Now, things are easier than ever with biometric login and secure authentication using passkeys. This blog will cover what passkeys are, how passkeys with Face ID and Touch ID work on your devices, and the benefits of using both together.\u00a0<\/span><\/p>\n<blockquote><p><b>NOTE:<\/b><span style=\"font-weight: 400;\"> FastestPass is a dedicated password manager that syncs all your complex passwords across devices without you having to remember all of them, but just one master password. Now, you can also sync your passkeys across devices to ensure seamless security across every device, especially when logging in to the apps across your smart devices.\u00a0<\/span><\/p><\/blockquote>\n<p><span style=\"font-weight: 400;\">    <div class=\"fastestpass-hd-btn\">\n    <a class=\"hd-conter-btn\" href=\"https:\/\/fastestpass.com\/pricing\" title=\"Get FastestPass\">Get FastestPass <i class=\"fa fa-hand-o-right\" aria-hidden=\"true\"><\/i><\/a>\n    <\/div>\n<\/span><\/p>\n<h2><b>What are Passkeys?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Passkeys are passwordless login credentials based on public\u2011key cryptography, created under the FIDO2\/WebAuthn standards.\u200b<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A public key is stored with the website or app.\u200b<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A private key stays safely on your device and never leaves it.\u200b<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">When you log in, the site sends a cryptographic challenge that only your private key can answer, eliminating shared secrets like passwords that can be phished or leaked.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Passkeys replace traditional passwords with cryptographic key pairs securely stored on your devices. When you sign in, your device signs a cryptographic challenge using its private key\u2014there\u2019s no password to type, remember, or steal. This system works smoothly on devices equipped with biometrics, such as Face ID or Touch ID, ensuring your key is only accessible to you.<\/span><\/p>\n<h2><b>Are Passkeys and Face ID the same?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">No, in short, passkeys and <a href=\"https:\/\/support.apple.com\/en-us\/102381\">Face ID<\/a> aren\u2019t the same. However, Face ID can be used as a passkey. To double down on it, a passkey is an authentication mechanism that needs your Face ID or Touch ID to access a particular website or app, making it legit that it is, in fact, you who is trying to open that website or app, and no one else.\u00a0<\/span><\/p>\n<h2><b>Face ID vs Passkeys: What\u2019s the Difference?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Face ID and passkeys are not the same thing, but they work together.\u200b<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Face ID \/ Touch ID: biometric systems that verify that you are holding the device.\u200b<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Passkeys: the actual cryptographic credentials used to authenticate you to a website or app.\u200b<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In practice, Face ID passkey authentication looks like \u201clook at your phone, and you\u2019re in,\u201d but under the hood, Face ID is just unlocking the private key that completes the login.<\/span><\/p>\n<h2><b>How Passkeys Work with Face ID<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Understanding how passkeys work with Face ID helps explain why the experience feels both simple and secure.\u200b<\/span><\/p>\n<h3><b>1.

Login: Face ID Unlocks the Passkey<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">During sign\u2011in, how passkeys work with Face ID follows a simple flow:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">You open the app or site and select your account; the browser or app asks the OS to use your passkey.\u200b<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Your iPhone displays the system prompt to scan your face with Face ID.\u200b<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">After Face ID verifies you, iOS unlocks the private key and uses it to sign the cryptographic challenge from the service.\u200b<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The signed response proves to the service that \u201cthe same device and user are present,\u201d and you\u2019re logged in, without any password.\u200b<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">So, how passkeys use Face ID and Touch ID to authenticate is by treating biometrics as the \u201ckey to the key\u201d: Face ID verifies the user locally, then the passkey authenticates you to the remote service.\u200b<\/span><\/p>\n<h2><b>How Passkeys Work with Touch ID<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">On compatible iPhone, iPad, and Mac models, how passkeys work with Touch ID is almost identical to Face ID, just with a fingerprint sensor instead of facial recognition.\u200b<\/span><\/p>\n<h3><b>1.
