I want no part in 2FA. I believe in secure passwords and not being stupid. I hate safety culture. It's my business. If i mess up, it's on me. Ain't nobody's business to force 'extra' security on me, or to protect me from myself. I am not some 4 year old kid, I'm an adult. I actually know how to think for myself and have common sense. If I'm happy doing the same thing for 20 or so years, let me continue doing things that way until I DECIDE MYSELF that things should change.
Besides, when I was using it, I lost a few accounts when the phones died (and couldn't get the codes) or the phone number changed. It was just more annoying either way. Took ten times longer to login as a result. Back then, Smart TVs would log out of things such as Netflix or YouTube often, and having to deal with 2FA made the situation worse. Today, I just enter password and go.
I also don't trust password managers. If it's in the 'cloud' (Clouds are for rain!) it's able to be hacked or the data leaked. Just ask the T-Mobile customers.
I want life to be easy and comfortable, not endlessly frustrating. That's why I stay as far away from the 'future' as possible. Today's upgrades are massive downgrades. Just look at UI design today. Everything is made like it's the 80s again. Flat UI is not 'modern'. Modern = new, and flat UI is as dated today as DeskMate and Windows 1.x. The era when updates are actual progress and offered more features and improvements has been dead since 2015, or 2013 if you're an Apple fan. Nowadays feature removals, subscription software, and forced changes are the way. Every phone looks the same with few game changers out there (Z Flip is the only unique phone I could get) and there's even less competition than there should be. There was room for Meego, WebOS, Android, iOS, and even Windows Phone. There's no reason there should only be two OSs and two OEMS left. Heck, even Tizen is gone now. I don't want to revisit Wear OS. It was bad enough the first time!
Heck, in regards to 'modern' UI design, Meego on the Nokia N9 still holds up! I wish I knew what happened there. That was in 2011 for crying out loud!
