In cybersecurity, convenience often comes at a cost. Synced passkeys\u2014touted for their ability to work seamlessly across multiple devices\u2014are a prime example. While they simplify access, recent research shows they can introduce serious vulnerabilities, potentially exposing entire organizations to risk.<\/p>\n
Fortunately, there\u2019s a secure alternative that delivers the passwordless experience we want\u2014without compromising safety. Let\u2019s explore why synced passkeys can be dangerous and why device-bound FIDO2 passkeys are the superior choice.<\/p>\n
Simply put, a passkey is like a password\u2014but far more secure. Instead of a string you memorize, it\u2019s a cryptographic key stored on your device. Passkeys rely on a pair of keys:<\/p>\n
Public Key:<\/strong> Shared with the service you\u2019re accessing (like your bank or email).<\/p>\n<\/li>\n Private Key:<\/strong> Stored securely on your device and never leaves it.<\/p>\n<\/li>\n<\/ul>\n Using modern asymmetric cryptography, passkeys are much harder to steal or guess than traditional passwords.<\/p>\n Passkeys are an excellent way to implement passwordless multi-factor authentication (MFA). Here\u2019s how it works:<\/p>\n Your private key is stored in a secure location, such as the secure chip on your phone\u2014or, ideally, a dedicated FIDO2 device.<\/p>\n<\/li>\n To log in, you verify your identity with a PIN or biometric factor.<\/p>\n<\/li>\n The device then performs a cryptographic handshake with the service.<\/p>\n<\/li>\n Crucially, the private key never leaves your device, making phishing attacks virtually impossible.<\/p>\n<\/li>\n<\/ul>\n The key difference lies in where the private key is stored:<\/p>\n Synced Passkeys:<\/strong> Stored in the cloud and synced across all trusted devices. Convenient, yes\u2014but this expands the attack surface. If attackers compromise the syncing process, they could impersonate users.<\/p>\n<\/li>\n Device-Bound Passkeys (FIDO2):<\/strong> Generated and stored on a single hardware token (like a USB key or smart card). The key cannot be exported, copied, or synced.<\/p>\n<\/li>\n<\/ul>\n Research from companies such as SquareX and presentations at DEF CON have already shown attacks like JavaScript injection and \u201cSigned Assertion Hijacking\u201d targeting synced passkeys. Simply put, synced passkeys are an attractive target.<\/p>\n The safest approach is clear: FIDO2 device-bound passkeys. By pairing a hardware key with a biometric or PIN, you create a phishing-resistant, uncompromisable authentication method. Since the private key never leaves the hardware, it cannot be stolen remotely or synced to an attacker\u2019s device.<\/p>\n vSEC:CMS enables organizations to deploy and manage FIDO2 hardware keys at scale. Unlike synced passkeys, this approach ensures:<\/p>\n Rock-Solid Security:<\/strong> Eliminates the vulnerabilities associated with synced keys.<\/p>\n<\/li>\n Centralized Management:<\/strong> IT admins can fully control issuance, revocation, and device lifecycles.<\/p>\n<\/li>\n Full FIDO2 Capabilities:<\/strong> Supports bulk issuance and advanced device management features.<\/p>\n<\/li>\n<\/ul>\n Passkeys are the future of authentication\u2014but implementation matters. While synced passkeys may seem convenient, the risks are too high for security-conscious organizations. Device-bound FIDO2 passkeys provide the perfect combination of security, control, and usability.<\/p>\n With vSEC:CMS, organizations can transition to this secure, passwordless future confidently and efficiently\u2014ensuring robust authentication without compromise.<\/p>\n <\/p>\n About DT Asia<\/strong><\/p>\n DT Asia began in 2007 with a clear mission to build the market entry for various pioneering IT security solutions from the US, Europe and Israel.<\/p>\n Today, DT Asia is a regional, value-added distributor of cybersecurity solutions providing cutting-edge technologies to key government organisations and top private sector clients including global banks and Fortune 500 companies.
