Hey Product Hunt! I'm the maker of loginos. Sign-in gets painful the moment a product lives on more than one domain: brand sites, country sites, or customers who bring their own domain. Every domain wants its own login, and people end up with five accounts and five passwords. loginos gives all your domains one user pool: • Sign up once, signed in everywhere • Returning users tap "Continue as" right on your page in Chrome and Edge, no redirect (a small popup in other browsers) • Passkeys with Face ID or fingerprint, passwords as a fallback • Roles and permissions arrive in every token • Already have users? They link their account once, no migration • New domains can add themselves: when someone signs in on a domain you haven't added, loginos asks your server and adds it only if you say yes It's standard OpenID Connect: two routes on your server, or paste one ready-made prompt into Claude Code or Cursor and let it do the integration. It's free to start, no card needed. I'd love your feedback, especially on the docs and the first setup: where did you get stuck?
