Reused and weak passwords are behind most account breaches. This generator creates strong, random passwords in your browser, with full control over length and character types.
Why randomness matters
Humans are predictable — we pick words, dates and patterns that attackers' tools try first. A truly random password from a large character set removes those shortcuts, forcing an attacker to brute-force the entire space.
Length beats complexity
Adding a single character multiplies the number of possible passwords far more than swapping one letter for a symbol. That's why a long passphrase can be stronger than a short jumble — and why the length slider is the most important control here.
Frequently asked questions
Yes. They're generated locally using your browser's cryptographically secure random generator, and nothing is transmitted or stored. For maximum safety, save them in a password manager.
Length above all, plus a mix of character types. A longer password from a larger character set has more 'entropy', making it exponentially harder to guess or brute-force.
At least 12–16 characters for important accounts. The strength meter here reflects the entropy of your chosen length and character sets.
