If you have access to several Ungapped accounts you do not need to log out and log in to access them. No matter how many accounts you have access to, you only log in once at (www.ungapped.com) using the same login credentials.
Once logged in, you can switch to another account.
How to switch to another account:
Click on your account name at the bottom of the black left menu.
All accounts that you are authorized to access appears in the list.
Find your account in the list, and click on the account name to switch to that account.
