Did you upgraded to Joomla 1.0.13 and now you can't login?
Do you are an early adopter and you upgraded to Joomla 1.0.13? And you have Community Builder, VirtueMart or SMF Bridge...and you cant' login right now, and/or your users are complaining about the same problem. We're sorry for you... Do you have a backup? Then is simple, restore the Joomla 1.0.12 files, overwriting the actual files with those from the official distribution package and restore the jos_users or similar (or at least the passwords column from that).
Do you have backup, don't you? No??? Ouch... humm, then the job is a bit harder, but can be done!

Here is one way you can do this!
