Strong Password Generator

A strong password is long, random, and unique. It should not contain names, dates, quotes, keyboard patterns, reused words, or small substitutions that attackers can predict.

Strong password checklist

• Choose enough length: 16 characters is a practical minimum, and 20 or more is better for sensitive accounts.
• Use randomness from the browser crypto API rather than a phrase you invented.
• Keep each account unique so one breach does not unlock other services.
• Prefer a password manager for storage and autofill.

Password or passphrase?

Use a random password when a password manager will store it. Use a multi-word random passphrase when you need to type or remember the secret manually, such as a master password or device login.

Security tradeoffs

Symbols can help, but length is usually easier to reason about. A longer password from a broad character set creates a larger search space than a short password with one symbol added at the end.
