With the Nuki app you can share access permissions with your family and friends. Just send them invitation codes with your Nuki app, e.g. via text message or email.
To generate an invitation code, tap on the desired Smart Lock in the Nuki app and enter the lock settings. Then go to "Manage users" and choose “Invite user”. By creating the invitation Nuki generates an invitation code which you can share with the invited person.
Invitation codes can only be redeemed once within 48 hours.
To manage users, tap on the desired Smart Lock in the Nuki app and enter the lock settings. Then go to "Manage users". Then you can see the already authorized users and you can edit them, or invite new people to access your Smart Lock.
To invite persons to your Nuki in an instant, you can also open the menu (top left) and choose "Invite person".
