PassKey Vault is a Chrome browser extension designed for secure storage and management of passkeys using the WebAuthn API. The extension efficiently intercepts WebAuthn API calls, allowing users to manage their passkeys without displaying the browser's native user interface. This functionality enhances user experience by streamlining the authentication process while ensuring security. It is compatible with both Chrome (Manifest V3) and Firefox (Manifest V2), making it versatile for different users.

Key features of PassKey Vault include automatic interception of passkey creation and authentication, ensuring that users can easily access their stored credentials. Additionally, the extension utilizes local storage to securely keep passkeys within the browser, protecting sensitive information from unauthorized access. Users can also benefit from the export and import functionality, allowing for a complete backup of their passkeys with encrypted private keys for enhanced security.
