To meet these stronger security needs, either multi-layer authentication or multifactor authentication or combinations of both are used.
2
实现多因素身份验证的系统应该对不同的因素使用不同的底层安全机制。
The systems implementing multifactor authentication should make sure that they use different underlying security mechanisms for different factors.
3
这种技术组合可以降低使用相同底层安全机制实现多因素身份验证解决方案的风险。
This combination helps reduce the risks associated with systems exercising multifactor authentication solutions using the same underlying security mechanism.
