What Is a Password Strength Checker?
Password Strength Checker estimates how hard a password would be to guess.
This tool runs entirely in your browser. It does not send the password anywhere.
What the Tool Checks
| Check | Why It Matters |
|---|---|
| Length | Longer passwords and passphrases increase the number of possible guesses dramatically. |
| Character variety | Lowercase, uppercase, numbers, and symbols increase the search space. |
| Common patterns | Dictionary words, keyboard sequences, repeated characters, and common passwords are easier to crack. |
| Entropy estimate | Entropy gives a rough measure of unpredictability in bits. |
| Crack time estimate | The displayed time estimates offline guessing against a slow password hash. |
How to Improve Password Strength
Use a long passphrase or a password manager generated value. Avoid names, birthdays, product names, keyboard walks such as qwerty, repeated chunks, and passwords reused across sites.
For important accounts, pair a strong unique password with multi-factor authentication.
Frequently Asked Questions
Length matters most, followed by character variety and avoiding predictable words, keyboard sequences, repeated characters, and known common passwords.
No. Crack time is an estimate based on offline guessing speed and password entropy. Treat it as a comparison guide, not a guarantee.
