3. The method of claim 1 , wherein determining whether the user input is inconsistent with the active user profile comprises:

determining a receipt time of the user input;

retrieving a plurality of receipt times for the previously received user inputs;

determining a usage period of the device based on the plurality of receipt times;

determining whether the receipt time of the user input is within the usage period of the device; and

in response to determining that the receipt time is not within the usage period, determining that the user input is inconsistent with the active user profile.

4. The method of claim 1 , wherein identifying the second device that is located within the threshold distance of the first location further comprises selecting the second user from a list of candidate users in the active user profile of the device, wherein the list of candidate users is:

a list of social media friends associated with an owner of the device,

a list of contacts stored on the device, or

a list of owners of the device.

5. The method of claim 4 , wherein selecting the second user from the list of candidate users comprises:

identifying a first candidate user from the list of candidate users;

retrieving location information of the first candidate user;

determining whether the location information matches the first location; and

in response to determining that the location information matches the first location, selecting the first candidate user as the second user.

6. The method of claim 1 , wherein location information of the first second user is retrieved from any one of:

a social media profile of the second user,

metadata of media uploaded to a website by the second user,

a message on the device received from the second user,

a global-positioning system (GPS) tracker on the second device, and

a travel record of the second user.

7. The method of claim 1 , further comprising:

receiving an additional user input on the device from the second user;

updating the temporary active user profile based on the additional user input; and

sending a copy of the updated temporary active user profile to the second device.

8. The method of claim 1 , wherein the user input is a search command for a media asset and wherein comparing the user input with the active user profile comprises:

determining a genre of the media asset;

determining, from previously received user inputs in the active user profile, whether a prior search for a different media asset that shares the genre exists;

in response to determining that the prior search for the different media asset that shares the genre does not exist, determining that the user input is inconsistent with the active user profile.

9. The method of claim 1 , further comprising:

in response to determining that the user input is not consistent with the user profile of the second user, selecting a different candidate user from a list of candidate users on the active user profile.

10. The method of claim 1 , further comprising:

generating, for display on the device, a query to confirm whether the user input was received from the second user;

in response to receiving a confirmation to the query, activating the user profile of the second user as the temporary active user profile on the device.

11. A system for identifying a user profile for temporary use on a device, the system comprising:

user input interface configured to:

receive a user input on a first device, wherein the first device is in a first location;

control circuitry configured to:

compare the user input with an active user profile, of a first user, on the first device; and

in response to determining, based on the comparing, that the user input is inconsistent with the active user profile:

detecting that a second device is located within a threshold distance of the first location, wherein the second device is associated with a second user different from the first user;

determine whether the user input received on the first device is consistent with a user profile of the second user associated with the second device detected within the threshold distance of the first location; and

in response to determining that the user input is consistent with the user profile of the second user, activate the user profile of the second user as a temporary active user profile on the first device.

12. The system of claim 11 , wherein the control circuitry is configured to determine whether the user input is inconsistent with the active user profile by:

identifying previously received user inputs on the active user profile;

determining whether the user input matches any of the previously received user inputs on the active user profile; and

in response to determining that the user input does not match any of the previously received user inputs on the active user profile, determining that the user input is inconsistent with the active user profile.

13. The system of claim 11 , wherein the control circuitry is configured to determine whether the user input is inconsistent with the active user profile by:

determining a receipt time of the user input;

retrieving a plurality of receipt times for the previously received user inputs;

determining a usage period of the device based on the plurality of receipt times;

determining whether the receipt time of the user input is within the usage period of the device; and

in response to determining that the receipt time is not within the usage period, determining that the user input is inconsistent with the active user profile.

14. The system of claim 11 , wherein the control circuitry is configured to identify the second device that is located within the threshold distance of the first location further by selecting the second user from a list of candidate users in the active user profile of the device, wherein the list of candidate users is:

a list of social media friends associated with an owner of the device,

a list of contacts stored on the device, or

a list of owners of the device.

15. The system of claim 14 , wherein the control circuitry is configured to select the second user from the list of candidate users by:

identifying a first candidate user from the list of candidate users;

retrieving location information of the first candidate user;

determining whether the location information matches the first location; and

in response to determining that the location information matches the first location, selecting the first candidate user as the second user.

16. The system of claim 11 , wherein location information of the second user is retrieved from any one of:
