In some examples, a session comprises an authentication session such that, when the session is copied, the user is logged into a network-based service within the second application with a same account as the user is already logged into with first application. ## Claims ### Claim 1 A method of downloading a first application on a first computing device and authenticating the first application to a network-based service using an already authenticated session of a second application on the network-based service executing on a second computing device, the method comprising: using a hardware processor of the first computing device: capturing a first image displayed by the second application on a display communicatively coupled to the second computing device; identifying a link to download the first application from the first image; downloading the first application from the link; responsive to downloading the first application, executing the first application, the first application: capturing a second image displayed by the second application; identifying a secret value from the second image; and establishing an authenticated session of the first application with the network-based service using the secret value. ### Claim 2 (depends on 1) The method of claim 1, further comprising, using a hardware processor of the second computing device: executing the second application, the second application: receiving a selection of a user interface option to download the first application; responsive to receiving the selection: displaying the first image; and displaying the second image. ### Claim 3 (depends on 2) The method of claim 2, wherein the first application identifies a session identifier from the first image and sends the session identifier to the network-based service, and wherein the second application displays the second image responsive to receiving a message from the network-based service. ### Claim 4 (depends on 3) The method of claim 3, wherein the second application replaces the first image with the second image. ### Claim 5 (depends on 3) The method of claim 3, further comprising, using a hardware processor of the network-based service: receiving a request from the second computing device for the first image; providing the first image to the second computing device; receiving a communication from the first computing device including the session identifier; and responsive to the communication from the first computing device including the session identifier, sending the second image to the second computing device. ### Claim 6 (depends on 5) The method of claim 5, further comprising, using the hardware processor of the network-based service: receiving the secret value from the first computing device; and authenticating the first computing device based upon the secret value. ### Claim 7 (depends on 1) The method of claim 1, wherein the second image is a barcode and wherein identifying the secret value from the second image comprises decoding the secret value from the barcode. ### Claim 8 A system for downloading a first application on a first computing device and authenticating the first application to a network-based service using an already authenticated session of a second application on the network-based service executing on a second computing device, the system comprising: a first computing device comprising: a hardware processor; a memory, the memory storing instructions, which when executed by the hardware processor, causes the first computing device to perform operations comprising: capturing a first image displayed by the second application on a display communicatively coupled to the second computing device; identifying a link to download the first application from the first image; downloading the first application from the link; responsive to downloading the first application, executing the first application, the first application: capturing a second image displayed by the second application; identifying a secret value from the second image; and establishing an authenticated session of the first application with the network-based service using the secret value. ### Claim 9 (depends on 8) The system of claim 8, further comprising the second computing device, comprising: a hardware processor; a memory, the memory storing instructions, which when executed by the hardware processor, causes the second computing device to perform operations comprising: executing the second application, the second application: receiving a selection of a user interface option to download the first application; responsive to receiving the selection: displaying the first image; and displaying the second image. ### Claim 10 (depends on 9) The system of claim 9, wherein the first application identifies a session identifier from the first image and sends the session identifier to the network-based service, and wherein the second application displays the second image responsive to receiving a message from the network-based service. ### Claim 11 (depends on 10) The system of claim 10, wherein the second application replaces the first image with the second image. ### Claim 12 (depends on 10) The system of claim 10, further comprising a third computing device of the network-based service, the third computing device of the network-based service comprising: a hardware processor; a memory, the memory storing instructions, which when executed by the hardware processor, causes the third computing device of the network-based service to perform operations comprising: receiving a request from the second computing device for the first image; providing the first image to the second computing device; receiving a communication from the first computing device including the session identifier; and responsive to the communication from the first computing device including the session identifier, sending the second image to the second computing device. ### Claim 13 (depends on 12) The system of claim 12, wherein the instructions of the third computing device, includes further instructions, which when executed, cause the network-based service to perform further operations comprising: receiving the secret value from the first computing device; and authenticating the first computing device based upon the secret value. ### Claim 14 (depends on 8) The system of claim 8, wherein the second image is a barcode and wherein the operations of identifying the secret value from the second image comprises decoding the secret value from the barcode. ### Claim 15 A machine-readable storage device, storing instructions for downloading a first application on a first computing device and authenticating the first application to a network-based service using an already authenticated session of a second application on the network-based service executing on a second computing device, the instructions, which when executed by a first computing device, cause the first computing device to perform operations comprising: capturing a first image displayed by the second application on a display communicatively coupled to the second computing device; identifying a link to download the first application from the first image; downloading the first application from the link; responsive to downloading the first application, executing the first application, the first application: capturing a second image displayed by the second application; identifying a secret value from the second image; and establishing an authenticated session of the first application with the network-based service using the secret value. ### Claim 16 (depends on 15) The machine-readable storage device of claim 15, wherein the instructions further comprise: executing the second application, the second application: receiving a selection of a user interface option to download the first application; responsive to receiving the selection: displaying the first image; and displaying the second image. ### Claim 17 (depends on 16) The machine-readable storage device of claim 16, wherein the first application identifies a session identifier from the first image and sends the session identifier to the network-based service, and wherein the second application displays the second image responsive to receiving a message from the network-based service. ### Claim 18 (depends on 17) The machine-readable storage device of claim 17, wherein the second application replaces the first image with the second image. ### Claim 19 (depends on 17) The machine-readable storage device of claim 17, wherein the operations further comprise: receiving a request from the second computing device for the first image;
