A password is a string of characters used to verify the identity of a user and allow them to gain access to a device, application or website. The problem with passwords is that they're easily forgotten by most people, leading to poor password security hygiene.
We're now encouraging the use of passphrases. As part of our NCSC Certified training, we recommend their best practice advice to use a combination of 3 random words to secure logins. When joined together, this creates a complex high-entropy passphrase that's highly secure, yet more easily memorable to a human being than a string of random characters.
