Secure Password Generator: Create Strong Random Passwords
Using strong, unique passwords is the single most important step you can take to protect your online accounts. Our free password generator creates cryptographically secure random passwords using your browser's built-in crypto.getRandomValues() function, ensuring true randomness that cannot be predicted or reproduced.
You can customize your passwords by selecting the character types to include: uppercase letters (A-Z), lowercase letters (a-z), numbers (0-9), and special symbols (!@#$%^&*). You can also adjust the password length from 4 to 128 characters. Security experts recommend passwords of at least 12-16 characters with all character types enabled for maximum protection.
A 16-character password using all character types has approximately 95^16 possible combinations, which is over 4.4 x 10^31 possibilities. Even at a rate of a trillion guesses per second, it would take billions of years to crack such a password through brute force. This is why length and character diversity are the two most important factors in password strength.
Remember that each of your accounts should have a unique password. Reusing passwords means that a breach of one service exposes all your accounts. Use this generator to create a different strong password for each service, and store them in a reputable password manager like Bitwarden, 1Password, or KeePass. You can also verify your password's integrity with our hash generator, or share login credentials securely using a QR code.
