Methods and systems of adding a user account to a device

1. A method of adding a user account to an unassociated device, the method comprising:

sending, by an unassociated device that is not associated with a user account, a request to a computing device associated with a service provider of the user account, wherein the request comprises device information associated with the unassociated device;

receiving, by the unassociated device from the computing device, a token;

broadcasting, by the unassociated device, an audio signal that comprises the received token;

detecting, by a receiver of an associated device that is associated with the user account, the audio signal;

sending by the associated device to the computing device associated with the service provider:

the token, and

one or more authorization instructions that instruct the computing device to send one or more credentials for the user account to the unassociated device,

receiving, by the unassociated device, the one or more credentials associated with the user account from the computing device; and

using the received credentials to add the user account to the unassociated device.

2. The method of claim 1 , wherein the audio signal comprises an ultrasound signal.

3. The method of claim 1 , wherein receiving one or more credentials comprises receiving one or more credentials via one or more of the following:

a short-range communication; and

an OAuth token.

4. The method of claim 1 , further comprising:

creating an audio recording of an environment of the associated device;

generating an audio fingerprint associated with the audio recording; and

sending the audio fingerprint to the computing device.

5. A system of adding a user account to an unassociated device, the system comprising:

an unassociated device that is not associated with a user account;

an associated device that is associated with the user account;

a first computer-readable storage medium in communication with the unassociated device, wherein the first computer-readable storage medium comprises one or more first programming instructions that, when executed, cause the unassociated device to:

send a request to a computing device associated with a service provider of the user account, wherein the request comprises device information associated with the unassociated device,

receive a token,

broadcast an audio signal that comprises the received token,

receive one or more credentials associated with the user account from the computing device in response to the computing device receiving one or more authorization instructions from the associated device that is associated with the user account, and

use the received credentials to add the user account to the unassociated device; and

a second computer-readable storage medium in communication with the associated device, wherein the second computer-readable storage medium comprises one or more second programming instructions that, when executed, cause the associated device to:

detect, by a receiver of the associated device, the audio signal,

send to the computing device:

the token, and

one or more authorization instructions that instruct the computing device to send the one or more credentials to the unassociated device.

6. The system of claim 5 , wherein the one or more first programming instructions that, when executed, cause the unassociated device to receive one or more credentials comprise one or more programming instructions that, when executed, cause the unassociated device to receive one or more credentials via one or more of the following:

a short-range communication; and

an OAuth token.

7. The system of claim 5 , wherein the first computer-readable storage medium further comprises one or more first programming instructions that, when executed, cause the unassociated device to:

create an audio recording of an environment of the associated device;

generate an audio fingerprint associated with the audio recording; and

send the audio fingerprint to the computing device.
