When you are asked to upload a photo of your passport or ID card, the website handling that data must be transparent, secure, and established. This site currently fails on almost every metric that matters for a hospitality portal. It provides no clear ownership information, no contact details for the staff, and no privacy policy to explain how your sensitive personal data is stored or deleted. A legitimate hotel check-in system should always be reachable over a secure, encrypted connection, yet this one is currently offline and unable to handle data safely.
Because of these issues, you should be very careful. If you are staying at a property linked to hgwhite.it, contact the front desk directly through a phone number or email you found on a confirmed booking platform. Do not upload your documents to this site while it is in such a neglected state. There is simply not enough information here to tell if hgwhite.it is a scam, but the complete lack of basic operational standards makes it a poor choice for handling your private identity records.
