Please note that a separate QR code will be created for each team in the event (see video). You can also use this to log in on your or other devices.
The team-specific QR code, also known as an account-specific QR code, makes it easier to log in on your devices and to pass on existing access data or team accounts to third parties.
You do not need to use any email data or passwords to log in to the app or send them to third parties. Simply scan the QR code and you will be logged into the event with the linked player/team.
The use cases for this are manifold.
