As I login from a new user created through HANA Studio, it asks for Password change.
I'm new to the environment and don't know how to disable this.
This is a system behavior that can be configured either via parameter configuration
( indexserver.ini -> [password policy] -> force_first_password_change )
or
via the Security editor in SAP HANA studio -> "Password Policy" -> [ ] User must change password at first logon.
It's also explained in the Administration Guide documentation (built into the SAP HANA studio help).
