[Opera-Linux] how to see the password saved by the wand ?

[npomarede at corp.free.fr]

Hello,

I have a problem with the password I use on a site. I used the wand to 
remember login/password. I don't use a master password, so I can log into 
this site without problem, but the problem is that I forgot the password 
and I can't see it anymore :(  (I need it to log from another machine)

In preference/advanced, I can only see the login part of each remembered 
site by the wand, is there a way to see the associated password ? (firefox 
has such a mode, but I can't find the equivalent in opera).

How can I retrieve this lost password ?

Thanks
