We require you to have an Airbnb password, and to login to Airbnb with that Airbnb password.
If you are currently using Google, or Facebook, or any other social authentication method to connect to your Airbnb account, this authentication method is not compatible with our product at this point in time.
It's easy to create your Airbnb password:
Type in your email address
Follow the instructions from the email that you will receive
Reset your password (we recommend that you use a different one for Airbnb and Smartbnb, as is the best security practice).
Once this is completed, you can connect your Airbnb account again:
Go to Settings
Click on Connected accounts
Click on "Connect with Airbnb"
