Passwords that actually protect
Choose length and character sets — get a crypto-random password with entropy bits and strength rating, generated entirely in your browser. Nothing is sent or stored.
Frequently asked questions
Is my password sent to a server?
No — it's generated in your browser with crypto.getRandomValues and never leaves your device.
How long should my password be?
16+ characters with all sets is strong (95+ bits). 12 is the minimum for anything important.
What is entropy?
Bits of unpredictability. 80+ bits resists brute force for centuries. Longer passwords and bigger character sets raise it.
Should I exclude ambiguous characters?
If you'll type it manually (WiFi, TV apps) — yes, 0/O and 1/l/I cause typos. For password managers, keep them.
