<ul data-eligibleForWebStory="true">Facebook is introducing passkey support on its mobile app for enhanced security against phishing attacks.Passkeys allow users to log in using fingerprint, face scan, or PIN, making it harder for unauthorized access.Passkeys are more secure than traditional passwords as they can't be stolen or leaked, providing protection against phishing scams.Browser integration with passkeys ensures they only work on genuine domains and not on fake login pages.Meta, Facebook's parent company, plans to launch passkey support on Android and iOS soon, extending to the Messenger app as well.Various big tech companies like Google, Microsoft, Apple, and WhatsApp already use passkeys for secure sign-ins.Users can still utilize passwords, physical security keys, or two-factor authentication in addition to passkeys for logging in.In addition to account logins, passkeys can be used for autofilling payment information on Meta Pay.
