Anybody fed up with 2FA?

[Pat6671]

We live in an area with very poor mobile reception. When the weather is poor, the only reception we get is outside in the rain!

We use a password manager, with a 48bit passwords so feel pretty secure without 2FA. However it seems impossible to turn 2FA off and often means it can take us a day and a half before we can reply to guest (or prospective guests) messages.

Surely with decent passwords, 2FA is superfluous?

@Pat6671 2 factor authentication is not superfluous even with a complex password, because there are many ways for someone to get ahold of your password. Brute force is just one of many ways.
