eduPersonPrincipalNameStreamline your online collaborations
A scoped identifier for a person. It should be represented in the form "user@scope" where 'user' is a name-based identifier for the person and where the "scope" portion MUST be the administrative domain of the identity system where the identifier was created and assigned. Each value of 'scope' defines a namespace within which the assigned identifiers MUST be unique. Given this rule, if two eduPersonPrincipalName (ePPN) values are the same at a given point in time, they refer to the same person. There must be one and only one "@" sign in valid values of eduPersonPrincipalName. Please refer here for more details.

Syntactically, ePPN looks like an email address but is not intended to be a person's published email address or be used as an email address. In general, name-based identifiers tend to be subject to some degree of expected change and/or reassignment.
Values of eduPersonPrincipalName are often, but not required to be, human-friendly, and may change as a result of various business processes. They may also be reassigned after a locally-defined period of dormancy. Applications that require a guarantee of non-reassignment and more stability, but can tolerate values unfriendly (and unknown) to humans should refer to the eduPersonTargetedID attribute.
