Trusted devices are hardware (i.e. smartphones) and software (i.e. web browsers) that can be remembered for your next login. Only accounts secured by 2-Step Verification will have the option to remember the device used during the authentification.
When signing in with one of your trusted devices, you don't need to go through 2-Step Verification again. However, note that you still have to log in with your Ubisoft credentials even if you're using a trusted device.
If you tick the Remember this device box (see picture below) on any Ubisoft login page, the device will be added to your list of trusted devices for your Ubisoft Account.
How can I manage these devices?
After registering a new device from the 2-Steps Verification page on login, you are able to manage your trusted devices from the Security Settings page of the Account Management website. Simply look for the box Manage my trusted devices and click on it to have an overview of which devices are registered.
If you need to access the Account Management website through different locations, we would suggest renaming device names and adding more information (e.g. Work, Home, Smartphone).
