Alasend seems very stable.

I have been using Roboform but I may have converted myself to a new tool. http://www.passwordmanagersso.com/

It has all of the feature as Roboform but the way Alasend works is much better.

• Support all the websites / icq / msn / skype / wow / warhammer / dark age of camelot / encrypted office file / encrypted winRAR
• DIY tool can acquire whatever you want to autolog as login task .  
• It has Main Interface instead of being set in the toolbar .
• Admin/Manage showing password for the users’ privilege .
