We have made some changes to how passwords are created for admin users. When you create or edit an admin user's password, you will need to meet stricter criteria for the password for be accepted.
A password must be 8 or more characters long. All passwords are also screened against known lists of vulnerable and previously-compromised passwords. These checks are intended to keep your data safe and prevent unauthorised access to your accounts.
In addition, we'd like to remind you of the importance of not reusing passwords between different sites or accounts. We strongly recommend the use of a password manager to generate unique passwords for every site you have a login for. You can find some more tips on generating good passwords here.
