How Long Should Your Password Actually Be in 2026?

"At least 8 characters, one uppercase, one number, one symbol" is the password rule half the internet still enforces, and it's mostly theater. Length beats complexity by a wide margin, and most of those composition rules exist to satisfy an old compliance checklist, not to actually resist cracking.

Why length matters more than character variety

A password's resistance to brute-force guessing comes from its entropy — the number of possible combinations an attacker has to try. Adding one more character to a password multiplies the search space by the size of your character set; adding a symbol requirement to a short password barely moves the needle by comparison.

A 10-character password using only lowercase letters has roughly 26^10 (about 1.4 × 10^14) combinations. An 8-character password mixing upper, lower, digits, and symbols has about 94^8 (about 6 × 10^15) — more, but not dramatically more, and it's far harder to remember. Add two more characters to the simple one and it overtakes the complex one.

The actual guidance for 2026

• Minimum 12 characters for anything that matters — accounts, not throwaway test logins.
• 16+ characters for anything protecting financial data, admin access, or a password manager's master password.
• Character variety is a bonus, not a substitute — a long passphrase beats a short "complex" password against real-world cracking tools.
• Uniqueness matters more than strength — a strong password reused across five sites is only as safe as the weakest of those five when one gets breached.

What actually breaks a "strong" password

Most real-world compromises don't come from brute-forcing a good password — they come from:

• Credential stuffing — reusing a password that leaked in an unrelated breach.
• Phishing — handing the password over directly, regardless of its strength.
• Weak recovery flows — a strong password behind a weak "forgot password" email/SMS reset.

Length and randomness protect against brute-force. They don't protect against reuse or phishing — a password manager and unique passwords per site do.

The Password Generator generates cryptographically random passwords of any length, with an option to exclude ambiguous characters for manual typing. Everything runs locally — nothing generated is sent anywhere.
