AccountManager on Windows Phone 7

Question

Is there an AccountManager on Wp7 similiar to the one in Android? So I can use the phone's already authenticated Google account as openID or something (login to my service without asking for his password).

EDIT to add: I have an Active Directory of users, I know their email addresses. (Including their live id if needed, would have preferred Gmail though) I want to be able to login a user without asking for any password, based on authenticated accounts available on his phone.

You can use Live ID.

In manifest:

<Capabilities>
      ...
      <Capability Name="ID_CAP_IDENTITY_DEVICE"/>
      <Capability Name="ID_CAP_IDENTITY_USER"/>
   < /Capabilities>


using Microsoft.Phone.Info;

string anid = UserExtendedProperties.GetValue("ANID") as string;
string anonymousUserId = anid.Substring(2, 32);

Details here.

So you can get a combination of Live Id and Device id to identify the user+device.
