For a reasonable level of trust, I use the email address + password, like every website on earth. Seems to work well enough for Paypal, Amazon, et al. People do not change them much any more

That CAN'T be serious!! But sadly it is. HOLY IDIOCIES BATMAN! You have NO control over that.
Yahoo and every other free provider AFAIK reclaims email addresses after a certain period of nonuse (say, after the user DIES, rather unavoidable for every user eventually!).
So "JSmith2147" dies, his id is reassigned, and then you email his business info to someone else.
You're one of those consultants that clearly sells only to the pointy-haired manager types who rely solely on perceived reputation and don't have a real clue about the actual implementation details of what you're spouting.
