What are some Potential Drawbacks of Passkeys?#

Passkeys offer enhanced security, but they come with potential drawbacks, such as requiring specific hardware (hardware security modules like a TPM, Secure Enclave or TEE) and facing challenges with cross-device platform compatibility.

Understanding the Potential Drawbacks of Passkeys#

While passkeys represent a significant step forward in secure user authentication, they are not without their challenges. Below, we explore the main drawbacks associated with passkeys:

1. Hardware Requirements#

• Passkeys rely on hardware security modules, such as Trusted Platform Modules (TPMs), Secure Enclaves or Trusted Execution Environments (TEE).
• Users must have compatible devices with the necessary hardware features, which might not be universally available.
• This requirement can limit accessibility, especially in cases where users rely on older devices or lack access to high-end technology.

2. Cross-Device Platform Challenges#

• Cross-device authentication can be difficult to implement, particularly in environments with diverse operating systems and hardware configurations.
• Users often switch between devices, such as moving from a smartphone to a laptop. Ensuring that passkeys work seamlessly across these platforms requires careful integration.
• While solutions like Corbado streamline this process, it still represents a significant technical hurdle for many developers.

3. Adoption and User Experience Concerns#

• Despite the security benefits, some users may find the transition to passkeys confusing or inconvenient, particularly if they are accustomed to traditional password systems.
• There may be resistance from users who are wary of relying entirely on biometric data for access, raising concerns about privacy and data security.

When considering the implementation of passkeys, it is essential to weigh these drawbacks against the security advantages they offer. For developers and product managers, understanding these challenges is key to creating a smooth user experience while maintaining robust security protocols.

About Corbado

Corbado is the Passkey Intelligence Platform for CIAM teams running consumer authentication at scale. We help you see what IDP logs and generic analytics tools can't: which devices, OS versions, browsers and credential managers support passkeys, why enrollments don't turn into logins, where the WebAuthn flow fails and when an OS / browser update silently breaks login, all without replacing Okta, Auth0, Ping, Cognito or your in-house IDP. Two products: Corbado Observe layers observability for passkeys and any other login method. Corbado Connect adds managed passkeys with analytics built in (alongside your IDP). VicRoads runs passkeys for 5M+ users with Corbado (+80% passkey activation). Talk to a Passkey Expert →
