2FA is great. It's the best tool there is against impersonation and account takeovers.

But it's only great PROVIDED

It's a real, proper second factor like a hardware token or - less great but okay - a "secure" cellphone app. When it's a totally insecure factor like SMS, 1FA is preferable.
It's not such a PITA that you hate using it.
When it's a proprietary app from one of the big data sonsabitches, it's also an app to spy on you and your activities.
