Why the 20-character preset

With symbols and ambiguous exclusion you land near ~100 bits — solid for important accounts. Length and charset are editable below; full controls also live on the password generator.

FAQ

How strong is enough?

≈80 bits covers typical online attacks; 100+ helps if hashes leak offline. Defaults target that range.

vs 16 characters?

Entropy scales with length for the same charset. Prefer 20 when the site allows; use 16-character when capped.

Sent to a server?

No — crypto.getRandomValues only, in this browser.

Password manager?

Yes. Save there and close this tab after copying.
