> I don’t understand why people bother replying to a question asking “how do you do x” with “I don’t do x.”

It might be easier to understand if you substitute "x" here with, say, "encrypting passwords with MD5". It illustrates better why someone might think giving "I don't do it" style of responses instead of directly answering the literal question that was asked.

Back to OP's specific case, maybe they keep creating accounts with SSO login only due to inertia and haven't really thought about reevaluating this habit. Not saying this is the case, since we don't know the specific reason OP is using SSO (e.g. if it's convenience, what makes SSO more convenient than the password manager? maybe they are following the recommendations from some random blog post that assumed a different threat model?).

So, alternative points of view might still be useful, if only as food for thought. Maybe a more fitting solution might come out of such discussions.
