End-to-end encryption question
I have a quick question regarding end-to-end encryption. Facebook is looking to introduce E2EE as the default across all of its messaging platforms in the next year or so. My question is this:
Say I exchange messages with a friend over the new E2EE Facebook Messenger (or if we have historic messages that exist prior to the update to E2EE). We both then get new laptops, new smartphones, tablets, etc.
Will the new devices still be able to access our historic chat logs (that either pre-date E2EE or occurred afterwards), or will it be as if those chats never existed, as E2EE relies on the specific *device* to decrypt them, and thus aren’t stored?
