How does the strength checker work?

The tool analyzes your password against multiple criteria including length, character variety, common patterns, and dictionary words. It estimates how long it would take to crack the password.

Is my password sent to a server?

No. All password analysis happens locally in your browser. Your password never leaves your device and is not stored or transmitted anywhere.

What makes a strong password?

Strong passwords are at least 12 characters long and include uppercase letters, lowercase letters, numbers, and special characters. They avoid dictionary words, common patterns, and personal information.

Does it check against known breached passwords?

The tool checks for common passwords and patterns known to be weak. For comprehensive breach checking, use a service like Have I Been Pwned.

What is the crack time estimate?

The tool estimates how long a brute-force attack would take to guess your password based on its complexity. Times range from instant for weak passwords to centuries for strong ones.
