Free Password Generator
Generate strong, random passwords 100% in your browser — nothing is ever sent anywhere.
How to use / FAQ
Set a length and choose which character sets to include — uppercase, lowercase, numbers, and symbols. A new password is generated instantly, and the strength meter estimates how hard it would be to guess based on its length and character variety.
The reason to generate a password rather than invent one is simple: humans are terribly predictable. We pick dictionary words, swap the obvious letters for digits, and append a year — and password-cracking software tries exactly those patterns first, billions of guesses per second against a stolen database. A randomly generated password has no pattern to exploit, so the only attack left is brute force, and at 16+ characters brute force stops being feasible. Generation here uses your browser’s cryptographic random number generator and happens entirely on your device — the password on your screen has never existed anywhere else.
Are these passwords safe to use?
They're created with your browser's cryptographically secure random generator and never leave your device — nothing is sent, logged, or stored anywhere. There is also no way for us (or anyone) to know what was generated: the result exists only on your screen.
How long should my password be?
For important accounts, aim for 16 characters or more with several character sets enabled. Length matters most: each extra character multiplies the number of combinations an attacker would have to try.
What does the strength meter actually measure?
Entropy — the number of possible passwords your settings could produce, expressed in bits. Each additional bit doubles the search space. Length adds bits fastest, which is why a long lowercase-only password can beat a short 'complex' one.
How do I make a stronger password?
Increase the length and enable more character sets. Longer passwords with a mix of upper, lower, numbers, and symbols have far more possible combinations, which the meter reflects.
Is a random password better than a passphrase?
Both are strong if they're long enough and genuinely random. A random 16-character password packs more strength per character; a passphrase of four or five random words is easier to memorise and type. A good rule: use a passphrase for the handful of passwords you must remember (laptop login, password manager), and random generated passwords for everything stored in the manager.
Why not just use a word and swap in numbers, like P@ssw0rd1?
Cracking tools apply those exact substitutions automatically — '@' for 'a', '0' for 'o', a digit or year at the end — so a mutated dictionary word falls in seconds. Randomness is the whole defence: a password you could plausibly think up is one software can plausibly guess.
Should I reuse a generated password?
No — generate a unique one per account and keep them in a password manager. Reusing a password means a single breach can expose every account that shares it: attackers routinely replay leaked email-password pairs against banking, shopping, and social sites.
Do I still need two-factor authentication with a strong password?
Yes. A strong password protects against guessing and cracking, but not against phishing or a site leaking your credentials in plain text. Two-factor authentication means a stolen password alone still isn't enough to sign in — enable it on email and financial accounts first.
