To login to Google Drive, you will use your UT email and password. If you receive an error message referencing permissions, then you are logged into Google using a personal account and will need to log out of that account and then log in with your UT email and password.
To logout of a Google account, go to google.com and look in the upper right corner. You will see a circle with either a letter or an icon. Click that circle and then click sign out. Then you can click the link below and login using your UT email and password.
If you use an alias email address, you will need to login using your official UT email and not the alias.
