Methods and Systems for connecting to online meetings are provided. In order to connect to an online meeting, coordinates for the meeting can be discoverable by an image or audio watermark overlaid onto content being shared by the online meeting. A person attending a physical meeting in which at least one attendee device or meeting facilitation device is connected to an online meeting can discover the coordinates for the online meeting by capturing and decoding an image or audio watermark overlaid on the content of the online meeting. The image or audio watermark may include a barcode superimposed on a content screen that can be captured and decoded by the person's computing device. A meetings application client on the computing device can be used to navigate to the coordinates discovered by the person's computing device to enable the person to join the meeting.
