About Password Generator

Generate strong, unpredictable passwords tailored to any security requirement. Powered exclusively by the browser's native Web Crypto API (`crypto.getRandomValues()`) for true cryptographic randomness.

Frequently Asked Questions

Why is crypto.getRandomValues() safer than Math.random()?

Math.random() is a pseudo-random generator with a predictable mathematical seed. In contrast, crypto.getRandomValues() accesses the operating system's cryptographic hardware entropy pool, making outputs mathematically unpredictable.

Are generated passwords saved in history or logged?

Never. Generated credentials exist solely in your volatile browser memory and are discarded as soon as the page is refreshed or closed.
