lost or stolen token

Optional: You may choose to purchase a token to have a backup should you not have access to your mobile phone or your device of choice.

Optional: You may add multiple Duo Mobile devices to your 2FA account. The Duo Mobile app is available for recent Android (phone, tablet) and iOS (iPhone, iPad) devices. Duo Mobile can also be installed and set up on Chromebooks.
