Password Generator
Create strong, random passwords with crypto-grade randomness, generated entirely in your browser.
A strong password is long and unpredictable. This generator uses your browser's built-in Web Crypto API to produce truly random passwords, then estimates their strength in bits of entropy, the standard measure of how hard a password is to guess.
Because everything happens locally, the password never travels over the network. Generate one, copy it straight into your password manager, and you're done.
Frequently asked questions
Are these passwords safe to use?
Yes. Passwords are generated locally in your browser using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness. Nothing is transmitted, logged, or stored on any server.
How long should my password be?
For most accounts, 16-20 characters with a mix of character types is strong. Anything above roughly 80 bits of entropy is considered very hard to crack. Use the strength meter as a guide and prefer longer passwords for important accounts.
What does 'exclude look-alike characters' do?
It removes characters that are easy to confuse, like the lowercase L, capital I, the number 1, and the letter O versus zero. That helps when you need to read or type a password manually.
Should I reuse passwords?
No. Use a unique password for every account and store them in a reputable password manager. That way a breach of one service can't compromise the others.
