WhatsApp has introduced a new passkey-based authentication system for encrypted backups, giving users the ability to restore their chats using fingerprint, Face ID, or their screen lock code.

The update marks a major shift from the platform’s previous method, which relied on manually created passwords or 64-character encryption keys. According to Meta, the change will make restoring chat histories safer and more convenient.

“With passkeys, users no longer need to remember complex passwords or store long encryption keys. Access to encrypted backups can now be verified directly through the user’s device,” the company said.

Simplifying Secure Backup Access

Previously, WhatsApp’s encrypted backups, introduced in 2021, required users to set a password or save a long encryption key. While the system enhanced data security, it also carried a major drawback: users risked permanent data loss if they forgot their password or lost the key.

The new passkey system eliminates this risk by tying authentication directly to a user’s device. Whether users unlock with biometrics or screen lock codes, restoring backups will now be faster, simpler, and more secure.

Gradual Global Rollout Begins

WhatsApp, which surpassed 3 billion active users in May, announced that the new feature will roll out gradually over the coming weeks and months.

“This feature will be rolled out to users in the coming weeks and months, so you might have to keep an eye on when it becomes available to you,” WhatsApp stated.

Users can check if the feature is active by navigating to:
Settings > Chats > Chat backup > End-to-end encrypted backup, and looking for the ‘Use passkeys’ option.

Early tests by Nairametrics confirm that the feature is already available in Nigeria, with some users able to activate and use passkeys through their WhatsApp settings.

Part of Meta’s Broader Privacy Push

The introduction of passkeys aligns with Meta’s ongoing efforts to enhance privacy and fight online scams across its platforms.

In August, WhatsApp launched several safety tools designed to protect users from fraud in both individual and group chats. The company reported banning over 6.8 million accounts linked to scam centres operating in multiple countries.

Additionally, WhatsApp rolled out new safety overviews that notify users when they are added to unfamiliar groups and provide warnings before they interact with people outside their contact list.

Meta Partners with OpenAI to Combat Scam Messages

Meta also revealed that WhatsApp is working with OpenAI to identify and block fraudulent activity linked to AI-generated scam messages. The collaboration recently helped disrupt fraud operations traced to Cambodia, according to the company.

These initiatives, Meta said, are part of its broader goal to strengthen user security, combat scams, and refine encryption features for its global user base.
