Users can change the email address associated with their Quickbase account from their profile. Account admins, realm admins, and app managers cannot update this information on a user’s behalf.
To change your email address:
Select the user dropdown on the Global bar, then select Profile.
In the My User Information section, enter a new email address.
Select Save.
You’ll be automatically logged out and prompted to verify your new email address in both your old and new email accounts.
