7. The computer-implemented method of claim 1 , wherein the one or more access limitations comprise a limited access duration associated with the child access token, the request for the child access token comprising an indication of the limited access duration for the child access token.

8. A system comprising:

one or more processors;

at least one computer readable medium; and

computer readable instructions, stored on the at least one computer readable medium, that when executed by the one or more processors cause the system to:

receive, from a first electronic device associated with a user account of a synchronized content management system, an elevated access token associated with the user account, wherein the elevated access token is associated with one or more access limitations to content of the user account and enables the system to independently proxy authorization by requesting access tokens for other electronic devices without further input from the first electronic device;

send, to the synchronized content management system, a request for a child access token for a second electronic device and the elevated access token for generating the child access token based on the elevated access token, the request indicating authentication information regarding the user account for the second electronic device;

receive, from the synchronized content management system, the child access token in response to validating, by the synchronized content management system, the elevated access token; and

send the child access token to the second electronic device,

wherein the second electronic device is authenticated at the synchronized content management system based on the child access token,

wherein the second electronic device is granted, via the synchronized content management system, access to the content of the user account according to the one or more access limitations, and

wherein the elevated access token is configured to propagate to the child access token any access limitations added to the elevated access token after the child access token is generated and any access privileges revoked for the elevated access token after the child access token is generated.

9. The system of claim 8 , wherein the system is a router.

10. The system of claim 8 , wherein the computer readable instructions, when executed by the one or more processors, cause the system to send, to the first electronic device, a system identifier associated with the system.

11. The system of claim 8 , wherein the child access token is effective to grant a bearer of the child access token access to a subset of the user account that is based on the one or more access limitations.

12. The system of claim 11 , wherein the one or more access limitations comprise at least one of read-only access to the user account or a limited duration of access to the user account.

13. A non-transitory computer-readable medium storing computer executable instructions that, when executed by one or more processors, cause a computing device to:

receive, from a first electronic device, a request to send an elevated access token, associated with a user account of a synchronized content management system, to a network device;

generate, via the synchronized content management system, the elevated access token for the network device, wherein the elevated access token is associated with one or more access limitations to content of the user account and enables the network device to independently proxy authorization by requesting access tokens for other electronic devices without further input from the first electronic device;
