What makes a strong password in 2026 — and what doesn't

What makes a strong password in 2026 — and what doesn't

If you still believe that adding a number and an exclamation mark to your dog's name makes a strong password, this guide is for you. Modern guidance is simpler than the old rules, and a lot harder to crack.

The new rules, in one sentence

Length beats complexity. A 16-character random string is dramatically harder to crack than an 8-character "P@ssw0rd!" — and easier to generate.

Why the old rules are dead

For two decades, security advice told us to mix uppercase, lowercase, numbers and symbols. The result was predictable: people picked Password1! and reused it everywhere. Attackers learned the patterns faster than humans could invent them.

The 2024 update to NIST SP 800-63B formalised what researchers had been saying for years: focus on length, screen against known breached passwords, and stop forcing periodic changes that lead to weaker passwords.

Three things to do today

1. Use a password manager

A password manager lets every account have a unique 20-character random password without you needing to remember any of them. Pick any reputable manager and turn it on.

2. Generate, don't invent

Use a generator — like the one on this site — to create random passwords. Our Password Generator runs entirely in your browser, so the password is never transmitted anywhere.

3. Enable two-factor authentication

For your email, your bank and any account that touches money, turn on 2FA. Hardware security keys are the strongest option; authenticator apps are a great second choice.

How long is long enough?

  • 12 characters: minimum for low-risk accounts.
  • 16 characters: a good default for everything.
  • 20+ characters: for email, banking and password-manager master passwords.

Common myths

"I have to change my passwords every 90 days." — No. Change them when there is a sign of compromise.
"Adding a symbol makes any password strong." — No. P@ssw0rd! is one of the first guesses attackers try.
