The pre check-in URL provided by AirHost is safe to use for the following reasons:
1. Protection through Encrypted Communication
The URL and all entered information are encrypted using HTTPS (TLS 1.2/1.3), which prevents any third party from intercepting the communication.
Public-key cryptography is used, and each session is encrypted with a temporary key generated for that session, ensuring that plaintext data cannot be leaked.
2. Multiple Authentication Details Required
To access the pre check-in URL, all of the following three values must be correctly provided:
checkinCode
pinCode
UID
If even one of these values is missing, access to the reservation information is not possible.
These authentication details are generated using complex random strings, making guessing or brute-force attacks practically impossible.
These mechanisms ensure that guests’ personal information is securely protected, allowing them to use the service with confidence.
