The default screen is a 'create account' form, which requires the user to enter their name, email, password & birthday. All information is required, so if the user tries to submit the form without filling everything in they will be reminded to fill in all of the input fields.
If the user already has an account they have the option to click 'Login Here' which pulls up a login page for returning users. This form only requires the user to enter their email & password to log in.
If the user already has an account, but have forgotten their password, they can click on 'Forgot Password' which asks for the user to enter their email.
*** Results of the form will be submitted *** Endpoint via Form Submit
