Hey @polite-finland-39423
Thanks for the details, that helps a lot!
I think Kratos would be your ideal solution to build such a “central session/user management” system.
It has a ton of features geared just towards what you are looking for!
It integrates nicely with Hydra (self-hosted needs some config, Ory Network out of the box)
There are probably details I am missing now, but as far as I see it you have two options:
• build custom session management with Hydra yourself
• use a solution developed by Ory exactly for this, that is maintained and used by hundreds of companies.
Of course it could be very easy to develop what you are looking for, but in that case you still have to maintain it indefinitely, not ideal IMO.
