The  How secure is mypassword   website works estimating a brute force attack.

How It Works

It's just a bit of simple maths:

(number of possible characters to the power of length of the password) divided by calculations per second

Thank you for sharing.

Since their release of this tool and before that the strength checker used for Hotmail / Live accounts has always felt lacking. With any long word, you get the strong grading. Google version is only slightly better.

The site' look very nice and explains it easily. My personal preference has always been They provide the source code that you can download and run manually. Why, you might ask? Just like Googles search bar, every keystroke you input could be recorded by the owner of the website, improving the attacks of the bad guys.

Unfortunately, they all seem to measure different criteria. This one only shows the time required, but that time is way different to

Bonus points for those noticing that all three sites use normal HTTP instead of HTTPS to encrypt your key strokes.

Please mark the post that best solves your problem as the answer to this thread.

It's not exactly that case. Google Search bar does transfer the data you type there, these tools do not. This means it is not important whether you use HTTP or HTTPS, your password is checked only within the process of your browser using Javascript. In my opinion this password checker is the best. Besides brute-force calculations it can check your password against dictionary words including some mutations and chaining. As we are talking about HTTP and HTTPS, this one also do not send your password to the server for brute-force analyzes, but does so when you want to use that dictionary check. Instead of HTTPS, an encryption is being used to hide your password from sniffing attackers. However, it is mentioned there that this is prone to MITM attacks and thus less secure than HTTPS. It would be better if it used HTTPS.
