Abstract: Single sign-on techniques via an application or browser are described. In one or more implementations, a single instance of entry of authentication information is received that is entered via interaction with an application or browser of a computing device. Responsive to this receipt, the single instance of the entry of authentication information is used by the computing device automatically and without user intervention to cause authentication to obtain access to one or more network services that are accessible via a network by the application and the browser.

Abstract: The techniques discussed herein may facilitate user account management while also protecting a user's personally identifiable information (PII). The user's PII is stored in a protected area, such as a secure operating system area. The techniques may also implement a broker process to access a user's PII. The techniques display a user's accounts that are available for use with an application. The techniques further provide for passing a hint to the application upon receiving selection of an account, wherein the hint indicates which user account is selected, without divulging to the application any of the user's PII.

Abstract: A data structure that represents a person is created. The data structure comprises a person object. The person object comprises one or more contact objects. When it is determined that the person is a global address list contact, first contact information for the person is obtained from a global address list store and stored in a first contact object. When it is determined that the person is an email contact, second contact information is obtained from a contact store and stored in a first memory cache. When it is determined that the second contact information includes a global address identifier, the global address identifier is stored in the second contact object. A person identifier is created for the person that identifies the person. The person identifier is stored in the first contact object and in the second contact object.
