Password Check

A strong password helps to keep your data and information secure. The password strength testing tool on this page will allow you to test new passwords, and check that they are strong enough before you actually use them. Just enter your proposed new password into the "password" field below, and a "score" will be generated, ranging from 0% to 100%.

By using a mixture of letters, numbers and symbols, you can create a password that is easy for you to remember, but more difficult for anyone else to guess.

Your password does not need to score exactly 100%, but aim for as high a score as you can. The score will change as you type (or change) each character.

If you untick the "Hide" check-box, you will be able to see your password on screen - but please ensure that no-one else can read your screen!

This web page does not record or store passwords. JavaScript must be enabled in your web browser for this page to work.
