WhatsApp rolls out passkey encryption for chat backups, here’s how it works

WhatsApp is introducing passkey-encrypted backups for iOS and Android users, allowing them to secure their chat history using fingerprints, facial recognition, or device screen locks instead of passwords. The feature eliminates the need to memorize cumbersome 64-digit encryption keys, making backup protection more accessible through a simple tap or glance.
