Definition: One of the keys in determining if the message or file you are receiving is safe is to first authenticate that the person who sent it is who they say they are. Authentication is the process of determining the true identity of someone. Basic authentication is simply using a password to verify that you are who you say you are. There are also more complicated and more precise methods such as biometrics (fingerprints, retina scans).
I have a passion for technology and gadgets--with a focus on Microsoft and security--and a desire to help others understand how technology can affect or improve their lives. I also love spending time with my wife, 7 kids, 2 dogs, 5 cats, 1 rabbit, 2 ferrets, a pot-bellied pig, and sulcata tortoise, and I like to think I enjoy reading and golf even though I never find time for either.
