Pidgin stores you passwords in plain text in ~/.purple/accounts.xml.Someone can easily boot into recovery mode while you are away and find your passwords in plain text.
Download the patch from here into the same directory and do the following
tar xf master-password.patch.tar
patch -p 1 < master-password.patch You should be ready to configure, make, and install as normal. ./configure make sudo make install When you launch pidgin, you will see a new tab in the preferences called "security". You can set a master password there. The link above has screenshots. After configuring, you should notice that the accounts.xml file now has gibberish where there once were passwords. To remove pidgin, run the following from the directory in which you built pidgin make uninstall This will work for pidgin 2.1.0,2.1.1 versions.
