I don’t have an obsession with security, it’s just so easy and cheap that I don’t get why you wouldn’t do it (the people with an obsession with security probably don’t even trust 1Password to sync that encrypted file anyways)
My mom, who is as far removed from tech as you can get, understands why not sharing passwords might be a good idea when one can get hacked and set of a domino effect.
And your comparison is a straw man, the real comparison is trying to remember 50 random passwords to using a password manager because there is a sea of research showing that good passwords should be truly high entropy and random.
Using a password manager doesn’t stop you from using 2fa like your comparison is worded to imply.
