Facebook is introducing passkeys as a new login option for Android and iOS users, moving towards password-free authentication. This feature allows users to sign in using their fingerprint, face ID, or PIN, with biometric data securely stored on the device and never shared with Facebook, as per Meta.
For the unversed, passkeys are a modern, phishing-resistant login method developed by the FIDO Alliance. Unlike traditional passwords, they rely on cryptographic keys unique to each account, offering strong protection against hacking tactics like brute-force attacks and credential theft.
Initially limited to the Facebook app, the feature will soon expand to Messenger and other services. Meta says passkeys will also support encrypted chat access and payment autofill via Meta Pay in future updates.
How to enable passkey login?
To set up a passkey, you can navigate to the ‘Accounts Centre’ in the Facebook app settings or follow the on-screen prompt during login. The system assigns a passkey name based on the user’s verified email address or, if unavailable, their phone number—this name is fixed and can’t be changed, even if contact details are updated later.
Beyond login, passkeys will soon unlock more features. Meta confirms upcoming support for using passkeys to access encrypted Messenger backups and autofill payment details via Meta Pay. These additions reflect Meta’s broader push to adopt modern security standards while making account access and management more seamless for users.
The passkey feature is currently limited to the Facebook mobile app and isn’t yet available on desktop or web browsers. Users logging in from a laptop or desktop will still need to use their username and password for now. Meta has also confirmed that traditional login methods will remain in place as a fallback, allowing access from devices that don’t yet support passkeys.
