WebAuthn Client是否必须为网页浏览器？能否是命令行界面应用？

WebAuthn clients do not require a web browser—command-line interface (CLI) applications are fully capable of implementing WebAuthn for passwordless authentication.

If you’re focused on building a CLI app for passwordless auth using first-factor roaming authenticators (such as fingerprint sensors or biometric security keys), this is entirely feasible. CLI apps can interact with these authenticators via cross-platform libraries or platform-specific APIs that comply with the WebAuthn standard. These tools handle the communication between your app and the authenticator, including triggering user verification steps (like biometric scans or PIN entry) required for passwordless multi-factor authentication.

用户验证平台认证器与第一因子漫游认证器支持无密码多因素认证。除了凭证私钥持有证明外，这些认证器还支持将用户验证作为第二认证因子，通常为PIN或生物识别。因此，该认证器可充当两类认证因子，无需向依赖方共享密码即可实现多因素认证。

Developers can use open-source WebAuthn client libraries (for languages like Go, Python, or Rust) to build CLI tools that handle both registration and authentication flows without relying on a browser. This makes passwordless auth accessible for use cases like server management, CLI-based service logins, or version control system authentication.
