Password Generator
Generate strong, secure, random passwords with the Web Crypto API. Choose length (8-64), uppercase, lowercase, numbers, symbols. 100% browser-based, unlimited, no signup.
Cryptographically Secure
Uses the Web Crypto API (`crypto.getRandomValues`) — never Math.random(). Each character is drawn from an unbiased secure RNG with Fisher-Yates shuffle.
100% Private
Your password is generated and displayed entirely in your browser. Nothing is uploaded, logged, or sent to any server. No signup.
Strength Meter
Live entropy-based strength rating (Weak → Very Strong). Tweak length and character sets and watch the strength bar update instantly.
Fully Customizable
Length 8-64, uppercase, lowercase, digits, symbols, exclude ambiguous chars (Il1O0). One click to copy, one click to regenerate.
Is this password generator safe to use?
Yes. Passwords are generated entirely in your browser using `crypto.getRandomValues`, the same cryptographic primitive browsers use for TLS. The password never leaves your device — no network request is made.
Why not Math.random()?
Math.random() is not cryptographically secure — its output can be predicted. The Web Crypto API draws from the operating system CSPRNG, which is unpredictable and suitable for passwords and secrets.
How long should my password be?
Aim for at least 16 characters with all four character sets enabled — that gives ~100 bits of entropy, which is "Very Strong" and resistant to brute force for the foreseeable future.
What does "exclude ambiguous characters" do?
It removes characters that look similar (uppercase I, lowercase l, digit 1, uppercase O, digit 0, lowercase o) so the password is easier to read and type.
Is there a daily limit?
No. Generate as many passwords as you want, any time, on any device. The tool is 100% free with no signup and no limit.
