Abstract

Arrangements described herein relate to accessing a cloud based service. Responsive to a user of a first communication device initiating access to the cloud based service via the first communication device, a prompt for a valid password to be entered to access the cloud based service can be received by the first communication device. Responsive to the valid password required to access the cloud based service not being stored on the first communication device, the first communication device can automatically retrieve the valid password from a second communication device via a peer-to-peer ad hoc communication link between the first communication device and the second communication device. The valid password can be automatically provided, by the first communication device, to a login service for the cloud based service to obtain access by the first communication device to the cloud based service.

First claim

The invention claimed is:

1. A method, comprising:
determining that a first device is located proximate to a second device, wherein the first device does not have authentication data for a cloud-based service accessible via a network;
based at least in part on the determination that the first device is located proximate to the second device, establishing a peer-to-peer ad-hoc communication link between a first device and a second device;
receiving, by the first device, authentication data from the second device via the peer-to-peer ad-hoc communication link, wherein the authentication data was previously used by the second device to communicate with the network; and
transmitting the authentication data from the first device, via a second communication link that is different from the peer-to-peer ad-hoc communication link, to the network to authenticate the first device for the cloud-based service.

2. The method of claim 1 , wherein receiving authentication data from the second device comprises:
requesting authentication data from the second device by the first device; and
delivering authentication data from the second device to the first device when the second device has authentication data.

3. The method of claim 1 , further comprising:
transmitting, from the first device, a request to access the network; and
receiving, from the network, a request for authentication data in response to the request to access the network of the first device.

4. The method of claim 3 , further comprising:
after receiving the request for authentication data at the first device, sending, via the peer-to-peer ad-hoc communication link, by the first device, a request for authentication data from the second device.

5. The method of claim 1 , further comprising establishing the peer-to-peer ad-hoc communication link with the second device upon determining that the authentication data is not stored on the first device.

6. The method of claim 1 , wherein determining that the first device is located proximate to the second device comprises determining that a personal area network (PAN) link is or can be established between the first device and the second device.

7. The method of claim 6 , wherein determining that a PAN link is or can be established between the first device and the second device comprises determining that the first device and the second device are both part of a common PAN.

8. The method of claim 1 , wherein determining that the first device is located proximate to the second device comprises determining that a near field communication (NFC) link is or can be established between the first device and the second device.

9. The method of claim 1 , further comprising:
determining, by the first device, that the first device does not have authentication data for the cloud-based service; and
responsive to determining that the first device does not have authentication data for the cloud-based service, the first device automatically requesting the authentication data from the second device.

10. An electronic device comprising:
a computer processor configured to:
determine that a first device is located proximate to a second device, wherein the first device does not have authentication data for a cloud-based service accessible via a network;
based at least in part on the determination that the first device is located proximate to the second device, establish a peer-to-peer ad-hoc communication link between a first device and a second device;
receive, by the first device, authentication data from the second device via the peer-to-peer ad-hoc communication link, wherein the authentication data was previously used by the second device to communicate with the network; and
transmit the authentication data from the first device, via a second communication link that is different from the peer-to-peer ad-hoc communication link, to the network to authenticate the first device for the cloud-based service.

11. The electronic device of claim 10 , wherein the processor is configured to determine validity of authentication data based at least in part on one or more time stamps associated with authentication data.

12. The electronic device of claim 10 , wherein the processor is configured to:
request authentication data from the second device; and
receive authentication data from the second device when the second device has authentication data.

13. The electronic device of claim 10 , wherein the processor is configured to determine that the first device is located proximate to the second device at least in part by determining that a personal area network (PAN) link is or can be established between the first device and the second device.

14. The electronic device of claim 10 , wherein the processor is configured to determine that the first device is located proximate to the second device at least in part by determining that a near field communication (NFC) link is or can be established between the first device and the second device.

15. A non-transitory computer-readable medium having computer executable code stored thereon, the code comprising instructions for:
determining that a first device is located proximate to a second device, wherein the first device does not have authentication data for a cloud-based service accessible via a network;
based at least in part on the determination that the first device is located proximate to the second device, establishing a peer-to-peer ad-hoc communication link between a first device and a second device;
receiving, by the first device, authentication data from the second device via the peer-to-peer ad-hoc communication link, wherein the authentication data was previously used by the second device to communicate with the network; and
transmitting the authentication data from the first device, via a second communication link that is different from the peer-to-peer ad-hoc communication link, to the network to authenticate the first device for the cloud-based service.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions for determining that the first device is located proximate to the second device comprise instructions for determining that a personal area network (PAN) link is or can be established between the first device and the second device.

17. The non-transitory computer-readable medium of claim 15 , wherein the instructions for determining that a PAN link is or can be established between the first device and the second device comprise instructions for determining that the first device and the second device are both part of a common PAN.

18. The non-transitory computer-readable medium of claim 15 , wherein the instructions for determining that the first device is located proximate to the second device comprise instructions for determining that a near field communication (NFC) link is or can be established between the first device and the second device.
