📌 This article provides guidance for CX on how to assist users who are experiencing issues with identity validation at check-in.
Important Information
- This process is active only for Brazil and LATAM.
- Identity Validation at Check-in was designed to combat improper account sharing by adding an extra layer of validation for accounts flagged as suspicious.
- The identity validation format changes according to the Risk Level identified by the system:
- Low Risk: The user simply acknowledges the notification and changes the password if they wish.
- Medium Risk: The user can choose between validating via SMS or facial biometrics.
- High Risk: The user is required to complete facial recognition.
- The user can only perform a facial biometrics reset once. If the reset has already been done in Darwin, the button will be disabled and the case must be escalated to the Risk/Fraud Investigation - User group.

In this scenario, the user attempted to validate access by receiving a code via SMS but faced failures (e.g., did not receive the code or exceeded attempt limits). The guidance is to encourage trying validation using facial biometrics.
- Respond to the user asking them to try the process again using the facial verification option and close the ticket as Resolved.
⚡ Macro:
LATAM USER::Check-in & Bookings::Problems with SMS Validation
BR USER::Check-in & Bookings::Problemas com validação via SMS -
If the user actively requests a refund for the day(s) they were unable to check in due to this failure, follow the refund process to issue a partial refund for those specific days.
Remember: Refunds should only be processed if explicitly requested.
If the user reports camera permission issues during the facial recognition step (for example, a loop where the app requests camera access but phone settings do not enable this request), follow the instructions below:
- Ask the user to confirm if camera access permission is properly enabled and instruct them to clear the app data, using the macro below:
⚡ Macro:
LATAM USER::Check-in & Bookings::Camera Problem
BR USER::Check-in & Bookings::Problema com a câmera - If the user returns reporting the problem was not resolved, proceed to the steps detailed in the "Facial Scanning Issues" tab.
If the user has any issues with the facial validation itself (scan failure or photo not recognized), it may be necessary to reset the registered biometrics.
- If the ticket was opened by a Family Member (dependent), inform them that the account holder needs to contact us to proceed with the request.
⚡ Macro:
LATAM USER::Prevention::Family Member Account Management
BR USER::Prevention::Gerenciamento de Conta de Membro da Família - When the account holder contacts support, access the Darwin dashboard and locate the user's account.
-
Click on the "Fraud History" tab in the side menu and check if the "Reset facial verification" button is visible on the screen.
-
If the button is enabled: Click the button to delete the saved facial scan and fill out the pop-up details. After that, inform the user that an exclusive exception has been granted so they can try to re-register their face.
- Include the Zendesk ticket URL.
-
Describe the reason for the reset provided by the user (minimum 50 characters). Example: "User unable to check in due to facial recognition failure. Facial verification reset granted as an exception to allow re-registration.".
⚡ Macro:
LATAM USER::Check-in & Bookings:: Re-register facial authentication
BR USER::Check-in & Bookings::Recadastrar facial
- If the user actively requests a refund for the days they were unable to check in, process a partial refund proportional to those days.
Remember: Refunds should only be processed if explicitly requested. - If the biometrics problem persists even after the reset, apply the following macro requesting the device model, app version, and error screenshot.
Important: Only proceed with escalation if the user provides this information back.
