We should keep this kind of discussion to the user list 
There are two passwords in play, an admin password and a root password. Perhaps you can use one of them to bust-in and fix your login?
See http://docs.geoserver.org/stable/en/user/security/root.html for more details?

Dear Group, I recently changed the Geoserver password from default,. I feel i have changed the default password but when i ccheck in logs, it shows that the master password is changed. I remember the password and I still cant get any access to the page. Please help how do i get into my workspace? Is there any alternative apart from uninstalling and reinstalling? I cant do this at this time, because I have got my review and suddenly this happens. I have stored everything on my workspaces and if its the case that i have to reinstall, all the data i have worked previously will go to vain. Please let me know if there is any alternative. Thanks in advance. Very urgent!
