But I'm supposed to be able to backup my Windows account security credentials (a decryption key or something of the sort) and import it on another machine to use it, right?
Is there some step-by-step guide to do this?

I recently left behind Opera 12 and am now using Opera 20. Previously, all I had to do was backup my wand.dat file; however, there is no such file for Opera 20, that I can tell. So, I am still trying to figure out how to backup/export my saved users/password. Is it even possible to do so?

Thank you.

Yes, I know my Opera 12 is there and unchanged and I can see that some of the data was imported into Opera 20. However, my passwords have not.
Perhaps I should mention that at the time of installation, my passwords were still encrypted with the "master password" option in Opera 12. Could this have made a difference and be the reason why my passwords haven't been imported?

I have hesitated to switch to post-Opera 12, but here I am. I am trying to transfer my saved password from Opera 12 to Opera 20 and copying the wand.dat file, after decrypting it, did not do the trick.

Is it even possible to do such a thing and, if yes, how?

Thanks.
