Or if you're setting up a SaaS application where some of your customers will want integration with their own SSO. We don't have developer time to spare implementing that sort of thing but Auth0 lets us do it as one of its built-in integrations.
It lets us offer SSO with whatever Auth0 supports as a freebie add-on, instead of "well, we could work with your platform but it's gonna cost you."
I don't see how it's a trap, except that we have to pay auth0 a monthly fee to handle our authentications instead of having some number of hours a month spent maintaining and securing our customers' logins and integrations.
