About Strong Password Generator
Password strength depends far more on length than on character variety: a twenty-character lowercase passphrase resists attack far better than eight characters full of symbols. This tool draws from the browser own cryptographic random number generator.

Frequently asked questions
Is the password genuinely random?
Yes. It uses the browser crypto.getRandomValues interface, designed for cryptographic use, rather than the predictable Math.random function.
Is the generated password recorded anywhere?
No. Generation happens entirely in your browser, nothing is sent to a server and nothing is stored. Closing the page discards it.
How often should I change passwords?
Current guidance is that forced periodic rotation does not help and pushes people toward weaker passwords. A long unique password per service plus two-factor authentication works better. Change immediately only after a breach.
