For example, a method may include determining whether a media playback device is being controlled by a user. In response to determining that the media playback device is not being controlled by the user, the method may further include: causing display of a pictograph that includes an encrypted payload with information for wirelessly connecting to the media playback device and is configured to be scanned by a client device; determining whether a request from the client device to wirelessly connect to the media playback device is a valid request; in response to the request being valid, wirelessly connecting the client device to the media playback device via a soft access point; and receiving, at the media playback device, information for reconfiguring the media playback device. ## Claims ### Claim 1 A computer-implemented method comprising: causing, by at least one processor, display of a pictograph via a media playback device, wherein the pictograph comprises an encrypted payload comprising: information for connecting to the media playback device, and a cryptographic certificate to identify the media playback device by a server; receiving a request from a client device to connect to the media playback device, wherein the request includes a server-decrypted version of the information for connecting to the media playback device; determining that the request is valid; in response to determining that the request is valid, connecting the client device to the media playback device based on the server-decrypted version of the information; and receiving reconfiguration information for reconfiguring the media playback device. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the reconfiguration information comprises wireless settings. ### Claim 3 (depends on 1) The computer-implemented method of claim 1, wherein causing the display of the pictograph is performed in response to determining that the media playback device completed an initial setup process. ### Claim 4 (depends on 1) The computer-implemented method of claim 1, wherein the encrypted payload further comprises account information of a user of the media playback device. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein the encrypted payload further comprises a network name and a passphrase. ### Claim 6 (depends on 1) The computer-implemented method of claim 1, wherein the cryptographic certificate comprises a public key associated with the media playback device. ### Claim 7 (depends on 1) The computer-implemented method of claim 1, wherein the pictograph comprises a quick response (QR) code. ### Claim 8 A system, comprising: one or more memories; and at least one processor each coupled to at least one of the one or more memories and configured to perform operations comprising: causing display of a pictograph via a media playback device, wherein the pictograph comprises an encrypted payload comprising: information for connecting to the media playback device, and a cryptographic certificate to identify the media playback device by a server; receiving a request from a client device to connect to the media playback device, wherein the request includes a server-decrypted version of the information for connecting to the media playback device; determining that the request is valid; in response to determining that the request is valid, connecting the client device to the media playback device based on the server-decrypted version of the information; and receiving reconfiguration information for reconfiguring the media playback device. ### Claim 9 (depends on 8) The system of claim 8, wherein the reconfiguration information comprises wireless settings. ### Claim 10 (depends on 8) The system of claim 8, wherein causing the display of the pictograph is performed in response to determining that the media playback device completed an initial setup process. ### Claim 11 (depends on 8) The system of claim 8, wherein the encrypted payload further comprises account information of a user of the media playback device. ### Claim 12 (depends on 8) The system of claim 8, wherein the encrypted payload further comprises a network name and a passphrase. ### Claim 13 (depends on 8) The system of claim 8, wherein the cryptographic certificate comprises a public key associated with the media playback device. ### Claim 14 (depends on 8) The system of claim 8, wherein the pictograph comprises a quick response (QR) code. ### Claim 15 A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising: causing display of a pictograph via a media playback device, wherein the pictograph comprises an encrypted payload comprising: information for connecting to the media playback device, and a cryptographic certificate to identify the media playback device by a server; receiving a request from a client device to connect to the media playback device, wherein the request includes a server-decrypted version of the information for connecting to the media playback device; determining that the request is valid; in response to determining that the request is valid, connecting the client device to the media playback device based on the server-decrypted version of the information; and receiving reconfiguration information for reconfiguring the media playback device. ### Claim 16 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the reconfiguration information comprises wireless settings. ### Claim 17 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein causing the display of the pictograph is performed in response to determining that the media playback device completed an initial setup process. ### Claim 18 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the encrypted payload further comprises account information of a user of the media playback device. ### Claim 19 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the encrypted payload further comprises a network name and a passphrase. ### Claim 20 (depends on 15) The non-transitory computer-readable medium of claim 15, wherein the cryptographic certificate comprises a public key associated with the media playback device.
