-- **Edit 220504:** Starting from being logged out of every one of EasyEDA Std, EasyEDA Pro, LCSC, JLCPCB or OSHWLab, when first logging in to any one of EasyEDA Std, EasyEDA Pro, LCSC, JLCPCB or OSHWLab and then opening, refreshing or clicking Login on any of the other sites, does log the user in to all of the 4 remaining sites. So, for example, if logged out of all sites, logging in to EasyEDA Std will also log the user in to EasyEDA Pro, LCSC, JLCPCB and OSHWLab. Similarly, if logged out of all sites, logging in to LCSC will also log the user in to EasyEDA Std, EasyEDA Pro, LCSC, JLCPCB and OSHWLab. Logging out of any one of EasyEDA Std, EasyEDA Pro, LCSC, JLCPCB or OSHWLab then also logs the user out of all 3 of  LCSC, JLCPCB or OSHWLab but not out of EasyEDA Std or EasyEDA Pro. So, for example, after a first login to all sites as described above, logging out of EasyEDA Std will also log the user out of LCSC, JLCPCB and OSHWLab but not out of EasyEDA Pro. Similarly, after a first login to all sites as described above, logging out of any one of EasyEDA Pro will also log the user out of LCSC, JLCPCB and OSHWLab but not out of EasyEDA Std. Similarly, after a first login to all sites as described above, logging out of JLCPCB will also log the user out of LCSC and OSHWLab but not out of EasyEDA Std or out of EasyEDA Pro. This is fine as long as the user stays logged in to all sites but the moment either the user logs out an any site or the login session expires for any site then they find that they are logged out of LCSC, JLCPCB and OSHWLab. Unless the user logs out any remaining site that they are still logged in to (EasyEDA Std, EasyEDA Pro or both) they they have to log back into each site in turn. This is confusing and frustrating because the user has no notification that this has happened and no way to discover why it has happened. The frustration is made greater because the sites do not consistently keep people logged in. They appear - at least to the user - to log them out after a random time for a randomly chosen site. The add the fact that this applies to all the sites for each platform that a user may be logged in from, it turns into login hell! For example, I am logged in from a phone, a Windows PC and a Linux laptop. On a bad day that means I may have to log in to between 9 and 14 different sites because I am still logged in to to one of EasyEDA Std or EasyEDA Pro. The behaviour and consistency of the "One Account: Sign in to all your tools with just one account" needs to be clarified and improved. Either remove the auto session expiry or log the user out of every site so that they always start from a clean "not logged in anywhere" state would be a good start. Warning users that their sesson has expired and so they are logged out would also be helpful. ## **End of edit 220504.** What is going on with logging in to EasyEDA Std, LCSC, JLCPCB and OSHWLab? "Sign in to all your tools with just one account." is just not working. Not only do I have to keep logging in every day or so on each platform that I use EasyEDA on, I am now having to log in separately to each of EasyEDA, LCSC, JLCPCB and OSHWLab as well. Here I am: clearly logged into EasyEDA Std (I am posting this from the same login session):  yet when I click User Center, I am asked to log in:  Notice the left hand panel: "One Account Sign in to all your tools with just one account. [EasyEDA](https://easyeda.com/)[LCSC](https://lcsc.com/)[JLCPCB](https://jlcpcb.com/)" Yet when I click on any of those tools or the Services in the bottom of the EasyEDA home page:  I am asked to log in to:  or:  or:  <br> <br> <br> <br>
