Formula & explanation
Passwords are generated with the browser's cryptographic random generator (crypto.getRandomValues), never with Math.random.
Entropy measures how hard a password is to guess: 60+ bits is good, 80+ bits is strong, 100+ bits is excellent.

Is the password stored anywhere?
No. It exists only on your screen until you copy it.
How long should a password be?
At least 12 characters with all character types; 16+ for important accounts.
What are ambiguous characters?
Characters that look alike, such as 0/O or l/1/I. Avoid them if you will type the password by hand.
