Two-factor authentication (also known as 2FA) is a method of confirming a user’s claimed identity by utilizing a combination of two different components. These components may be something that the user knows, something that the user possesses or something that is inseparable from the user. The classic example is a bank ATM card and the pin number the owner of the card knows. Two-factor authentication is also called Multi-factor authentication (Office 365 uses this term). More companies are offering this service to secure your account. AppleGoogle, YahooAmazonMicrosoft, InstagramLinkedin, GoDaddyDropbox, WordPress, Squareup and many other services call this service Two-Step Verification.   Twitter calls this Login Verification. Facebook calls this Login Approvals. Probably your bank has implemented Two-Factor authentication.

For a complete list of web sites and services offering Two-Factor Authorization go to Two Factor Auth (2FA).

Enabling Two-factor authentication makes your service way more secure than simply using a password. What are the odds that a hacker knows your password and has your mobile device?  2-Step Verification can help keep hackers out, even if they have your password! Google has made it very simple to implement and enable 2-Step Verification. Connectech recommends you use 2-Step Verification. Watch this short video that explains how to set up 2-Step Verification for Google services:
