Protect your SMB clients from synced passkey attacks
MSPs and IT service providers need a clear way to protect SMBs from synced passkey attacks targeting exportable, cloud-synced credentials. Recent research reported in Hacker News shows attackers can hijack synced passkeys through the browser layer, then register attacker-controlled keys, downgrade prompts, or trick users into re-enrollment. In short: if a passkey can be copied between devices (via Apple or Google clouds, or a password manager), a compromised browser or account recovery flow can put your clients at risk.
What synced passkey attacks mean for SMBs
- Target: multi-device (synced) passkeys that live in platform or manager clouds.
- Technique: extension/script or malicious flow hijacks WebAuthn, inserts a new key, and exfiltrates it.
- Impact: unauthorized access to SaaS and cloud apps (even with biometrics in the loop) if the passkey is exportable. (Cybernews)
How Okta + ZeroTek help MSPs protect SMBs from synced passkey attacks
With Okta delivered through ZeroTek, MSPs standardized on phishing-resistant, device-bound authenticators (Okta FastPass and FIDO2/WebAuthn security keys), and to disable weak authenticators (SMS, email, voice). That baseline removes the dependency on consumer passkey sync clouds while raising the bar on assurance.
What ZeroTek Partners enforce today with Okta
- Device-bound authenticators by default. Use FastPass (with on-device biometrics/PIN and cryptographic binding) and FIDO2 security keys.
- No weak factors. Disallow (SMS/email/TOTP) for workforce logins; require phishing-resistant MFA.
- Strong authentication policies. Mandate user verification = required and possession factor = phishing-resistant for sensitive resources and the Okta Admin Console.
- Attestation and device assurance. Gate access on device signals (OS version, patch level, disk encryption, jailbreak/root status) and require trusted device registration. These checks run at sign-in: no green device, no access.
- Threat-aware controls. Combine the above with Okta risk signals and sign-on policy rules to step up or block as needed. ZeroTek provides detailed, field-tested best practices for Okta policy configurations to our Partners as well as comprehensive support to deploy Okta successfully every time.
The bottom line for MSPs
To protect SMBs from synced passkey attacks, anchor authentication to device-bound authenticators. With Okta delivered through ZeroTek, IT service providers and MSPs protect their SMB customers by rolling out phishing-resistant MFA, enforcing device posture, and keeping authenticator keys anchored to trusted hardware, so there’s no reliance on Apple or Google passkey sync to protect access. If you must allow passkeys, Okta gives you the ability to block multi-device passkeys and stick to hardware-backed, device-bound options.
