Secure Password Generator
Generate strong, secure random passwords with customizable length, character types, and strength meter. Cryptographically secure. No server uploads.
Why use a Secure Password Generator?
Human-generated passwords are typically weak, predictable, and vulnerable to dictionary attacks. A secure password generator creates cryptographically random passwords that are resistant to brute force and dictionary attacks. Our generator uses the browser's crypto.getRandomValues() API for true cryptographic randomness, ensuring your passwords are genuinely unpredictable.
Key Features
- Adjustable password length from 8 to 128 characters
- Customizable character types: uppercase, lowercase, numbers, symbols
- Exclude ambiguous characters option and password strength meter
How to use
- Set your desired password length and character types
- Click Generate to create a secure random password
- Copy the password and use it for your accounts
Technical Details
Our password generator uses crypto.getRandomValues(), which provides cryptographically secure random numbers from the operating system's entropy source. This is far more secure than Math.random(), which is not suitable for security purposes. The strength meter evaluates password entropy based on length and character pool size.
FAQ
How long should my password be?
We recommend at least 16 characters for strong security. With a mix of uppercase, lowercase, numbers, and symbols, a 16-character password has approximately 95 bits of entropy.
Are these passwords truly random?
Yes, we use crypto.getRandomValues() which provides cryptographic-quality randomness from your operating system's secure random number generator.
