How to Lock WhatsApp Chat History With Fingerprint or Face ID

WhatsApp has introduced a new passkey encryption feature for chat backups, which allows users to protect their messages without relying on passwords or long encryption keys. This Thursday, the update has been rolled out and it uses device-level security methods like fingerprint, facial recognition, or screen lock to keep the chat data protected.

Previously, for backup protection, WhatsApp users had to create and manage separate passwords or 64-digit encryption keys for Google Drive or iCloud storage. The new approach integrates backup encryption with the device's security, thereby making it easier. A simple tap or glance is now enough to lock and later unlock chat backups, thus ensuring privacy even in cases of the phone being lost or replaced.

Activating Passkey Encryption The passkey encryption feature will take some time to reach all users. By going to the app Settings > Chats > Chat Backup > End-to-End Encrypted Backup, the user can turn on passkey protection. After turning it on, the entire chat history, including images and audio messages, can be protected without any manual encryption key handling.

WhatsApp end-to-end encryption already in place makes it so that not even the service provider can have access to messages and calls as only the sender and the receiver can read them. Each communication is encrypted automatically with a unique digital key that only the two involved have but WhatsApp has no access to it. The application of backup passkey encryption by the platform does mean that the same level of protection is granted to the stored chat data now and is even less of a hassle for the user.

All the messages sent to business accounts are first encrypted and then delivered through the Signal protocol. The businesses, however, are allowed to manage the messages according to their privacy policies. This might sometimes be the case when neither employees nor third-party suppliers would access the content, yet, the chat data could still be used for marketing or campaigning through the Meta platforms.

By implementing device-linked passkeys instead of traditional passwords, WhatsApp eliminates all the difficulties in securing chat backups. As a result, users are able to safeguard the whole lots of conversations, multimedia, and voice notes easily, thus guaranteeing privacy without having to deal with the complicated encryption process.
