Abstract: Disclosed herein are methods for protecting user information on a client device that may have a plurality of users. A user interface with a public machine designation portion is presented to a user prior to the start of the authentication process. The public machine designation removes web service account descriptions and any user specific information stored on the client device. Also, the client device is prevented from storing any new user specific information that is provided to the client device. The public machine designation is a persistent feature that may only be disabled by an affirmative action from the user.

Abstract: Embodiments of multi-user web service sign-in client side components are presented herein. In an implementation, the currently authenticated user account of a first application of a client is transferred to another application of a client. In another implementation, a common credential store is used to share data for a plurality of user accounts associated with a client between a plurality of applications of the client, and for the applications to output multi-user interfaces having portions corresponding to the plurality of accounts.

Abstract: An integrated authentication service is described which may receive a bundled request from one or more clients. One or more of the described techniques may be utilized to provide, in response to a single bundled request, a token for proof of identity and a certificate for establishing secure communications.

Abstract: Embodiments of multiple security token transactions are described herein. One or more of the described techniques may be utilized to provide, in a single request and response, an authentication token and a plurality security tokens for proof of identity at respective service providers.

Abstract: Embodiments of proxy authentication and indirect certificate chaining are described herein. In an implementation, authentication for a client occurs via a proxy service. Proxy service communicates between client and server, and caches security tokens on behalf of the client. In an implementation, trustworthiness of certificate presented to a client to establish trust is determined utilizing a signed data package which incorporates a plurality of known certificates. The presented certificate is verified without utilizing root certificates installed on the client device.

Abstract: Techniques are described which may be employed to provide a login screen with identifying data. In an implementation, a login screen is displayed having an image that identifies a user. Credentials are received via the login screen to log the user onto a service provider over a network.

Abstract: A human interactive proof (HIP) service is described. In response to a request from a web server, the HIP service generates a HIP challenge and an associated attestation. The web server can then embed the generated HIP challenge in a requested web page. The attestation is used to determine whether or not a user response to the HIP challenge is correct.
