I've been wondering about this for a while.
Now both whatsapp and Facebook have this, but surely they have the encryption keys too, or how else would they seamlessly fetch your messages and decrypt them when you get a new phone?
If they do, then what's the point?
- danielschonfeld 10y agoI don't know about either anything factual, but I believe it was said that WhatsApp crux in the e2e is the iCloud backup. I believe that's where your old message get restored from. I believe you can also disable that iCloud backup and thus the ability to retrieve those messages with a new phone. End-to-End means encrypted in transport and not saved (in any form that is decryptable) on their servers. To that, I believe whatsapp fulfills their end of the bargain.

- azernik 10y agoWhatsApp for Android doesn't seamlessly fetch and decrypt messages on new installations; you have to set up Google Drive backups from your old phone, and then set up restore from those backups on your new phone.
