To start using the security feature, just click on the Enable Security check box to enabled the login name and password(s) text box.
Once the login name and password(s) text boxes are enabled, type in the username that you wish to use and type the password twice. Twice to make sure you have the typed the password correctly since you will not be able to see what you typed in.
The UserName is not required, but the password is. If you do not type in a user name, the default "admin" will be used.
Now just incase you forget your password, we now have a "Forgot Password" feature on the login screen. The Forgot Password Phrase and Word fields are required! Type in the Phrase that you wish to use, and the word that is the answer. It doesn't exactly have to be 1 word, you can have the rest of the phrase sentence in the word section. Just as long as it is something that you can remember.
Once you have created the username and password that you wish to use, click on the Save or Apply button to save your changes. Now next time that you run the program it will ask you for a username and password ( see Logging in for more details ).
