You do not need to manage user id an password service-wise, it is taken care by the SAP system.

Access restriction should be achieved via authorization check.

Storing the password in plain text or the password hash?

User ID has probably a limited length, you then don't need String.

In ABAP tables string type is CLOB.

So to store user name use CHAR with fixed max length.

P.S. is it "legal" to use single user as background user to authentificate with some Z-code ?
