以下是FIDO联盟用户身份验证规范的最新版本。如果您是FIDO的新用户，我们建议您在继续了解之前先阅读“规范概述”。
除了满足技术要求外，FIDO联盟还制定了进一步的安全要求，这些要求必须得到落实，以加强每个设备的安全保证。这些要求包含在认证身份验证器级别页面上的验证器认证计划中。
旧版本的规范和UAF 1.0规范的中文译本可在规范档案中找到。FIDO联盟规范的FIDO规范状态和知识产权（IPR）可在此处查阅。
FIDO联盟发布了以下技术规范，供任何实施者下载。此外，联盟还通过运行fido-dev@fidoalliance.org公共讨论列表，为FIDO身份验证技术的实施者提供支持。如果您有任何关于实施FIDO规范的问题，请在该论坛上提问。
为方便读者，FIDO联盟制作了PDF格式的规范，但如果读者在阅读PDF格式的规范时遇到任何格式问题，建议参考HTML格式的规范。如果您还不是FIDO联盟的成员，并希望对我们的公开规范草案发表意见，请使用联系我们表格。
