About Random Password Generator
Our free online Random Password Generator creates strong, secure passwords using cryptographically random character selection. You can customize the password length from 8 to 64 characters and choose which character types to include.
Strong passwords are essential for protecting your accounts from unauthorized access. A good password should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and special symbols.
This tool generates passwords entirely in your browser using JavaScript, ensuring that no passwords are ever sent to any server. The exclude similar characters option removes characters like 0, O, I, l, and 1 that can be easily confused when reading.
The auto-generate feature creates new passwords instantly whenever you change any option, making it easy to find the perfect password for your needs. Each generated password includes a strength indicator to help you assess its security level.
