Strong Identity Authentication

Another example of the network effect's positive impact on identity management is Google's implementation of strong two-factor authentication for Google Apps.

另一个网络效应为身份管理带来正面影响的例子是Google在Google应用里实施的强双重认证。

When combined with the identity fabric, however, the benefit of strong authentication can expand across the network.

可是当与其他身份结构结合时，强认证的益处就扩大到整个网络。

Finally, there is strong authentication in which an identity is verified using two or more methods, such as a password and a cryptographic key.

最后是强身份验证，其中使用两种或者更多的方法对一个标识进行验证，如密码和加密密钥。
