This is the issue with companies forcing 2FA on people. I don't see why it's so controversial that people should be able to make their own security decisions on their own accounts. Yes, I know 2FA is more secure, but sometimes, I just don't care that much.
I get around their phone number prompts by hitting the back button and trying the login again. Sometimes I get an option to add it later so I click that. So far, I have had no problems accessing my google accounts with nothing more than a fake.name_@_gmail.com identity. The names really are pretty close to that. LOL I always login in a new window with no other tabs open and delete cookies as I close the window (Firefox). It's like a brand new world every time.
