password generator
Generate secure passwords instantly. No browser extensions needed. Customizable length, symbols, numbers. Free forever.
A password generator creates secure, random passwords to protect your online accounts and digital assets. This tool is essential for individuals creating new account passwords, IT administrators setting up user accounts, developers generating test credentials, and anyone who needs strong, unique passwords. By using a password generator, you can create passwords that are difficult to guess or crack, meet security requirements, and protect your sensitive information. The tool uses cryptographically secure random number generation and processes everything in your browser, ensuring your passwords are never transmitted or stored.
What is password generator?
A password generator creates random passwords using a combination of character types: uppercase letters, lowercase letters, numbers, and symbols. The generator uses cryptographically secure random number generation (Web Crypto API) to ensure true randomness, making passwords unpredictable and secure. You can customize password length and character types to meet specific requirements. Strong passwords typically include a mix of all character types and are at least 12 characters long. Longer passwords with more character variety provide better security against brute-force attacks and password cracking attempts.
Common use cases
- Account creation: Generate strong passwords when creating new online accounts or user profiles
- Password updates: Create new secure passwords when updating existing account passwords
- IT administration: Generate initial passwords for new user accounts in organizational systems
- Development testing: Create test credentials for applications, APIs, or development environments
- Security audits: Generate sample passwords for security testing or password policy validation
- Personal security: Create unique passwords for different accounts to prevent credential reuse attacks
Limitations and common mistakes
- Generated passwords are random and cannot be recovered if lost. Always store passwords securely in a password manager
- Very short passwords (under 8 characters) are weak even with all character types and should be avoided
- The strength indicator is a general guide. Actual password security depends on the specific system and attack methods
- Passwords must be stored securely. Never share generated passwords or store them in plain text files
- Some systems may have specific character restrictions that the generator does not account for
