I do sometimes give my passwords out to things, usually all for valid reasons

like, I'll give my password to the computer engineer to fix a problem with my PC, and once when my computer was down, I gave someone my amazon password so they could order something for me

but with that said, I always change the passwords afterwards so that they can't use it at their will

I also think it's really impoertant to give out my passwords to someone I trust for when I die, so they can come on and let people know. I wouldn't want to just vanish from my websites without anyone knowing what had happened to me
