the component I want to suggest for this zappl app is a new feature, that is Scan QR Code.
My suggestion for the Zappl app is to add the Scan QR Code feature that makes it easy for app users to sign in without using passwords.
location placement of this feature we can see below by paying attention to the red arrow in the picture
With the "Scan QR code" feature, users can use the feature to sign in to zappl apps, by simply scanning QR code and automatically users can directly log in zappl.
