This is another script that requires both a login and password to gain entry to the protected page, with an incorrect set taking the user to a 'failure' page instead.

Keep your visitors from submitting their form until their 'password' and 're-enter password' fields match, for verification purposes. They get an error message telling them to re-enter the passwords if they do not match.

Another method to encode and decode your data with a key value.

Use this script to disable the selection of text on a page. It's very simple using two of the built-in JavaScript events to cancel the selection before it starts. You can even attach the events to a specific element.
