Abstract

A backup account recovery authentication of last resort using social authentication is described. The account holder requests trustees who have been previously identified to obtain an account recovery code. The account recovery system sends a communication to the trustee for information to verify the trustee as one of the previously identified trustees. The account recovery system then may transmit a link and code with instructions for the trustee to return the link. The account recovery system then transmits a situational query to the trustee to provide additional security. Finally, if all the communications have been completed for the required level of security, the account recovery code is transmitted to the trustee. The trustee sends the account recovery code to the account holder for access to an account.

Claims

1. One or more computer-readable storage devices storing computer-executable instructions that, when executed, configure a computer to perform acts comprising:

receiving, from an account holder of an account with a remote service, identification of a plurality of entities as trustees for an account recovery process for recovering access to the account with the remote service;

subsequent to the initiation of the account recovery process, transmitting, by one or more devices associated with the remote service, a respective account recovery code to each of the plurality of entities identified as trustees for the account, the respective account recovery codes being distinct from one another;

receiving, by the one or more devices associated with the remote service, at least a predefined number of distinct account recovery codes from the account holder over a network;

verifying, by the one or more devices associated with the remote service, the account holder at least in part in response to the receiving of at least the predefined number of distinct account recovery codes of the account recovery codes from the account holder; and

providing account recovery information to the account holder based at least in part on the verifying the account holder.

2. The one or more computer-readable storage devices of claim 1, further comprising, receiving a code to authenticate at least one of the trustees and checking the code against a database record created to track the at least one of the trustees.

3. The one or more computer-readable storage devices of claim 1, wherein each of the account recovery codes is transmitted to a pre-identified contact destination, which includes at least one of the following:

telephone;

e-mail;

or

text message.

4. A method, comprising:

under control of one or more processors of one or more devices associated with a service,

receiving, from an account holder of an account with the service, a designation of a plurality of trustees as trustees for an account recovery process;

receiving, by the one or more devices associated with the service, a request from at least one trustee of the plurality of trustees for an account recovery code, the account recovery code for use by the account holder in conjunction with one or more other account recovery codes sent to other trustees of the plurality of trustees during the account recovery process,

sending, to the at least one trustee, by the one or more devices associated with the service, the account recovery code.

5. The method of claim 4, wherein the account further comprises initial access information for accessing the account and the account recovery process does not recover the initial access information.

6. The method of claim 4, further comprising, prior to sending the account recovery code, transmitting a query to the at least one trustee, the query related to a manner in which the account holder requested the at least one trustee to obtain the respective account recovery code, and sending a warning message to the at least one trustee to enhance security based at least in part on an answer provided in response to the query.

7. The method of claim 4, further comprising, prior to sending the account recovery code, transmitting, to the at least one trustee, a query;

and

transmitting, to the at least one trustee, a warning message based at least in part on an answer provided in response to the query, the warning message providing the at least one trustee with information to assist at least in part in determining whether or not to proceed with the acquisition of the account recovery code.

8. The method of claim 4, further comprising receiving, from the account holder a request to abort the acquisition of the remaining account recovery codes if the account holder discovers an unauthorized attempt to obtain a first account recovery code before all of the account recovery codes have been received.

9. The method of claim 6, further comprising receiving, from the at least one trustee, an electronic signature indicating that the trustee decides to proceed with the acquisition of the account recovery code after receiving the warning message, the electronic signature providing authorization to proceed.

10. The method of claim 6, further comprising receiving, from the at least one trustee, a request to abort the acquisition of the account recovery code indicating that the at least one trustee decides not to proceed with the acquisition of the account recovery code after receiving the warning message.

11. The method of claim 6, further comprising:

subsequent to sending the warning, determining a probability that the at least one trustee is operating on behalf of the account holder; and

using a processor of the one or more devices associated with the service executing processor-executable instructions to determine whether to send the respective account recovery code to the trustee based at least in part on the determined probability.

12. A system, comprising:

under control of one or more processors of one or more devices associated with a first entity configured with specific executable instructions,

receiving, from an account holder of an account with the first entity, identification of a plurality of second entities as trustees for an account recovery process;

receiving a request to initiate the account recovery process;

subsequent to the initiation of the account recovery process, transmitting, by the one or more devices associated with the first entity, a respective account recovery code to at least two of the plurality of second entities identified as trustees for the account;

receiving, from the account holder, at least a predefined number of distinct account recovery codes of the account recovery codes; and

verifying, by the one or more devices associated with the first entity, the account holder at least in part in response to the receiving of at least the predefined number of distinct account recovery codes of the account recovery codes from the account holder.

13. The system of claim 12, wherein verifying the account holder based at least in part on receipt of at least the predefined number of the distinct account recovery codes from the account holder comprises receiving at least three of the distinct account recovery codes from the account holder, each of the at least three account recovery codes having been transmitted to a respective one of at least three separate trustees for the account.

14. The system of claim 12, wherein receiving, from the account holder of the account, identification of the plurality of second entities as trustees for the account recovery process comprises receiving identification of at least three second entities as trustees for the account recovery process.

15. The system of claim 12, further comprising transmitting a notification with the account recovery codes that the trustees are to deliver the account recovery codes to the account holder by using one or more specified communication mediums, at least one of the one or more specified communication mediums including at least a telephone call.

16. The system of claim 12, further comprising transmitting a notification with the account recovery codes that the trustees are not to deliver the account recovery codes to the account holder by using one or more specified communication mediums, the one or more specified communication mediums including at least electronic mail.

17. The system of claim 12, further comprising, during the account recovery process,

receiving a request from each of at least two of the plurality of second entities identified as a trustee for the account for a respective account recovery code;

and

for each trustee requesting an account recovery code;

transmitting a verification form to the trustee for authentication;

receiving the verification form from the trustee after the verification form is completed by the trustee;

identifying the trustee by comparing the verification form as completed by the trustee with information stored in a database;

transmitting a code to authenticate the trustee to a pre-identified contact destination;

receiving the code from the trustee to authenticate the trustee;

transmitting a query to the trustee;

receiving a response to the query from the trustee; and

transmitting the respective account recovery code to the trustee for delivery to the account holder.

18. The system of claim 17, wherein receiving a code to authenticate the at least one of the trustees further comprises checking the code against a database record created to track the at least one of the trustees.

19. The system of claim 12, wherein the respective account recovery codes are generated by the one or more devices associated with the first entity.

20. The system of claim 12, wherein the receiving, from the account holder over the network, at least the predefined number of distinct account recovery codes of the account recovery codes comprises:

providing a user interface by which to receive at least the predefined number of distinct account recovery codes; and

receiving, over the network, the distinct account recovery codes received by the user interface.
