Questions worth answering upfront.

Yes. Every character comes from the browser's cryptographic random source (crypto.getRandomValues) with rejection sampling to avoid bias.

No. Passwords are generated entirely in your browser and never uploaded, stored, or logged. Nothing leaves your machine.

Strength is based on entropy — the password length times the bits per character from your selected character sets — and shown in bits.

It removes easily confused characters (I, l, 1, O, 0, o) so the password is easier to read and type.

Yes. Every tool on DevUtilsNow is free to use with no account required.
