Please find a way to integrate all the individual log-ins for every journal that uses manuscript central into a single-user sign-on system. Elsevier went to this process for all journals that use their review system many years ago (i.e., My EES Hub) and it works great! I've noticed that a few journals have the ability to switch between partner sites once logged-in to the manuscript central portal for those journals, but it would really be helpful if there was a way to have a user log-in that would then give you the option to move freely between any/every journal that uses manuscript central for which you have an account as either an author or reviewer.
As an author and reviewer, I have more than 15 different journals that use manuscript central and every time I go to the individual site I have to enter a user ID and password specific to that site. I've attempted to make all the usernames and passwords the same, but for some reason sometimes I am not able to change the ID on certain accounts, nor am I able to keep track of every journal that uses MC to go into the system to change every site when I change one password. As a result I find myself constantly frustrated by the log-in system. Moreover, my web-browser and other password management software does not always recognize that each log-in page for individual journals is in fact different and continues to load passwords and user names from other journals, presumably either the one used first or the most recent.
I find it increasingly more challenging and often very frustrating that I end up with a different log-in and password for every journal that I interact with across the manuscript central platform.
