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). This extra layer of security protects your account even if someone else knows your password. 2FA will be mandatory for all hosts with published properties, but it can be set up early to avoid login issues.

What is Two-Factor Authentication (2FA)?

Two-Factor Authentication requires two things to log in:

1. Your password
2. A one-time verification code, sent via one of the following methods:
   1. SMS (recommended)
   2. Email
   3. Authenticator app (for example, Google Authenticator or Authy)

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 2FA method. A verification code is sent directly to your phone via text message.

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

Method 2: Email

Email authentication sends a verification code to your registered Holidu email address. This method is useful as a backup option.

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 will 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 does not work).
2. Enter the 6-digit code generated by the app, give the device a name (for example, "My mobile phone"), and click Submit.
3. You will see a confirmation message once setup is complete. Congratulations, your account and your data are now secured!
4. 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 is 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).
• Store backup codes in a safe place if your authentication provider offers them.
• Update your backup phone number or email if they change.

Frequently Asked Questions (FAQ)

Why do I need to set up 2FA?

To protect your account from unauthorized access, especially if your password is ever compromised. 2FA is mandatory for all hosts with published properties on Holidu.

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

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

What if I lose access to my phone or email?

You can use a backup method or contact Holidu support to recover access. We recommend setting up a secondary verification method to avoid any incidents.

Can I skip setting up 2FA?

Only temporarily. It becomes mandatory once you publish a property.

How long does setup take?

Less than a minute in most cases.

Can I use more than one method?

Yes! You can activate more than one method for backup. This ensures you always have access to your account.

What if I do not receive the code?

Check spam folders (email), signal strength (SMS), or time sync on your device (authenticator app). Still no luck? Contact Holidu support to get help.

Do collaborators need to activate 2FA too?

Yes, if they have access to published properties.

Can I change my 2FA method later?

Yes, go to Settings > Security to update or remove methods at any time.
