in response to detecting the request to log the user out of the online account, logging the user out of the online account on both the first computing device and the third computing device.

10. The method of claim 1 , wherein logging the user out of the online account comprises preventing an unauthorized entity from accessing sensitive data stored within the online account.

11. A system for logging users out of online accounts, the system comprising:

a request module, stored in memory, that receives, from a first computing device of a user, a request from the user to log into an online account that:

enables the user to perform at least one online task; and

is hosted by an online platform;

an establishing module, stored in memory, that establishes, between the online platform and a second computing device of the user, a network session that both:

verifies the identity of the user to the online platform by providing, to the online platform, authentication credentials associated with the user; and

at least partially disrupts the functionality of the second computing device while the user is logged into the online account via the first computing device such that the user is motivated to log out of the online account after performing the online task;

an authentication module, stored in memory, that logs the user into the online account via the first computing device in response to the network session being established between the online platform and the second computing device;

wherein the request module further detects a request from the user to log out of the online account;

a termination module, stored in memory, that in response to the request to log out of the online account:

restores full functionality of the second computing device by terminating the network session between the online platform and the second computing device; and

logs the user out of the online account; and

at least one hardware processor that is configured to execute the request module, the establishing module, the authentication module, and the termination module.

12. The system of claim 11 , wherein the establishing module establishes the network session between the online platform and the second computing device of the user by establishing a phone call between the online platform and the second computing device.

13. The system of claim 11 , wherein the establishing module establishes the network session between the online platform and the second computing device of the user by providing, via a network connection between the online platform and the second computing device, a software token that runs on the second computing device.

14. The system of claim 11 , wherein the network session provides the authentication credentials associated with the user to the online platform by providing the user with a one-time password that the user enters to the online platform via the first computing device.

15. The system of claim 11 , wherein the network session disrupts the functionality of the second computing device by preventing, while the network session is established via an application running in a foreground of the second computing device, the user from accessing at least one additional application installed on the second computing device.

16. The system of claim 11 , wherein the authentication module further determines that the user has entered authenticated login credentials into the online platform via the first computing device prior to logging the user into the online account.

17. The system of claim 11 , wherein:

the request module detects the request from the user to log out of the online account by determining that the user has initiated a logout process on the first computing device; and

the termination module terminates the network session between the online platform and the second computing device by automatically terminating the network session without input from the user on the second computing device.
