Password Strength Checker – Test Your Password Security

Our Password Strength Checker analyzes your password in real time and tells you exactly how secure it is — and how to make it stronger.

What Gets Analyzed

- Length: longer passwords are exponentially harder to crack
- Character variety: uppercase, lowercase, numbers, symbols
- Common patterns: dictionary words, keyboard walks (qwerty), repeated characters
- Common passwords: checked against the most frequently used password lists
- Entropy: mathematical measure of unpredictability in bits

Strength Levels

- Very Weak: cracked in milliseconds
- Weak: cracked in minutes to hours
- Fair: cracked in days to months
- Strong: cracked in years
- Very Strong: effectively uncrackable with modern hardware

Best Practices for Strong Passwords

- Use at least 12 characters (16+ for sensitive accounts)
- Mix uppercase, lowercase, numbers, and symbols
- Avoid real words, names, dates, or keyboard patterns
- Use a password manager to generate and store unique passwords
- Never reuse passwords across multiple sites

Privacy Guarantee

Your password is analyzed entirely in your browser. It is never sent to any server, logged, or stored. The tool cannot see what you type.
