A cryptographically secure password generator that runs entirely in your browser. Set the length (4–128 characters), pick your character mix, and generate up to 100 passwords in one click. Works offline — no account, no tracking, and your passwords are never sent to any server.
Set the password length in the generator
Drag the slider or type a number between 4 and 128. Longer passwords are exponentially harder to crack — 16 or more characters is recommended for most accounts.
Choose character types
Toggle uppercase (A-Z), lowercase (a-z), digits (0-9) and symbols (!@#$). The more character types you include, the higher the entropy and the stronger the password.
Apply optional settings
Enable Exclude similar characters to remove confusable pairs like 0/O and 1/l — useful when you need to read or type the password manually. Add custom exclusions if a service forbids certain characters.
Generate and copy your password
Click Generate or press Enter — up to 100 passwords appear instantly. Click the copy icon next to any password, use Copy All, or download the list as TXT, CSV or JSON.
Yes. All passwords are generated locally using the Web Crypto API (window.crypto.getRandomValues) — a cryptographic API built into your browser. No network request is made and your passwords are never sent to any server.
At least 12 characters, ideally 16 or more. A 16-character password using all character types provides over 80 bits of entropy — strong enough to resist all practical brute-force attacks. Each additional character multiplies the search space significantly.
Entropy measures how unpredictable a password is, expressed in bits. 40 bits is weak, 60 bits is fair, 80 bits is strong and 100+ bits is very strong. It is calculated from password length multiplied by the log₂ of the character set size.
Yes. Use the Count slider to generate up to 100 passwords in a single click. Download the entire list as TXT for scripts, CSV for spreadsheets or JSON for programmatic use.
It removes characters that look alike in many fonts: 0 and O, 1 and l and I. Enable it when you need to read the password aloud or type it manually on a device where copy-paste is not available.
