Hi Jwarren,
Thank you for the feedback, as we also use Method users here, so I do agree with what you are requesting. I can definitely make a request to add this option to the pop-up sign-in Window. However, I believe there is currently a link on this Timeout pop-up screen to go back to the main login page, where you can use your OpenID from. This screen is likely going to change when we release the newer version of Method, so I can't say for sure that this will be added down the line to the current version you are using, I will add back to this thread if I get any further information.
