If you have more than one email address, you may want to add both to your Teamup user account. You can do that by adding secondary email addresses, which will be linked to your user account and share the same password.
🛑 This feature should not be used to share the calendar and user accounts should not be shared for security reasons.
In the Email section, select Remove beside the secondary email address:
Remove your primary email address
Perhaps your primary email address is outdated, and you need to remove it. First, you need to make it a secondary email address. Then you can remove it as shown above.
