@zalex108 Thanks for the information. Is "Sync" something that's enabled by default? If not, I'm not using "Sync" at all. I made a backup of my profile, saved only TWO passwords, that I entered manually, and neither password had been retained. So, I closed Opera and re-opened it and then the saved passwords were available. I also noticed Opera had been upgraded to version 64.0.3417.47. Weird.
I'll come up with 'plan B'. Thanks again for your help!
Peace...
