What is 2FA?

Two-factor authentication is a second layer of security for your application and online access.  Take advantage of this option and set it up where ever it is offered.

Something You Know: your password is the most common first layer, but as we know, passwords are easy to steal, hack and sometimes we just give them away by sharing and by creating lousy passwords like 123456.  But a strong password is an important line of defense that you must embrace – learn more about building strong passwords here.

Something You Have: a common second layer comes from a text message or email sent with a code to enter to complete your access, or a code from an application on your device.  You have to get this code from a device that someone trying to log in as you would most likely not have in their possession – or also not have the password to open the device.  SIDE NOTE – always use a passcode/login on your devices and consider the implications of giving the code to your child to access your phone.  More sites are offering this as an extra layer of authentication that is worth the few additional seconds to log in.

Something You Are: you can also have this as a second or third layer (Multi-Factor Authentication), which would include bio-metrics, like a fingerprint.  Unlike using your fingerprint to unlock your phone, this would be used in combination with at least a password or access code for 2FA or both for Multi-Factor Authentication.

As for apps, the most popular ones include


Google Authenticator

Microsoft Authenticator

If your application or website supports use of authentication apps, they provide a QR code to scan for quick and easy set up.
