Password Strength Checker
Analyze your password strength and get security recommendations
Check password security, entropy, and time to crack
Language:
Password Input
Enter your password to check its strength
Your password is not stored or transmitted
This password strength checker analyzes your password security without storing or transmitting your password. It provides entropy calculations, time-to-crack estimates, and specific recommendations to improve your password security.
Did You Know?
Password strength checkers use entropy calculations to measure unpredictability - higher entropy means stronger passwords that are harder to crack.
The time-to-crack estimates are based on current computing power and common attack methods, but actual cracking time can vary significantly.
Modern password strength checkers analyze not just character types but also patterns, common substitutions, and dictionary attacks to provide more accurate assessments.
These facts help provide context and educational value about the tool's purpose and history.
