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:
establishing a peer-to-peer ad-hoc communication link between a first device and a second device, wherein the first device does not have authentication data for communicating with a network;
sending via the peer-to-peer ad-hoc communication link, by the first device, a request for authentication data from the 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 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 on the network.

2. The method of claim 1 , wherein receiving authentication data from the second device at the first 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 , wherein establishing communication comprises:
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 1 , wherein the second communication link comprises a personal area network (PAN).

5. The method of claim 1 , 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 5 , comprising establishing the peer-to-peer ad-hoc communication link with the second device based at least in part on whether the second device is located proximate to the first device.

7. An electronic device, comprising:
a computer processor configured to:
establish a peer-to-peer ad-hoc communication link between a first device and a second device, wherein the electronic device does not have authentication data for communicating with a network;
send, via the peer-to-peer ad-hoc communication link, a request for authentication data from the second device;
receive authentication data from the second electronic device via the peer-to-peer ad-hoc communication link, wherein the authentication data was previously used by the second electronic device to communicate with the network; and
transmit 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 electronic device on the network.

8. The electronic device of claim 7 , wherein the processor is configured to communicate with a cloud-based service on the network.

9. The electronic device of claim 7 , 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.

10. The electronic device of claim 7 , 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.

11. The electronic device of claim 7 , wherein the processor is configured to scan for one or more communication links.

12. The electronic device of claim 7 , wherein the processor is configured to obtain access to the network upon transmitting authentication data.

13. A non-transitory computer-readable medium having computer executable code stored thereon, the code comprising instructions to:
establishing a peer-to-peer ad-hoc communication link between a first device and a second device, wherein the first device does not have authentication data for communicating with a network;
sending, via the peer-to-peer ad-hoc communication link, by the first device, a request for authentication data from the second device;
receiving authentication data from the second device at the first 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 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 on the network.

14. The non-transitory computer-readable medium of claim 13 , wherein the code comprises instructions to cause the second device to access the network prior to the first device accessing the network.

15. The non-transitory computer readable medium of claim 13 , wherein the code comprises instructions to cause the second device to terminate a session established between the second device and a cloud based service on the network.

16. The non-transitory computer readable medium of claim 13 , wherein the second communication link comprises a personal area network (PAN).
