WhatsApp is working on password-encrypted cloud backups
WhatsApp is an app whose messages, calls and video calls are end-to-end encrypted, so no one can see them. However, backups stored in the cloudnamely iCloud and Google Drive, they are not. They are not protected like messages. In fact, WhatsApp itself warns that:
“The content and messages that are backed up are not protected by WhatsApp’s end-to-end encryption while on Google Drive.” – Google Drive backup FAQs.
“Backed up content and messages are not protected by WhatsApp end-to-end encryption while in iCloud” – ICloud Backup FAQs.
Nevertheless, that seems to be close to changing, since WhatsApp is working on the encryption of said backup copies using a password, as collected in WaBetaInfo.
More secure cloud backups
As previously announced, @WhatsApp is working on cloud backups encryption.
The chat database and media will be safe from unauthorized access when using a password. The password is private and it’s not sent to WhatsApp.
It will be available in a future build for iOS and Android. pic.twitter.com/Lp06PaECBX

According to the well-known “filter” of WhatsApp functions, the most popular messaging application in our borders will allow you to encrypt your backups in the cloud. As we can see in the screenshots that accompany this tweet, WhatsApp will protect the backup copies with a private password that “is not sent to WhatsApp.”
When the backup is stored in the cloud, it will be protected by that password. What’s more, the application will ask the user for the password when they want to recover their chats, images and videos. Since WhatsApp does not store the password, it will not be possible to recover it in case of loss or forgetfulness.
From WaBetaInfo they remember that the database of the chats stored in the backup copy is encrypted, but that the algorithm is reversible and it is not end-to-end encrypted. In addition, WaBetaInfo ensures that local backups, which are stored in the memory of Android phones, will also be compatible with this new security measure.
For the moment there is no news about its official arrival on all smartphones, so it will be time to wait. On the other hand, it should be noted that this is not the first time we have heard about this function. Last May 20 WaBetaInfo advanced the arrival of encrypted backups, but so far they have not materialized officially.
