Hey @Panicseller, here’s a detailed breakdown of what each backup file is and how they work Passport prime issues - #104 by Jack
As @qna mentioned, each Passport Prime Magic Backup (or manually downloaded backup file) will only contain information related to its internal apps. The Envoy Magic Backup (or manually downloaded backup file) will however have a view of everything in the app (without any seed material, of course), including all the Passport Core and Passport Primes paired, their names, account names, transaction tags and notes. It is intended to be a way to recover your Envoy form a fresh install to your last backed up state, so all this metadata is saved there. It is also true however that Envoy only sees Bitcoin wallet app’s information, and has no access or visibility to any of Passport Prime’s 2FA/Keys/Vault or any other app really, so only metadata of paired bitcoin accounts is saved in the Envoy Magic Backup (or the manually downlaoded backup).
