3 practical tips
  1. Make it long. Use at least 12 characters — length beats cleverness every time. A passphrase like four random words is both strong and memorable.
  2. Mix character types. Combine lowercase, UPPERCASE, digits and symbols (e.g. !@#?) to multiply the guessing work.
  3. Never reuse or recycle. Avoid common passwords and dictionary words, and never reuse the same password on two sites — use a password manager instead.

🔒 Your password never leaves this page. The check runs 100% in your browser — nothing is sent, stored or logged anywhere.
