The “second factor” comes in after you enter your username and password, which are considered to be the “first factor.” 2FA can be used to confirm your identity by asking for an extra piece of information. The additional information can be:

  • Something you know, like an additional passcode.
  • Something you have, like your phone to receive a one time authorization code.
  • Something you are, like a fingerprint or voice print. This is also called biometric security.

The idea is to provide another piece of information a hacker would not have, making it harder for the bad guy to break into your account.

The following is not an exhaustive list of services with 2FA ability, but we cover the major services everyone tends to use, and walk you through how to access. We will cover Amazon, Apple, Facebook, Google, Instagram, LinkedIn, Microsoft, and Twitter. Activate 2FA on all of these and you will be more secure. Once you have found their 2FA screens you can can set it up for each app.


First, launch on the desktop and login in to your account. Next, click the Menu icon in upper left-hand corner. Now, scroll down the drop-down menu to Your Account option.

Next, click on the Login & Security big button. Now, on the next page, click Edit next to Two-Step Verification (2SV) Settings. The preferred method is an authentication app (scan the QR code); phone number(s) are the backup method. Refer to below image where I already have 2SV based on my phone number (which is dimmed out):

If you think your account has been comprised, go back to Login & Security and click the Edit button next to Secure Your Account.


Following are the steps on how to access 2FA for Apple using either iOS or macOS.

On iOS go to:

Settings > [your name at the top] > Password & Security > Turn on Two-Factor Authentication.

System Preferences > iCloud, then sign in, click Account Details > Security > Turn on Two-Factor Authentication.

Note! once Apple 2FA is activated for two weeks, you can not turn it off. “Certain features in the latest versions of iOS and macOS require this extra level of security, which is designed to protect your information,” according to Apple. See below image for iOS:

When you enter a password to access your Google account for almost any service, if 2SV is on, there are multiple options to get that second step. First among them now: the Google Prompt.
