Your Passport is a secret recovery key for the encrypted watch index. The durable watches still run in the cloud; the Passport lets another browser recover their opaque references without an email profile.
Treat the Passport key like a password. Anyone holding it can restore the watch index. It does not reveal your passwords, browser history, or ChatGPT conversations.
