Most account breaches trace back to weak or reused passwords. Fixing that is the single highest-impact security step you can take.
The most important factor in password strength is length, not a clever mix of symbols. Each additional character multiplies the time needed to crack a password. A long passphrase or a 16+ character random string is far stronger than a short password packed with special characters. Generate one instantly with our password generator, which uses the cryptographically secure Web Crypto API.
When one site is breached, attackers try the leaked email-and-password combination on every other major service. This "credential stuffing" is why reuse is so dangerous — one breach becomes many. A unique password per account contains the damage to a single site.
You cannot memorize a hundred unique 16-character passwords, and you should not try. A reputable password manager like Bitwarden, 1Password, or Dashlane generates, stores, and fills them for you. You only need to remember one strong master password.
Curious how strong a password really is? Run it through our password strength checker — it analyzes length, variety, and common patterns entirely in your browser, so the password is never transmitted. For numeric codes like phone or card PINs, the PIN generator avoids predictable choices like 1234 or birth years.
Even a strong password can be phished or leaked. Two-factor authentication adds a second step — usually a code from an app — so a stolen password alone is not enough to get in. Turn it on for email, banking, and any account that supports it.
Good services never store your actual password; they store a one-way hash of it. Our hash generator lets you see how SHA-256 hashing works. Note that for password storage specifically, dedicated algorithms like bcrypt or Argon2 are preferred because they are deliberately slow and salted.
