I personally think it's best to keep 2FA keys out of password managers.
The whole point of 2FA is to have a seconds factor to authenticate you.
If someone gets access to your password vault with your 2FA keys, they have access to all of your accounts - 2FA protected it not. If you keep the keys in another app, they cannot access your accounts nearly as easily.
Ok but to balance it: it forces you to confront your own on the topic as well.
That would force you to selectively use it since often times reality is somewhere between our personal view of it and other opposing views.
Chose the wrong situation and you'll both be crying in the corner with shatter worlds. Chose the ones where the people are truly disconnected from reality and perhaps you'll change their lives - hopefully for the better.
