Over the last few weeks there have been quite a few sites and newsletters that have linked to a new tool on the Microsoft site called Password Checker:
Do you use strong passwords?
A strong password should appear to be a random string of characters to an attacker. It should be 14 characters or longer, (eight characters or longer at a minimum). It should include a combination of uppercase and lowercase letters, numbers, and symbols.
Test the strength of your passwords: Enter a password in the text box to have Password Checker help determine its strength as you type.
It is a simple utility that does NOT send any information back to Microsoft. Everything is checked locally. I tested several of my passwords, and they all came back Strong, but not Best. They aren’t long enough I guess.
