Add signup/login to your app

Sign up and verify your email address, then stop the app to return to the editor. (You may have opened the app in a new tab when you verified your email, in which case close that tab, then stop the app in your original tab.)
Click on Data Tables under Services in the App Browser.
You should see a table called Users, containing one row - the user record for the email address you signed up with.
Notice that your password has been hashed by Anvil (using the bcrypt algorithm). This means somebody with access to the data stored within Anvil cannot work out your password. It is the standard best-practice way to store passwords on the web.
Add this line to the end of the
__init__ method in
print('This user has logged in: ' + anvil.users.get_user()['email'])
This will get the logged-in user and print that user’s email address.
Run your app and log in. You will see your email address printed in the Output Panel.
