Password Strength Checker
Description
In an era of constant data breaches, a strong password is your best defense. The Password Strength Checker is a security utility that evaluates the resilience of your passwords against brute-force attacks. It analyzes length, complexity (use of numbers/symbols), and variety to assign a strength score. It also estimates the time it would take a modern computer to crack your password. Best of all, it runs locally in your browser—your password is never sent to our servers, ensuring total privacy.
What It Does
Analyzes password complexity and provides a strength rating along with an estimated time-to-crack.
How To Use
- Enter Password: Type a potential password into the input field.
- Check Meter: Watch the bar change color (Red to Green) as you improve the password.
- Review Criteria: Use the checklist below the bar to see what you are missing (e.g., lowercase, symbols).
Who It Is For
Everyone concerned about their online security, IT admins, and privacy advocates.
Freqently Asked Questions
Is it safe to type my real password?
Yes. The checking logic is written in JavaScript and runs entirely on your device. No data is transmitted over the internet.
What makes a strong password?
Length is key (12+ chars), mixed with variety (A-Z, a-z, 0-9, !@#). Avoid common words or personal dates.
What does "Crack Time" mean?
It is an estimate based on the number of possible combinations. "Centuries" means it is mathematically infeasible for current technology to guess it.
