There are various possibilities when passwords can be stored in eclipse and subversion. The keyring file is stored in the eclipse installation, which I used with a sub-loan in <root>/eclipse/configuration/org.eclipse.core.runtime/.keyring . You should at least see if it exists there. The location of this file can be overridden by command line options, but you know. For more information, see the article βHow to Change the Password of the Eclipse SVN Pluginβ .
For another option, you can check:
- Go to
Windows > Preferences Settings Windows > Preferences . - Select
General > Security > Secure Storage . - Go to the
Contents tab and open the SVN entry there.

You should now see the local cache of SVN-related things that SVN can use to answer the password question for the server. Delete the entries that are cached for the location you want to log in as another user. Make sure your subversion directory is also empty:
- Windows XP:
C:\Documents and Settings\{User}\Application Data\Subversion - Windows 7:
C:\Users\{User}\AppData\Roaming\Subversion\
And delete the .keyring file if you find it.
