[WikiEN-l] How to disable unified login?

[nsk]

I unified my accounts, but unfortunately the way unified login is
implemented has some disadvantages which are showstoppers for me,
therefore I would like to disable my account unification and return to
the previous state.  Is this possible?

Alternatively, is there any way to keep my accounts unified but get rid
of this "successful login" message? (yes this is the showstopper)

Thanks,
