Two-Factor Authentication (2FA) adds a second layer of security to your Holidu host account. After you enter your password, you confirm your identity with a one-time verification code. You can set up 2FA with SMS, email, or an authenticator app in just a few minutes, and it is mandatory once you publish a property.

What is Two-Factor Authentication (2FA)?

Two-Factor Authentication requires two things to log in to your Holidu host account:

1. First factor: your email address and password.
2. Second factor: a one-time verification code, sent through one of the following methods:
   • SMS to your mobile phone
   • Email
   • An authenticator app, such as Google Authenticator or Authy

You can set up more than one method for backup access. However, each method can be registered only once. For example, you can use one phone number and one authenticator app.

Holidu offers 2FA to all hosts who log in with an email and password. If you log in with Google or Facebook, your account is already protected by the two-factor authentication offered by those providers.

Where to Set Up 2FA on Your Holidu Account

1. Log in to your Holidu Host Account. You may be prompted to set up 2FA right after logging in. If you are not prompted, continue to step 2.
2. Open the Profile Picture Menu, then select Security.
3. Click Configure next to the authentication method you want to activate.

How to Set Up 2FA: Step-by-Step Guide for All 3 Methods

Choose the method that works best for you. Follow the steps for SMS, Email, or Authenticator App below.

Method 1: How to Set Up 2FA with SMS (Mobile Phone)

SMS is the fastest and easiest way to set up 2FA. Follow these steps:

1. Select SMS from the list of authentication methods.

1. Enter the phone number you want to use, then click Get SMS Code.

1. Enter the 6-digit code you receive by text message, then click Verify.

1. You will see a confirmation message when the setup is complete. Your account and your data are now secured.

Method 2: How to Set Up 2FA with Email

1. Select Email from the list of authentication methods.
2. Follow the on-screen instructions and confirm the email address you want to use.
3. Enter the 6-digit code sent to your email inbox, then click Verify.
4. You will see a confirmation message when the setup is complete. Your account and your data are now secured.

Tip: Check your spam or junk folder if the code does not appear within a few minutes.

Method 3: How to Set Up 2FA with an Authenticator App (Recommended)

An authenticator app is a small program you install on your smartphone or tablet. It generates a new 6-digit security code every 30 seconds, and only you can see it. Because the codes are created directly on your device, the app works even without an internet connection or mobile signal.

1. Download an authenticator app such as Google Authenticator (Android | Apple) or Authy (Android | Apple).
2. Select Authenticator App from the list of authentication methods.

1. Scan the QR code shown on your screen with your authenticator app. If scanning does not work, enter the manual code instead.

1. Enter the 6-digit code generated by the app, give your device a name (for example, "My mobile phone"), then click Submit.
2. You will see a confirmation message when the setup is complete. Your account and your data are now secured.

What Happens After You Set Up 2FA?

From now on, logging in to your Holidu account requires two steps:

1. Enter your password.
2. Enter the 6-digit code from your chosen 2FA method.

You can manage your 2FA settings at any time in the Security section of your Holidu account. You can add, update, or remove methods there.

Tips for Successful 2FA Setup

• Start with SMS if you want the fastest and easiest setup.
• Set up at least two different methods so you can still log in if you lose access to one of them.
• Remember that each method can be used only once. For example, you can register one phone number and one authenticator app.
• Keep your phone number and email address up to date in your account so you always receive your codes.
