Various embodiments relate generally to electrical and electronic hardware, computer software and systems, wired and wireless network communications, and wearable computing devices for establishing a secure, closed-loop communication channel for authorizing access to rental properties. More specifically, a system, a device and a method are configured to facilitate authorization via secure communications between an inquiring entity and a responding entity to access a rental property. In one or more embodiments, a method can include establishing a data arrangement representing a messaging dialogue between an inquirer and a responder. The messaging dialogue may include data representing exchange of electronic messages. Further, the method may include suppressing transmission of the identity data of the inquirer and the responder during the exchange of the electronic messages to form secured messages, and generating anonymized transaction data representing authorization to access the rental property.
