Privacy concerns are an important consideration when implementing passkey authentication systems. Key concerns include:\

  • Storage of biometric data: Passkey systems rely on devices' biometric authentication, such as fingerprints or facial recognition. However, biometric data is never transmitted to servers; it remains securely stored on the user's device.
  • Data breaches: Passkeys eliminate the risk of credential theft in large-scale breaches since no passwords are stored on servers. This reduces exposure to attacks.

  • Compliance with regulations: Ensuring that the passkey system aligns with data protection regulations, such as GDPR, is essential to avoid legal risks.
  • User tracking and anonymity: Some users may worry about being tracked across platforms. Passkey systems are designed to prioritize privacy by generating unique credentials for each service, preventing cross-site tracking.

Addressing these concerns through transparent communication and secure system architecture builds trust and confidence among users.
