2 factor authentication

How does 2 factor work if you're using Find My iPhone?

Episode 1434

Tom from Florida
Find My iPhone

Tom wants to know how Apple's 2 Factor Authentication works with Find My Phone. When he logs into iCloud to look for his phone, it'll send his 2 Factor Authenticator to his phone. But how can he find his phone that way? Leo says that Apple does 2 Factor different from everyone else. If he has another Apple device like an iMac or iPad, then he could do it. It'll send the code to all of his Apple devices. Not just the iPhone. He can also use trusted phone numbers and enroll a landline or his wife's phone that they will call and give him the number audibly.

Why doesn't two factor authentication work on my Gmail anymore?

Saren from Los Angeles, CA
Google Authenticator

Saren hasn't been receiving the two factor authentication code he normally gets for his Gmail account. He would normally get it through his Google Voice number. Leo says it's insecure to send those two factor codes through SMS, because someone could spoof his number and get the text message. Google may have even stopped supporting SMS in favor of its Google Authenticator app.

What can I do if my Google account has been hacked?

Episode 1412

Carla from Orange County, CA
Gmail

Carla's Google account has been hacked. She sees things in her Gmail account she doesn't recognize and her YouTube watch list has things on it she never watched. Leo says Google has a security checkup that she can use to see if she's being hacked and she can disconnect any device she doesn't recognize. Carla should also engage 2 Factor Authentication. Obviously, Carla is going to want to change her password as well.

Prevent Your Accounts From Being Hacked

Securing your online accounts is vitally important. The consequences of being hacked can be great — someone could lock you out of your email account. If that account is used for password recovery for your other accounts, then a hacker could get access to all of those as well. There are a few basic things that you should make sure you do to protect your email account:

1. Provide a secondary email address for recovery.
2. Provide a phone number for password recovery.
3. Turn on 2 Factor Authentication.

How can I get my gmail account back from a hacker?

Episode 1408

Clinton from Alberta, Canada
Code

Clinton's Google account was hacked, and the password recovery was changed to another email address. Leo says that's why Google and Leo recommends 2 Factor Authentication so that he would be contacted should a password change happen. He can also use a secondary email. Clinton can contact Google and they can perhaps get his account back by answering questions that only he would know about.

He should keep in mind that if he used this as a recovery email for other sites, they are vulnerable as well. So he'll have to get it back ASAP before more damage is done.

Log into Facebook with a One-Time Password

Using Facebook on a public computer, or even on a friend's computer, can be risky. Facebook stores a cookie in the browser that enables the user to get into the site without actually logging in. This would make it possible for someone else to easily gain access to your account. Instead of avoiding Facebook entirely, there is a way you can still use it and prevent someone else from being able to get in — by using a one-time password.

Why can't I access my email?

Buzz from Huntington Beach, CA

Episode 1399

Buzz is having a problem with 2 factor authentication on Apple's Mail app. He is able to input his password, but it won't take it. Leo says that Apple should create an authenticator program that can be used to verify user identity that can then be texted to him. That way, he's protected. If he's having trouble with it, Apple is really the only one that can solve the issue. It may be that his password has been changed and he forgot.
