A server, primary client device, and secondary device may be provided. The server may be configured to receive a login request sent by a secondary client device, the login request including a secondary account identifier and an encoded image, the secondary account identifier associated with a secondary account. The server may decode the encoded image to identify a primary account identifier and an expiration time indicator encoded in the encoded image. The server may determine that the secondary account is linked with a primary account. The server may compare the expiration time indicator with the request time to determine that the encoded image has not expired. The server may authorize privileged communication with the secondary client device in response to the secondary account being linked with the primary account and determination that the encoded image has not expired.
