WhatsApp deploys end-to-end encrypted chat backups on iOS and Android to prevent anyone from accessing your chats, regardless of where they are stored.
Currently, WhatsApp allows you to create backups of all your chats and store them on online storage services. For iOS users, your backups are stored on iCloud and for Android, they are stored on Google Drive.

WhatsApp gets end-to-end encrypted chat backups
Starting today, Facebook announced that WhatsApp is rolling out a new feature that allows you to perform end-to-end encryption of your chat backups, regardless of where they are stored.
While this feature is not yet rolled out to everyone, users will be able to assign a password that only they know to encrypt backups before they are uploaded to iCloud or Google Drive.
“You can now secure your end-to-end encrypted backup with a password of your choice or a 64-digit encryption key that only you know,” Facebook announced today.
“Neither WhatsApp nor your backup service provider will be able to read your backups or access the key required to unlock them. “
Users should also use this same password to restore all backups in the future, preventing them from being accessed by anyone else.
Facebook says they’re slowly rolling out this feature for those running the latest version of WhatsApp, so it may take a while before it reaches everyone.

- Open WhatsApp.

- Faucet To continue, then follow the prompts and enter a password or key when prompted.
- Faucet Ended, and wait for WhatsApp to prepare your end-to-end encrypted backup. While creating an encrypted backup, the app may prompt you to connect your device to power.
Once end-to-end encrypted backups are enabled, you will not be able to restore backups to your device without knowing the password.
You can always deactivate this feature by going back to the End-to-end encrypted backup setting and turn it off.
