How to Set Up Two-Factor Authentication

Leo has talked a lot on the Tech Guy show about using two factor authentication wherever possible to ensure the security of your online accounts. Two factor authentication requires more than just a 1 factor to login. This could include two of the following: something you are (such as biometrics like fingerprints or iris scans), something you know (a password), or something you have (a smartphone or hardware key). This could be called many things, including “Two-Step Verification” and “Two-Factor Authentication” depending on the site.

Episode 1375

John from Portland, ME
Windows Start Menu

John wants to know if he can reactivate Windows after replacing the Motherboard. Leo says he probably can. He'll just have to contact Microsoft and tell them what he's had to replace, and they will understand and authenticate. If he replaced more than half the computer, they may take issue. But with just replacing the motherboard, he should be able to get it authenticated. Windows may reject him when he tries, but then he can just contact Microsoft.

Leo says that financial transactions and other personal information will be pulled by credit reporting agencies to verify you are who you say you are. Larry is concerned because of errors on his credit report, and worse, it gets people used to having their personal data as public information.
