16
Strong, random passwords generated locally in your browser — nothing is sent to any server.
Pick a length, enable or disable character groups, and exclude any characters that confuse you.
The password is created entirely in your browser using the Crypto API. Nothing leaves your device.
Copy with one click and save it in your password manager. Never reuse passwords across services.
No. All generation happens client-side in your browser using the Web Crypto API. No data is transmitted, logged, or stored anywhere on any server.
We recommend at least 16 characters for most accounts, and 24+ for high-value accounts like email or banking. A longer password is always more secure.
A password manager lets you use a unique, strong password for every service without memorising them. This prevents credential stuffing attacks when one service is breached.
It removes characters that look alike (like 0 and O, or l and 1) from the character pool — handy when you need to type a password manually instead of copy-pasting it.
Entropy measures how unpredictable a password is. The strength indicator on this tool estimates entropy based on length and character pool size. Higher entropy = harder to crack.
