Use Authy for 2-Factor Authentication

Since many sites now allow (or even require) 2-factor authentication, it's a good idea to use an authentication app on your smartphone to get the security code. This is a much more secure method, because codes texted over SMS could be intercepted. There's also the danger of SIM cards being duplicated or even hijacked with some creative social engineering. The Authy app for iOS or Android is a good option, because it sends a secret number and combines it with the time of day so the code changes after 30 seconds.

Is my banking information safe?

Google Chrome

Episode 1384

Mike from Granada Hills, CA

Mike is worried that Google has all of his banking information. Leo says it's not to worry about. They don't have it. If anything, his browser has that information and that's much more dangerous. It may be a good idea to reset his browser to get rid of all that. Then turn on second factor authentication to make sure that any attempt to change his password or access his account will be stopped. Mike shouldn't worry about Google, though. They're quite secure, and Chrome is a secure browser.

What's to stop the Turkish iCloud hackers from getting my new password?

Apple iCloud

Episode 1374

Mike from San Diego, CA

Mike is worried about the Turkish Crime Family's iCloud hack. If he changes his password, couldn't they just hack it again to get them? Leo says that Apple has said it hasn't been hacked, and even if it had been, the hackers would have to "rehack" the system to get them. If Mike has turned on two factor authentication, they can't use his password anyway.

It's annoying to use two-factor, but it's the best last line of defense to prevent his account from being compromised. Also, he can use his TouchID on a new MacBook Pro and his iOS devices to insure verification.

Cheryl from Alexandria, VA

She can't get infected on that. Apple's iOS is very secure. But it's always a good idea to train herself not to click on links.

Episode 1211

Alan from Washington DC

Alan just installed Windows 10 on a few computers and wants to know if there's any reason to install a third party antivirus program with it.

Is there an alternative to 2nd factor authentication?

Episode 1206

Ben from Omaha, NE

Ben wants to know if we can ever move beyond second factor authentication. Can we move on to fingerprint reading? Leo says that is also second factor authentication. It's not just something you have, it's also something you are.

Windows Hello is a new type of two factor authentication, which uses a special depth sensing webcam for facial recognition and will log you in based on your face. But we can surely get rid of passwords, it's really a terrible system.

How often should I change my passwords?

Password

Episode 1154

Mike from Glendale, CA

Mike wants to know about passwords and how often he should change the ones on his computer. Leo says that local passwords, like for logging into his laptop aren't that big of a deal. Someone would have to have physical access to the computer and a lot of time to crack it. So that's not really the one to worry about. It's the passwords online, and even then, those passwords are encrypted. Those who change passwords a lot are those who have passwords that are shamefully easy to guess.
