Passkeys are being promoted as the next step in authentication, a way to eliminate passwords for good. But if they are not configured properly, they can be just as easy for attackers to exploit.
Many MSPs are rolling out passkeys without realizing that a single misconfiguration can leave clients exposed to token hijacking, phishing, and unauthorized access.
We see it all the time in security assessments—passkeys alone don’t make a system secure. They require the right controls to prevent attackers from bypassing authentication entirely.
The key question is: Are your clients actually more secure, or are you just giving attackers a new way in?
How Hackers Exploit Passkeys
Passkeys rely on authentication tokens instead of passwords. The problem? Hackers don’t need to crack a password if they can steal or replicate the token.
Once they have access, they move undetected, bypassing traditional security measures. If your MSP isn’t securing passkeys correctly, attackers can slip right in—without triggering alerts.
How MSPs Must Secure Passkeys
Each step in securing passkeys is connected. Skip one, and you leave an open door for attackers.
Here’s what your MSP needs to focus on:
- Implement Strong MFA Controls
- Enforce multi-factor authentication across all systems.
- Require hardware-based security keys like YubiKeys for added protection.
- Validate Identity Provider (IdP) Settings
- Check Azure AD, Okta, or any IdP configurations to ensure secure token issuance and storage.
- Disable weak authentication policies that could leave tokens exposed.
- Enable Device-Based Security
- Require device encryption and endpoint detection to prevent attackers from stealing tokens from compromised machines.
- Turn Off Legacy Authentication
- Eliminate password fallbacks (like email-based account recovery) that could allow attackers to bypass passkeys.
- Audit Access Logs Regularly
- Look for repeated token refresh requests or unexpected access attempts from new devices.
- Educate Clients on Token Security
- Train users on the risks of token theft, phishing attacks, and compromised devices.
Passkey Security: A Process, Not Just a Setting
Passkeys offer a strong alternative to passwords, but only if they are configured and managed properly.
Fail to lock them down, and you introduce new vulnerabilities instead of solving old ones.
