Safari Issues since OS update to Mojave

I recently updated my 2017 MacBook Pro to OS Mojave and I am very tempted to restore to the previous OS. The issues lie in Safari for some reason, when visiting websites and creating accounts, I no longer have the option to save my username and password. Also, every single time I visit a website, I am asked to verify by either selecting "Trust this page" (it even does it EVERY time I visit this page) or I have to verify with a passcode, text or email and this includes pages I have bookmarked in my favorites, as well as sites I have visited before. I do not clear the cookies nor empty the cache, but the Mac is acting like I do. I only use my Mac on my home network. I did not have these annoying issues on OS Sierra. If anyone can offer some assistance that would be greatly appreciated. Thank You!
