🚧 This is new documentation for Codebook 4, it is still under development.
In order to use Codebook's Sync feature, you will need a Sync Key. This is a random key generated separately from your Master Password, used to encrypt all of your data when syncing with cloud services or over WiFi. You only need one Sync Key, which you then add to other copies of Codebook.
When no Sync Key is present, Codebook will prompt you to Setup Your Sync Key. Specifically, it asks, "Have you already created your Sync Key in another copy of Codebook?" If you have not, select No, and Codebook will create a one and store it in your encrypted database. You're all set!*
