A sub-user follows the owner login path but must also enter a temporary permission code supplied to the primary account owner.
Log in as a sub-user
From the opening screen, choose Login.
Verify the sub-user's phone number.
Select the Owner role.
Enter the phone number associated with the owner account.
Ask the primary owner for the new permission code or PIN and enter it when prompted.
Why the PIN changes
A fresh PIN is generated when a sub-user logs out or when the primary owner signs out. The previous PIN will not work for the next login.
If every sub-user is suddenly signed out
Signing out the primary owner also signs out the account's sub-users. Each sub-user will need the current permission code from the primary owner to log back in.
