Frequently Asked Questions
How secure are the generated passwords?
Extremely secure. They are generated using the browser’s cryptographically secure pseudo-random number generator (CSPRNG) via window.crypto.
Are generated passwords saved on your server?
Never. Passwords exist solely in temporary browser memory and disappear the moment you close or refresh the page.
What makes a password strong against hackers?
Length and character entropy. A 16+ character password mixing letters, digits, and symbols would take modern supercomputers billions of years to crack.
Can I choose to exclude ambiguous characters like I, l, 1, O, 0?
Yes, excluding visually similar characters prevents transcription errors when typing passwords manually on keyboards.
Privacy Guarantee
Passwords are generated strictly in memory using window.crypto. Zero network transmission.
