Frequently Asked Questions
Are passwords generated by this tool truly random and safe?
Yes! We use the browser native Web Crypto API (`window.crypto`), ensuring military-grade cryptographic randomness.
Are generated passwords saved or logged anywhere?
Never. Passwords exist only in temporary browser RAM memory and disappear when tab closes.
What makes a password strong against hacker attacks?
A password over 16 characters mixing numbers, symbols, and mixed-case letters yields over 90+ bits of entropy, taking centuries to brute-force.
Can I generate memorable passphrase words?
Yes, passphrase mode generates combinations of random dictionary words separated by hyphens.
