WhatsApp is expanding its security features and introducing passkeys for backups as well. This takes the messenger service another step towards a password-free future. Previously, passkeys could only be used for direct account access, while backups required a separate password. With the new update, this changes: backups will now also be protected by passkeys. This provides greater security and reduces the effort required for data recovery.

WhatsApp is one of the world's most important communication platforms. Countless messages, photos, videos, and voice notes are sent via the app every day. Many users also utilize the backup function to save chats and media. These backups, like the chats themselves, are protected by end-to-end encryption, but accessing them previously required an additional password. This was not only cumbersome but also vulnerable to security issues – for example, if passwords were forgotten or stolen in phishing attacks.

With its new passkey support for backups, WhatsApp solves precisely this problem. The update brings a simpler and more secure system that noticeably improves the handling of backups.

Passkeys: How they work and why they are more secure

Passkeys replace traditional passwords with digital keys stored on a device. Access is usually granted via biometric features such as fingerprint or facial recognition, or alternatively via a PIN or a secure device. This eliminates the need to enter or remember a password, significantly reducing the risk of data leaks and phishing.

Unlike traditional login methods, passkeys are never sent to servers but are managed locally. This makes them one of the most secure forms of authentication currently available. WhatsApp is thus using a technology also employed by companies like Google, Apple, and Microsoft.

What changes with the WhatsApp update

Previously, anyone who saved WhatsApp backups to Google Drive or iCloud had to set a separate password. With the new feature, this step is no longer necessary. In the future, the passkey will protect not only access to the account, but also the entire backup – including chats, photos, videos, and voice notes.

According to Engadget, the rollout of passkeys for backups starts immediately. However, it may take several weeks before the feature is available to all users. After updating, the new option can be activated in WhatsApp settings. This can be found under Settings → Account → Passkeys.

The update not only simplifies backup management but also enhances overall system security. Because passkeys are stored locally, they cannot be intercepted via phishing emails or data leaks. Furthermore, the risk of losing access to backups due to a forgotten password is eliminated.

Why WhatsApp relies on passkeys

The move towards passkeys is part of a larger development in the tech world. More and more services are abandoning traditional passwords because they are considered insecure and impractical. Passkeys, on the other hand, are seen as a modern standard that combines security and user-friendliness.

WhatsApp began integrating passkeys as a login method last year. Extending this to backups was therefore a logical next step. This creates a unified security architecture where chats, logins, and backups enjoy the same level of protection.

For those who have been using WhatsApp for a long time, this means one thing above all: more security with less effort. No additional password, no guesswork when codes are forgotten, no vulnerability to phishing.

WhatsApp focuses on both convenience and security.

With the introduction of passkeys for backups, WhatsApp is taking a sensible and long overdue step. The new feature complements the existing end-to-end encryption and ensures a fully protected data flow – from the message through the backup to the restore.

The rollout begins immediately, although it may take some time for all devices to receive the update. After activation, accessing backups will only require biometric login or a registered device.

Passkeys are not only more secure, but also more convenient. WhatsApp is thus creating a clear foundation for the future: communication without passwords – simple, fast, and secure. (Image: Shutterstock / BongkarnGraphic)
