Free Password Generator
Strong, random passwords made entirely in your browser. Adjust length and character types, then copy — nothing ever leaves your device.

Select at least one character type above.
Privacy: this password is generated locally on your device using your browser's crypto.getRandomValues() API. It is never sent to any server — not by this site, not by analytics, not by anyone. Reloading or closing this page discards it for good unless you copy it somewhere safe.
Why length beats complexity
A password's real strength comes from how many guesses an attacker needs before finding it, which is mostly a function of length and how many possible characters could appear at each position. Adding a single extra character to a random password multiplies the guessing work far more than swapping in a symbol or two. That's why a random 16-character password is typically far stronger than an 8-character one stuffed with punctuation.
This generator uses your browser's cryptographically secure random number generator — the same class of randomness used for encryption keys — rather than an ordinary pseudo-random function, so the output is not predictable from the settings you chose.
A few practical tips
- Use a unique password for every account. Reused passwords are the single biggest reason breaches spread.
- Longer is usually better than "clever." Aim for 16+ characters for normal accounts, 20+ for anything sensitive.
- If a site rejects a generated password, try the exclude-ambiguous option or turn off symbols rather than shortening the length.
- A generated password is only as useful as where you keep it — a sticky note or plain-text file defeats the purpose.
Password generator FAQ
Yes. Every password is generated locally in your browser using the Web Crypto API's cryptographically secure random number generator. Nothing is transmitted over the network, so there is nothing to intercept.
No. This tool never sends a generated password anywhere, never logs it, and never stores it. Closing or reloading the page discards it permanently unless you copy it somewhere safe first.
Length matters most. Each extra character multiplies the number of guesses an attacker needs, so a longer password with fewer character types is often stronger than a short one stuffed with symbols. Mixing uppercase, lowercase, numbers and symbols adds further strength on top of length.
General security guidance points to at least 12 to 16 characters for most accounts, and 20 or more for high-value accounts like your primary email, banking, or your password manager's master password.
Symbols increase strength, but a longer password without symbols is usually stronger than a short one with them. Some sites reject certain symbols — if a generated password gets rejected, try again with symbols off or the ambiguous-character filter on.
Use a password manager rather than a note, spreadsheet, or your memory. See our comparison of free password managers for genuinely free options like Bitwarden and KeePassXC.
