Why system cannot create a login and sign up page, I néed to create a app like grab or uber. Pls assist
Because we don’t have our own authentication mechanism, you need to use either Google, Office365, Dropbox, Box, Smartsheet or Salesforce.

Using other auth service, such as AWG Cognito, you can achieve your goal to get the custom login window, however, you will lose the benefit of OpenID log in system.
This is screenshot from one of my Appsheet app where I have AWS Cognito log in system is in place.
