Meta is finally replaces passwords with passkeys on Facebook

Facebook is introducing a new way to sign in that promises both simplicity and heightened security. The platform has begun rolling out support for passkeys on mobile devices, giving users a password-free method to log into their accounts. Designed to replace traditional credentials, passkeys use biometric authentication or a device PIN, offering a safer and more convenient alternative.

The feature will soon be available across both iOS and Android devices for Facebook users. Meta also plans to extend passkey functionality to Messenger in the coming months, allowing users to access both platforms using a single, unified passkey. Once enabled, the same passkey created for Facebook will automatically function for Messenger, streamlining the login experience.

But what exactly are passkeys? They are digital credentials that eliminate the need for passwords altogether. Instead of typing in a string of characters, users can authenticate themselves using the fingerprint, facial recognition, or PIN already configured on their device. Developed in collaboration with the FIDO Alliance—a global industry consortium focused on enhancing online authentication—passkeys aim to reduce dependence on vulnerable and outdated password systems. Meta is a member of the alliance and has adopted its standards to bolster account security.

Security remains a key focus. Passkeys are significantly harder to hack than passwords or even SMS-based two-factor authentication. Unlike traditional credentials, they can’t be phished or stolen via malicious websites. The biometric data or PIN used to generate the passkey never leaves the user’s device, meaning Meta cannot see, store, or share this sensitive information. This local storage model ensures that authentication remains both private and secure.

Beyond login functionality, Meta is looking to expand the use of passkeys to additional features. For instance, users will eventually be able to use their passkey to autofill payment details through Meta Pay or to protect backups of encrypted messages in Messenger. This indicates that Meta sees passkeys not just as a login method, but as a foundational element of its broader security infrastructure.

Setting up a passkey is designed to be quick and straightforward. Users can manage their passkey through the Accounts Center, found in the Facebook settings menu. They may also be prompted to set one up during a login session. After activation, the passkey will serve as a primary authentication method on compatible mobile devices, although passwords will still be supported for users accessing Facebook from older or non-compatible systems.

Meta’s move toward passkeys reflects a growing industry trend of moving away from passwords, which have long been seen as a weak link in cybersecurity. By embracing this technology, Facebook aims to deliver a more seamless and secure user experience—one that reduces friction while offering robust protection against online threats. As the rollout continues, users can expect an easier, safer way to access their accounts and interact across Meta's suite of services.
