What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a security mechanism designed to add an extra layer of protection when logging in to online accounts, systems and applications.

Hosted.com implemented two-factor authentication to ensure the highest level of security for our domain and website management, because 2FA serves as a safeguard against unauthorized access and helps mitigate the risks associated with various cyber threats.

Do I Need Two-Factor Authentication?

Traditionally, online accounts are secured using a single method of authentication, typically a password. However, passwords alone can be vulnerable to various online attacks such as phishing, or password leaks. Two-Factor Authentication enhances security by requiring users to provide two different forms of identification before gaining access to their accounts.

How does Two-Factor Authentication (2FA) Work?

When you log in to an online platform, instead of only entering your username and password, you are asked for one more level of security – this is usually referred to as two-factor authentication (2FA).

2FA is a a unique verification code that is displayed in the Google Authenticator app on your smartphone or other trusted device. Just enter that code and your secure login will be completed.

What are the Best 2FA Apps?

The most commonly known two-factor authentication apps are:

• Google Authenticator – for Android & iPhone
• Microsoft Authenticator – for Microsoft products
• Authy – for Apple watch users

How to Use Two-Factor Authentication (2FA)

When logging into your Hosted.com account, you can set up a 2FA which requires that you not only have to enter your username and password, but you also need to enter a randomly generated 6-digit code that is sent to either your email address, or your cellphone.

This means that even if a 3rd party does manage to get access to your Hosted.com account log in details, they will still be unable to access it, as they would not be able to provide the random 6-digit code required as the final security check.

How to Setup 2FA

A 2FA can be set up by using an app such as Google Authenticator, or Microsoft’s Authenticator App. Once you have set it up and enabled it, you can choose to receive the 6-digit code via text message, email, or through the app of your choice. This adds more convenience as you can choose the method that works best for you.

Levels of Authentication

• The first factor is typically your domain provider or hosting account credentials, including your username and password combination used to log into an account.
• The second factor introduces the next layer of authentication beyond the password which can be a one-time code sent to the user’s mobile phone, which they must enter to complete the login.
• Most Two Factor Authentication apps generate time-sensitive codes i.e., they need to be entered within a specific time frame before becoming obsolete.
• Some apps also offer biometric authentication allowing users to use fingerprint scans, facial recognition, or other biometric data as the second factor.
• Implementing Two Factor Authentication (2FA) helps protect crucial domain management interfaces as it adds a significant layer of resilience against unauthorized access, data breaches, and potential domain hijacking.

How to turn on Two Factor Authentication

As a web user, you will find that most online accounts nowadays, have an option to set up two factor authentication for logging in. This allows you to use one 2FA app for a number of different account logins, so that they are all in one place.

You may also have multiple 2FA apps over different devices if you so choose, simply logon to Google Play Store and download the Google Authenticator app (Android & iPhone) to your device and set it up. Similarly, you can do the same with Microsoft Authenticator and Authy for your Apple watch.
