About this tool
Strong passwords should be long (14+ characters) and mix uppercase, lowercase, digits and symbols. This generator uses your browser's cryptographic random number generator (crypto.getRandomValues), which is far stronger than Math.random(). Generate, check the entropy estimate, and copy — the password never leaves your device.
FAQ
How long should my password be?
16+ characters for important accounts; 64 is overkill but harmless. Length matters more than symbol soup.
Is this password generator safe?
It uses crypto.getRandomValues in your browser — the password is never transmitted or stored.
What is entropy?
Entropy (bits) measures guessing difficulty. 80+ bits is very strong; this tool shows the estimate live.
