Ask HN: Anyone else constantly forget which SSO service they signed up with?
10 by lordofmoria | 7 comments on Hacker News.
Curious if anyone else finds it increasingly difficult to play "SSO roulette" when logging into the long tail of infrequently-used services: did I use GitHub? Facebook? G Suite? Twitter? Or the secondary problem: "if I used Google SSO, which of my gmail accounts did I use?" I definitely have my own heuristics (g suite for everything possible, github for "technical" sites, facebook as a throwaway, etc), but I've found myself increasingly "getting it wrong." Not to mention this is worsened by the fact that some sites automatically create a new account for you if you log in with a non-existing account: this means you often end up creating a NEW account, further screwing yourself over. Anyone have any good hacks to solve this? I've started resorting to storing a blank 1Password entry even for sites I SSO with, simply stating the SSO account and email I used.
