Passwords nobody can guess
Length beats complexity: a random 20-character password would take longer than the age of the universe to brute-force. Each one here comes from your browser's cryptographic random generator.
Look-alike characters (l, 1, O, 0) are excluded by default so passwords are easy to type.

Frequently asked questions
Are these passwords stored anywhere?
No. They're generated on your device and disappear when you leave the page.
What does bits of entropy mean?
It measures unpredictability. 70+ bits is strong; 100+ is excellent.
How often should I change passwords?
Only when there's a reason, like a breach. Unique passwords per site matter far more.
