Password Strength Checker: How Secure Is Your Password?
Test any password to see how strong it is. Get a strength score, estimated crack time, and specific suggestions for improvement.
What It Does
The Password Strength Checker analyzes a password and rates its strength from very weak to very strong. It estimates how long the password would take to crack using brute force and identifies specific weaknesses like common patterns, dictionary words, or insufficient length.
How to Use It
Type or paste a password into the input field. The strength meter updates in real time showing the score and rating. View the estimated crack time and read specific recommendations for making the password stronger.
Tips & Tricks
Longer passwords are almost always stronger than shorter complex ones. Avoid personal information like names, birthdays, or common words. Passphrases of four or more random words can be both strong and memorable.
Use Cases
Users check their existing passwords to identify weak ones that need changing. Security teams demonstrate password requirements during employee training. Developers test password validation rules in their applications.
