Why Trust This Password Generator?
Security starts with trust. Most online password generators create your password on their server and send it to your screen. This means, theoretically, they could log your password. The Open Tools Password Generator runs 100% Client-Side.
When you click "Generate," the math happens right here in your browser using the JavaScript crypto.getRandomValues() method. Your new password never leaves your device. You can even disconnect from the internet and use this tool offline!
What Makes a Password "Strong"?
Hackers use "Brute Force" attacks to guess passwords. They try billions of combinations per second. Here is how to beat them:
- Length is King: A 12-character password takes centuries to crack. An 8-character password takes minutes. We recommend a minimum of 16 characters.
- Entropy (Complexity): Mixing Uppercase, Numbers, and Symbols increases the possible combinations exponentially.
- Unpredictability: Humans are bad at random. We pick "Password123" or "Summer2025". Our tool uses a cryptographically secure random number generator to remove human bias.
Password Security Tips
1. Use a Password Manager: Don't try to remember complex passwords like 9#kL!mP2$v. Use a tool like Bitwarden or 1Password.
2. Enable 2FA: Two-Factor Authentication is your safety net. Even if someone steals your password, they can't get in without your phone.
3. Never Reuse Passwords: If one site gets hacked, attackers will try that same email/password combo on banking sites. Use a unique password for every login.
Frequently Asked Questions
Do you store the generated passwords?
No. We have zero knowledge of what you generate. There is no database connected to this tool.
Why is the maximum length 64?
Most websites and password managers have limits on password length. 64 characters is considered "Overkill" security (taking trillions of years to crack) and is compatible with almost all modern systems.
