Generate cryptographically secure random passwords. Customize length and character sets — uppercase, lowercase, numbers, and symbols. Includes password strength indicator.
A password generator creates strong, random passwords using cryptographically secure random number generation. Weak passwords are the leading cause of security breaches, and our tool helps you create passwords that are virtually impossible to crack. Using the Web Crypto API built into your browser, it generates truly random character combinations with customizable length and character sets. Since the password generation happens entirely in your browser using cryptographic randomness, no password is ever transmitted over the network or stored anywhere.
Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the gold standard for random generation in browsers.
A strong password is long (16+ characters) and uses a mix of uppercase, lowercase, numbers, and symbols. Our strength indicator measures entropy — the randomness and unpredictability of the password.
Absolutely not. Passwords are generated entirely in your browser and are never transmitted or stored anywhere. We have no way to see your passwords.
This removes characters that look similar in certain fonts: lowercase 'l', number '1', uppercase 'I', uppercase 'O', and number '0'. Useful for passwords you might need to read or type manually.
