1.1 User Login

When a user logs in, the login account can be a mobile phone number or email address (based on the registered account). The login is successful only when the username and password entered match.

1.2 Apply Trail

Users can register via mobile phone number or email address in the website. Can only apply for a trial within the app, as shown in the figure below.

1.3 Retrieve Password

When the user forgets the login password, he can touch the [Forgot password] button and retrieve it through "mobile phone number or email address". Retrieve can only be successfully when the "verification code entered" and the "verification code received by the user on the mobile phone or in the email address" are consistent and the entered password is valid, as shown in the figure below.
