This is handled with PLC code.

Unitronics has a password screen object which hashes the input value, but this limits you to one password only.  I typically don't use the hashed input so I can have a backdoor password as well as a user-changeable password.

Try your hand at HMI calls based on compare blocks in the PLC logic and post your code with what you've done so we can help.
