Password Strength Checker
Check how strong your password is
About the Password Strength Checker
The Password Strength Checker rates how strong a password is and shows which basic requirements it meets: length, mixed case, numbers and symbols.
How it works
The checker gives one point each for reaching 8, 12 and 16 characters, and one point each for mixing upper and lower case, including digits and including symbols. The total maps to a rating from Very Weak to Very Strong. Checking happens entirely in your browser as you type.

Frequently Asked Questions
Q. Is my password sent anywhere?
No. It is checked locally in your browser and never transmitted or stored. Even so, avoid typing passwords you actively use into any website.
Q. Does a strong rating mean my password is safe?
Not always. Common phrases and reused passwords can be guessed even if they look complex. Use a unique password for every site.
Q. What makes a password strong?
Length above all. A random 16-character password is much stronger than a short one with symbols. Our Password Generator creates these for you.
