Access Control by Shelly

Totally SUCKS: asks for login information, but no way to create a new account.

Good, works with reliability; only needs sending notification via email or SMS to added users on how to install app and on how to use their granted access. User profile already has user name, phone and email as set by admin, and there should be an option upon starting app for invited users being granted access as setup by admin using Google credentials, biometric app entry and a button for each lock.
