solution for automatically generating door code on Schlage lock

[Leon Lee]

Hi, Fellow STR investors

Currently, I am using a third-party PM software to automatically generate a door code that is the last 4 digits of guest's registered phone number and then manually set the same code on my Schlage smart lock app for guests (with the same expiration date as the guest's checkout date). As the portfolio grows, this annual setting will no longer work and error prone. What is the best third party app that can be connected to Guesty that will automatically generate a unique door code to each guest depending their booking date?

Thanks in advance!
