Password Generator
Free strong password generator. Create secure random passwords up to 64 characters with letters, numbers and symbols. Uses crypto-grade randomness, runs entirely in your browser.
About the Password Generator
This generator creates truly random passwords using your browser's crypto.getRandomValues() — the same cryptographic-quality randomness used for encryption keys — then removes any modulo bias with rejection sampling. Nothing is stored, logged or sent over the network; every password exists only in the tab you are looking at.
What makes a password strong?
Strength comes from length + randomness, not clever substitutions. A 16-character random password carries roughly 100 bits of entropy — beyond what any realistic brute-force attack can crack. The strength bar shows the estimated entropy of your current settings.
Never reuse passwords across sites: when one site is breached, attackers immediately try those credentials everywhere else. Pair a generated password with a password manager, and turn on two-factor authentication wherever it is offered.
Frequently asked questions
Is it safe to generate passwords online?
This generator runs 100% in your browser with no server calls, no cookies and no logging. The randomness comes from the browser’s built-in cryptographic source. For extra caution, you can even disconnect from the internet after the page loads — it keeps working.
How long should my password be?
Use at least 12 characters; 16 or more is recommended for anything important like email, banking or password-manager master passwords. Length increases strength faster than adding symbol types.
Why exclude ambiguous characters?
Removing look-alikes (0 vs O, 1 vs l vs I) helps when a password must be read aloud or typed from paper. It slightly reduces entropy, so only enable it when you need it.
Are random passwords better than passphrases?
Both work if they are long and random. A random password packs more unpredictability per character; a passphrase like "correct-horse-battery-staple" is easier to remember. The enemy of both is reusing them across sites.
