What is a Password Generator?
What is a Password Generator?
A password generator creates strong, random passwords using cryptographically secure random number generation. These passwords are virtually impossible to guess and protect against brute-force attacks, dictionary attacks, and social engineering attempts.
- True Randomness: Uses cryptographic algorithms for unpredictability
- Customizable: Choose length, characters, and complexity
- Secure by Default: Generates passwords meeting security best practices
- Private: Generated entirely in your browser
Why Use a Password Generator?
Human-created passwords are predictable and weak. People tend to use common words, dates, and patterns that hackers can easily guess. A password generator creates truly random combinations that are resistant to all common attack methods. Plus, our tool runs 100% in your browser, so your passwords are never sent over the internet.
How to Use
- Choose a preset or customize settings below
- Set your desired password length (12+ recommended)
- Select character types to include
- Optionally enter a keyword to incorporate
- Click Generate to create passwords
- Click copy icon or generate QR code to use the password
💡 Pro Tips
- Use at least 12 characters for better security
- Mix lowercase, uppercase, numbers, and symbols
- Avoid common words or predictable patterns
- Use unique passwords for each important account
- Consider using a password manager to store passwords securely
- Enable two-factor authentication whenever possible
Password Security Glossary
- Entropy
- A measure of password randomness and unpredictability. Higher entropy means stronger passwords.
- Brute Force Attack
- Trying every possible password combination until finding the correct one.
- Dictionary Attack
- Using lists of common words and passwords to guess credentials.
- Character Set
- The pool of characters available for password generation (letters, numbers, symbols).
- Password Strength
- How resistant a password is to guessing and cracking attempts.
- Cryptographically Secure
- Random generation method suitable for security purposes, unpredictable by attackers.
- Rainbow Table
- A precomputed table of password hashes used to crack passwords quickly.
- Two-Factor Authentication
- Security method requiring two forms of verification, adding protection beyond passwords.
