About Password Generator
The Password Generator creates strong, cryptographically random passwords for accounts, API keys, database credentials, Wi-Fi passphrases, or any situation that needs a hard-to-guess secret. Choose your desired length, toggle the character sets to include (uppercase letters, lowercase letters, numbers, and special characters), and generate instantly.
Passwords are generated using the Web Crypto API - your browser's built-in cryptographic random number generator. This is not the same as a basic JavaScript Math.random() function, which is predictable and unsuitable for security purposes. Web Crypto generates genuinely unpredictable values, the same standard used for cryptographic key generation. Nothing is sent to a server at any point.
How to use: set the length (16 characters minimum for important accounts - 20 or more is better), enable the character sets you want, and click Generate. Copy with one click and paste directly into your password manager or account creation form. Generate multiple passwords at once if you want options to choose from.
The strength indicator shows the password's entropy in bits and its estimated resistance to brute-force attacks based on length and character set size. A 20-character password using all four character sets has entropy well above 128 bits - effectively unbreakable by brute force with current computing resources.
Best practice: use a unique password for every account and store them in a password manager (1Password, Bitwarden, or your browser's built-in manager). Reusing passwords means that one breach at one service exposes every account that shares it. This generator makes creating and storing unique passwords fast enough that there is no practical reason to reuse them.
