WhatsApp Will Finally Let Users Encrypt Their Chat Backups in the Cloud
WhatsApp said on Friday it will give its two billion users the option to encrypt their chat backups to the cloud, taking a significant step to put a lid on one of the tricky ways private communication between individuals on the app can be compromised. From a report: The Facebook-owned service has end-to-end encrypted chats between users for more than a decade. But users have had no option but to store their chat backup to their cloud -- iCloud on iPhones and Google Drive on Android -- in an unencrypted format. [...] Now WhatsApp says it is patching this weak link in the system. The company said it has devised a system to enable WhatsApp users on Android and iOS to lock their chat backups with encryption keys. WhatsApp says it will offer users two ways to encrypt their cloud backups, and the feature is optional. In the "coming weeks," users on WhatsApp will see an option to generate a 64-digit encryption key to lock their chat backups in the cloud. Users can store the encryption key offline or in a password manager of their choice, or they can create a password that backs up their encryption key in a cloud-based "backup key vault" that WhatsApp has developed.
