urm, are you really sure about 2.?
i switched SIMcards recently (the number was migrated to the new card though) and flashed another ROM on my phone. It helpfully offered me to restore all messages and media from the server. (6+ months of history)
Sure it could use the IMEI for the encryption. But i'm unsure if it can access that datapoint from application context?
/edit: i just scrolled back to the first message i've got on my most messaged contact. its from 2014. i've switched devices and sim cards since then. The phone number is the only thing that stayed the same.
- Cyph0n 10y agoWhatsApp has an optional auto-backup feature that periodically backs up your messages to Google Drive (iCloud on iOS?). You can find it under Settings > Chats > Chat backup. It is an extremely smart way to allow users to backup their messages if needed, while also ensuring that WhatsApp doesn't have access to the backups. Once you activate a new phone, it will ask if you want to restore your messages from the latest backup. I guess it's using your Play Store account credentials to tie your SIM cards and phones together.
