Use puzzle text only
The Password Game is entertainment. It uses the familiar shape of a password field as a puzzle mechanic, but it should never receive a real password, private phrase, account credential, or reused login secret.
Create nonsense strings while you play. If the result happens to look complex, it is still a puzzle answer, not a recommended real-world credential.
Client-side validation helps, but habits matter
The game validates rules in your browser so feedback appears instantly. That design means the puzzle does not need an account or server-side password checker to work.
Even so, the safest rule is universal: do not type sensitive information into games or demos. Use a dedicated password manager to generate and store real passwords for important accounts.
