I recently set up a new Android device by migrating from an existing one using Google's migration setup (I don't think there was any device/manufacturer custom transfer going on). This was a wifi only transfer which supposedly was based on app data backup to Google drive.
When I went to set up 1Password on the new device I expected to have to enter/scan my account's secret key, but the app detected my saved account and all I had to enter was the master password. I've seen similar questions to this related to iCloud keychain on the mac but not to Android -- is the secret key stored in Google drive device backups or does this mean that there was actually some local network/bluetooth device->device data transfer going on? (The first possibility seems concerning but the second one much less so).
