How to Set Up Two-Factor Authentication (2FA) on Your Holidu Account

To keep your account and data secure, Holidu uses Two-Factor Authentication (2FA) for all hosts that do not use social logins (where 2FA is also offered, for example by Gmail). This extra layer of security protects your account even if someone else knows your password. 2FA is mandatory for all hosts with published properties.

What is 2FA?

Two-Factor Authentication requires two things to log in:

1. First factor: Your email and password
2. Second factor: A one-time verification code, sent via one of the following methods:
   • SMS (recommended)
   • Authenticator app (e.g., Google Authenticator, Authy)
   • Email (no longer supported for new hosts)

You can set up multiple methods for backup access. However, you can only use one instance of each method—for example, only one phone number, one email address, and one authenticator app can be registered at a time.

Where to Set Up 2FA

1. Log in to your Holidu Host Account. You may be prompted to set up 2FA immediately after login. If not, continue to step 2.
2. Go to: Holidu Logo > Security
3. Click Configure next to the authentication method(s) you want to activate.

Choose Your 2FA Method

Method 1: SMS (Mobile Phone) — Recommended

SMS is the fastest and easiest method for Two-Factor Authentication. You'll receive a 6-digit code via text message each time you log in.

1. Select SMS from the list.

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

1. Enter the 6-digit code you receive and click Verify.

1. You'll see a confirmation message once the setup is complete. Congratulations, your account and your data are now secured!

Method 2: Email (No Longer Available for New Hosts)

Email authentication sends a verification code to your registered Holidu email address. Please note that this method is no longer available for newly registering hosts.

1. Choose Email authentication from the list of methods.

1. The system will send a verification code to your registered Holidu email address.
2. Check your inbox, enter the code, and click Submit code.

1. You'll see a confirmation message once the setup is complete. Congratulations, your account and your data are now secured!

Method 3: Authenticator App

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 that only you can see. Unlike text messages or emails, the app works even without internet or mobile signal, because the codes are created directly on your device.

1. Download an app like Google Authenticator (Android | Apple) or Authy (Android | Apple).
2. Select Authenticator App from the list.

1. Scan the QR code displayed on your screen (or use a manual code if scanning doesn't work).

1. Enter the 6-digit code generated by the app, give the device a name (e.g., "My mobile phone"), and click Submit.
2. You'll see a confirmation message once setup is complete. Congratulations, your account and your data are now secured!
3. Authenticator apps generate codes locally, so they work without internet or mobile signal.

After Setup

From now on, logging in requires:

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

You can manage your 2FA settings at any time via the Security section in your Holidu account.

Tips for Success

• We recommend starting with SMS, as it's the fastest and easiest method.
• Enable at least two different methods in case you lose access to one.
• Remember: Only one instance of each method can be used (one email, one phone, one authenticator app).
• Keep your phone or email address up to date to ensure you always receive verification codes.
• Save backup codes in a safe place if your authenticator app provides them.

Frequently Asked Questions (FAQ)

Why do I need to set up 2FA?

Two-Factor Authentication protects your account from unauthorized access, especially if your password is ever compromised. It's an essential security measure to safeguard your property listings, booking information, and financial data.

I do not see an option to set up 2FA in my account. Why?

Two-Factor Authentication is only available if you use a combination of email and password to log in. If you are using a login method like Facebook or Google, you are already secure, since they also offer Two-Factor Authentication through their own security systems.

What if I lose access to my phone or email?

You can use a backup method to log in. We recommend setting up a secondary verification method (for example, both SMS and an authenticator app) to avoid being locked out of your account. If you lose access to all methods, contact Holidu support immediately for account recovery assistance.

Can I skip setting up 2FA?

Only temporarily. Two-Factor Authentication becomes mandatory once you publish a property on Holidu. If you have not yet published a property, you may delay setup, but we strongly recommend enabling it as soon as possible.

How long does setup take?

Less than a minute in most cases. The process is quick and straightforward, regardless of which method you choose.

Can I use more than one method?

Yes! You can activate more than one method for backup purposes. For example, you could set up both SMS and an authenticator app. However, you can only have one instance of each method active at a time.

What if I don't receive the code?

If you're not receiving a code, try the following:

• For SMS: Check your signal strength and ensure your phone can receive text messages. Wait a few seconds as delivery can take time.
• For Email: Check your spam or junk folder, as the code email may have been filtered there. Whitelist the Holidu email address.
• For Authenticator App: Ensure the time on your device is synchronized correctly, as the app relies on accurate time to generate codes.

If you still don't receive a code, contact Holidu support for assistance.

Do collaborators need to activate 2FA too?

Yes, if they have access to published properties on your account, they should also set up Two-Factor Authentication to maintain security standards and protect your listings.

Can I change my 2FA method later?

Yes, you can change or remove 2FA methods at any time. Go to Security Settings in your account to update, add, or remove authentication methods as needed.

Is 2FA mandatory for all hosts?

Two-Factor Authentication is mandatory for all hosts with published properties. If you do not yet have published listings, setup is optional but highly recommended for account security.
