This update allows users to protect their backups with biometric authentication, such as fingerprints or facial recognition, eliminating the need for complex passwords or lengthy keys. As a result, users can secure their messages, photos, and voice notes more conveniently. This upgrade aims to simplify the protection of valuable personal information stored in backups.
