One or more strong proofs are maintained as associated with an account of a user. In response to a request to change a security setting of the account, an attempt is made to confirm the request by using one of the one or more strong proofs to notify the user. The change is permitted if the request is confirmed via one or more of the strong proofs, and otherwise the change to the security setting of the account is kept unchanged.

Protecting account security settings using strong proofs

Embodiments of authenticating linked accounts are presented herein. In an implementation, an authentication service provides functionality to form links between a plurality of user accounts. A client may then authenticate by providing credentials for one account in a group of linked accounts, and is permitted access to each account in the group of linked accounts based upon the linking. Thus, a single sign-in of a client to one account may permit the client to obtain services for service providers corresponding to multiple linked accounts, without an individual sign-in to each account.
