Password Generator
Choose a length and the character sets you need, then generate one candidate or a list. Every character is drawn with rejection sampling from the browser cryptographic random source, and the entropy shown is the real keyspace of the pool you configured — not a marketing strength bar. Ambiguous pairs such as 1, l and I can be excluded.
A copied password stays in your system clipboard, where other programs on the machine can read it. Clear the clipboard after using it, especially on shared devices.
How to use
Passwords with measurable entropy, drawn from the character sets you pick. Your data is processed only inside this browser tab.
FAQ
Why rejection sampling?
Taking the modulo of a random byte biases a short pool: some characters would appear more often than others and the true entropy would fall below the printed number.
Is anything stored or sent?
No. Generation runs in this page, nothing is written to storage and no request is made — which is also why you should not reuse a password you pasted anywhere.
