How to create a strong password

Short answer

Make passwords long and unique for every account. Length matters more than special characters, so a long random passphrase or a string from a password manager beats a short, clever one. Never reuse passwords across sites.

Length is the biggest lever

Every extra character multiplies the number of possibilities an attacker must try. A long password is far harder to crack than a short one with a few symbols swapped in. Aim for at least 16 characters where the site allows it.

What actually makes a password strong

  • Length: longer is stronger, more than any single trick
  • Randomness: avoid names, dates, and dictionary words
  • Uniqueness: a different password for every account
  • Unpredictability: skip obvious substitutions like P@ssw0rd

Reuse is the real dangerIf one site is breached and you reused that password, every account with it is exposed. Unique passwords contain the damage to a single site.

Use a password manager

You cannot memorize a unique long password for every account, and you should not try. A password manager generates and stores them, so you only remember one strong master password. Turn on two-factor authentication wherever it is offered for an extra layer.

Questions

Are special characters required for a strong password?

They help, but length matters more. A long random passphrase can be stronger than a short password full of symbols. Use both length and variety when you can.

How often should I change my passwords?

Change a password when there is a reason, such as a breach or a shared device, rather than on a fixed schedule. Forced frequent changes often lead to weaker, predictable passwords.

Does the password generator send passwords anywhere?

No. Passwords are generated locally in your browser using the crypto API and are never uploaded or stored.
