Frequently Asked Questions

No, absolutely not. Password strength checking happens locally in your browser. Only password generation requests are sent to our server (without the actual password being transmitted back). Your passwords never leave your device during analysis.

Strong passwords are long (12+ characters), use multiple character types (uppercase, lowercase, numbers, symbols), avoid common patterns, and don't contain personal information. Our tool analyzes entropy, pattern recognition, and dictionary attacks to provide comprehensive strength assessment.

We use the zxcvbn algorithm developed by Dropbox, which goes beyond simple character counting. It analyzes patterns, dictionary words, keyboard sequences, repetition, and estimates time to crack using modern attack methods.

With modern computing power and attack techniques, passwords under 12 characters can be cracked relatively quickly. 12+ characters exponentially increase security by expanding the possible combinations, making brute force attacks harder.

Yes! Our generator uses cryptographically secure random number generation to create truly random passwords. However, we recommend using a password manager to store them securely, as randomly generated passwords are difficult to remember.

Our tool combines advanced analysis (zxcvbn algorithm), complete privacy for checking (client-side processing), educational feedback, and cryptographically secure generation in one comprehensive tool. Plus, it's completely free and open-source.

IMPORTANT: Use a Password Manager

Never reuse passwords! With the complexity of modern passwords, it's impossible to remember unique passwords for every account. Store generated passwords securely using reputable password managers.

Reputable Password Managers Use Trusted Solutions
Don't Save in Browser
Unique Passwords Always

Every account should have its own unique password. If one gets compromised, others remain safe with a password manager.

Enable Two-Factor Auth

Add an extra security layer with 2FA using apps like Google Authenticator, Authy, or hardware security keys.

Monitor & Update

Regularly check for breaches, update compromised passwords immediately, and monitor your accounts for suspicious activity.
