I'm learning and writing a mobile application. Now I have a problem with requirement from my boss.
The requirement is: create a login form/page use Hana account. This means to use mobile app we need have a Hana account and login via this account.
Mobile app: "Hello user name".
Hana account: P194xxxxxxxx or email is registered Hana.
If login successful, you can go to mobile app "Hello user name" and use it.
If login fail, return a message "Login fail, wrong user or password".
Could you please give me hints/ideas how to do it ?
I'm very appreciate with your helping.
