Password Check

Your new password will need to be at least nine characters long (with a maximum length of fourteen characters) and should look like a random string of characters. It must include at least one digit, and a mixture of upper and lower case letters.

Please note that all Cardiff University systems recognise case sensitivity in passwords, so upper-case "A" is not the same as lower case "a" in a password.

You will not be able to reuse previous passwords.

Your password must not include any of the following: your first name, last name, full name, email address, user ID

A list of common passwords which are prohibited is available to view. Passwords may not match or contain any of these passwords.
