LOA 的四個級別

Levels of Assurance

What are Levels of Assurance (LOA)? 什麼是擔保級別？

1 - Basic Identity

用戶名 This level deals with a username, User Principle Name (UPN), or email address alone.

2 - Proven Identity

用戶名 + 密碼 This level requires that the user prove their identity by authenticating with a password.

3 - Proven ID with multi-factor authentication

除了密碼以外，還須提供另外一認證要素，好比一次性密碼 In additional to a password the user must prove their identity with another factor of authentication such as a one time password (OTP).

4 - Strong ID with physical token multi-factor authentication

使用物理認證方法，好比指紋識別或虹膜識別等生物測定。 This level requires that a user authenticate using a physical method such as biometrics.
