Strong random password generator
Create hard-to-guess passwords or easy-to-remember passphrases in one click. Adjust the length, choose which character types to include, and avoid look-alike characters if you’ll be typing the password by hand. The strength meter estimates entropy in bits so you can see how tough your password really is.
Tips
- Use at least 16 characters, or a 4–5 word passphrase.
- Use a unique password for every account, stored in a password manager.
- Length beats complexity — a longer passphrase is both stronger and easier to remember.
Frequently asked questions
Are the passwords generated safely?
Yes. They are created in your browser using the Web Crypto secure random generator (crypto.getRandomValues). Nothing is transmitted to us or stored anywhere.
What makes a strong password?
Length and randomness. Aim for at least 16 random characters, or a passphrase of 4–5 random words. The entropy meter shows the strength in bits — higher is better.
What is a passphrase?
A password made of several random words, like “river-maple-quiet-42”. Passphrases are easy to remember and very strong when the words are truly random.
