What is a Password Generator?
A password generator creates random, unpredictable passwords that are far more secure than anything a person would choose manually. Strong passwords use a mix of uppercase letters, lowercase letters, numbers, and special symbols, and are long enough to resist brute-force attacks. This tool generates them instantly in your browser — nothing is sent to a server.
What Makes a Strong Password?
Length
Longer passwords are exponentially harder to crack. Aim for at least 16 characters for accounts you care about.
Uppercase Letters (A-Z)
Adding uppercase letters increases the character set, making each position in the password harder to guess.
Numbers (0-9)
Including digits adds another layer of complexity and is required by most modern password policies.
Symbols (!@#$%...)
Special characters dramatically increase password entropy and are the hardest for attackers to brute force.
Frequently Asked Questions
How long should my password be?
Security experts recommend at least 12–16 characters for most accounts. For critical accounts like banking or email, use 20+ characters with all character types enabled.
Is this password generator secure?
Yes. Passwords are generated entirely in your browser using JavaScript's Math.random(). Nothing is transmitted to or stored on any server.
Should I use all character types?
Yes, enabling uppercase, lowercase, numbers, and symbols gives you the strongest possible passwords. Only disable character types if a specific service restricts them.
How do I remember a generated password?
You should not try to memorize randomly generated passwords. Use a password manager like Bitwarden, 1Password, or KeePass to store them securely.
Can I use this for WiFi passwords, API keys, and tokens?
Yes. This generator is suitable for any use case that requires a random string — passwords, secret keys, API tokens, passphrases, and more.
