How to Use Password Generator
To generate a strong password, set your desired length using the slider, then choose which character types to include: uppercase letters, lowercase letters, numbers, and symbols. Click Generate and a cryptographically random password is created instantly. You can generate as many passwords as you need until you find one you like.
The strength indicator shows whether the generated password is weak, fair, strong, or very strong based on its length and character variety. Click the copy icon to copy the password to your clipboard. For maximum security, passwords of 16 or more characters mixing all four character types are recommended.
Frequently Asked Questions
How secure is the generated password? expand_more
Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness. This is the same standard used in professional security tools.
What makes a password strong? expand_more
Password strength depends on length and character variety. A strong password is at least 12 characters and includes a mix of uppercase letters, lowercase letters, numbers, and symbols, making it resistant to brute-force attacks.
Is my generated password stored or logged? expand_more
No. Passwords are generated entirely in your browser using JavaScript. Nothing is sent to any server, so no password is ever stored or logged.
What is the difference between a password and a passphrase? expand_more
A passphrase is a sequence of random words (e.g. 'correct horse battery staple') that is long and memorable. A password is typically a shorter string of mixed characters. Both can be very secure when they are long and random.
How long should a secure password be? expand_more
Security experts recommend at least 12–16 characters for most accounts. For highly sensitive accounts such as email or banking, 20 or more characters provides an extra safety margin.
