The idea which motivates this site is preventing weak passwords.

So…while I hope you do have super strong, site unique passwords, now there’s

a place where you can test that. What’s spooky is that the site seems to read your mind:

“The new project from Microsoft Research has a simple premise: you start typing one of your favorite passwords in its little text box, and it tries to guess what the next character is. And it's better at that than you might think.” – Gizmodo

So go here: https://telepathwords.research.microsoft.com/  and give it a shot.

How does it work?

Telepathwords tries to predict the next character of your passwords by using knowledge of:

• common passwords, such as those made public as a result of security breaches
• common phrases, such as those that appear frequently on web pages or in common search queries
• common password-selection behaviors, such as the use of sequences of adjacent keys

Anyway…it’s a good test, and when you get the check mark, you don’t have to go farther.
