LocalUsta is currently in beta and all tools are free. Some advanced features may become part of a paid plan in the future; we aim to keep the core tools accessible to everyone.
Terms of Service →Secure Password Generator
Uses cryptographic secure pseudo-random number generator (CSPRNG) to create unpredictable passwords.
Calculates the exact mathematical entropy and pool size of your passwords.
Instantly know how long it would take an attacker (at 10 billion guesses/second) to crack your password.
Powered by Rust and WebAssembly, all generation and analysis happens entirely on your device.
Select your desired password length (minimum of 12-24 characters is highly recommended) and check upper/lowercase letters, numbers, or symbols.
Click 'Generate New Password' or use the refresh icon to instantly produce a cryptographically secure random password (CSPRNG) locally.
Review the instant security analysis report, showing mathematical entropy in bits and estimated crack time assuming an attacker can make 10 billion guesses/second.
Click the copy button to copy the password directly to your system clipboard safely. The entire process runs 100% offline.
Generating passwords on third-party servers exposes you to potential leaks. LocalUsta Password Generator works entirely in your browser using secure random number generation (CSPRNG) via WebAssembly. Your passwords are never sent anywhere.
