Multi Factor Authentication
Basically would text (or other) each and every time you go to log in to specific sites or services. It's a good thing to use for super important stuff and accounts that can cost you money. It's a bit of a PITA when sites that just aren't that critical (that you use a lot) want to do it.
Chrome and Edge both will save passwords for you. If you utilize those aspects make SURE you have a very secure password and or log in method to devices that sync to it, particularly your phone.
As an aside from passwords, Windows 7 becomes less and less safe every day. Along with your passwords security, your OS being vulnerable is a wide open back door. I would consider moving up to 10 if your machine is capable. MS is being super lenient with upgrading license for same same upgrades 7 to 10, even still.
