Establishing a dynamic connection across systems is provided. The method comprises receiving user login credentials from a user from a first device and authenticating the user login credentials in connection with a user account. A session is created in response to successful authorization of the user login credentials, wherein the session comprises a session state that tracks user activity and any changes to a user account during the session, and the first device is bound to the session state and saved as a known device. Upon detecting activity of the user on a second device, a quick response code is created for the user. When the user inputs the quick response code from the second device, the second device is bound to the session state and logged into the session with the session state preserved.
