About the Random Password Generator
A Random Password Generator creates unpredictable passwords using a cryptographically secure random generator (the Web Crypto API), not the predictable Math.random. Longer passwords with mixed character types have far more entropy, making them exponentially harder to crack.
Because generation happens entirely in your browser, the password is never sent over the network or logged — it exists only on your device until you copy it. Use a unique password per account and keep them in a password manager.
A Random Password Generator leans entirely on the operating system's entropy pool via crypto.getRandomValues, so the output passes through no seed you could reconstruct or replay — re-running it a million times never reproduces the same string. That non-determinism is exactly why it's the right pick for one-off secrets you'll store in a manager and never type again: master passwords, API keys, database credentials, or per-account fillers during a breach cleanup. Reach for it whenever a value must be unguessable rather than memorable, since a CSPRNG-drawn string has no pattern, dictionary root, or keyboard walk for an attacker to lean on.
Frequently asked questions
Are these passwords secure and random?
Yes. They are generated with the Web Crypto secure random generator in your browser — not the weak Math.random — and nothing is transmitted.
Is the password sent anywhere?
No. It is created entirely in your browser and never uploaded or logged; it exists only on your device.
How long should my password be?
At least 16 characters with mixed types is a strong default; longer is better. The strength meter shows the entropy as you adjust the options.
Can I choose which characters to include?
Yes — toggle uppercase, lowercase, numbers and symbols, and set the length, to match each site’s rules.
Could this generator ever hand two people the exact same password?
It's not literally impossible, but with a CSPRNG drawing from a huge character space the odds are astronomically small — a 16-character mixed password has more combinations than there are atoms in a building, so collisions are effectively never something you'd see in practice.
