People always need to have 2FA active, but the most important aspect is that you don't click on links somewhere on the internet in order to visit a certain site. Always manually type your URL, which is a must.

Don't even bookmark anything. Type URL, check if it's correct, then proceed to the site. All this is common sense stuff.
