I been just allowing my browser to remember and then sync it. I was surprised that win10 that I just got was so easy to set up. Wifi/ethernet easy. Certainly blows my 9yr old win7 away!!
I recently got a new laptop too. I was dreading Windows 10, but it has really been a easy transition. Some thing work different, but once I thought it out, I had no problems.
I kept an index card of passwords but it got out of hand so I now have a file on my laptop. I keep a printout in the safe.
