What is an Authenticator App?

Authenticator apps provide extra security to online accounts, including your emails.

By creating multiple steps to log into your accounts, you will reduce the risk of being hacked, and having personal information leaked.

Depending on the type of authentication, either two-factor authentication or multi-factor authentication, you will follow different steps to improve the security of your account.

Authentication apps send you a one-time-only code only you will receive to log into your account.

How to use an authenticator app

Once you have followed the verification steps, you will need to sign into your accounts by first using your password, and then the code your authenticator app sends.

You may have to set up different types of authentications. This can be either of the following three things:

  1. Something you know – your password.
  2. Something you have – a physical authentication object.
  3. Something you are – your face or fingerprint.

What is the Difference Between 2FA and MFA?

The difference between the 2FA and MFA is very simple.

2FA = Two-Factor Authentication

Two-factor authentication means two ways of signing into your account.

This is usually by something you know (your password) and something you have (your smartphone which a code can be sent to).

Most of the time, you will be sent an SMS containing a code. However, it has recently been discovered hackers can easily reroute text messages meaning your account can become compromised.

Most apps give you the option of how you want to receive the code.

With an MFA you can use:

MFA apps are known to be more secure since you are creating multiple pathways to access your accounts, making it harder for your accounts to be compromised.

However, 2FA apps also provide a lot of security when not using SMS.
