Passwords, PINs and passphrases

Passwords and PINs are used to identify who you are. Sometimes they are the only defence to protect your information against unauthorised access.

They are the first line of defence to protect your information from cyber criminals. They should be a secret that only you know.

Weak passwords are easy for cybercriminals to guess. They use automated software that can potentially guess 350 billion passwords per second!

If your password or PIN is captured, guessed or stolen, a cybercriminal can potentially:

  • send emails from your accounts
  • withdraw money from your bank accounts
  • change files on your computer such as invoices
  • steal your identity.
