To link your Brilliant Smart account to Google, open Google Home and tap 'add device', 'works with Google', and then search the 'Brilliant Smart' Skill.
Although Google can accept either a phone number OR email address, it is important that you enter your Brilliant Smart email address and the correct password. If you need to confirm which email you used for your Brilliant Smart account, open Brilliant Smart and tap “Me” in the bottom right, tap your account name at the top of the screen, then tap “account and security” and this will display your email address – this is what you need to enter into Google.
If the password is incorrect or you have forgotten it, please log out of Brilliant Smart then use the reset password link to reset your password, once you have changed your password you can enter the new details in Google Home to link the skill.
