When you are asked to create a password – either for a new online account or resetting login information for an existing account – you’re likely to choose a password you know you can remember. Many people use extremely basic passwords, or a more obscure one they reuse across many sites. Our research has found that others – even ones who use different passwords for each site – have a method of devising them, for instance basing them all on a familiar phrase and making site-specific tweaks.
