And another question. I want to solve the problem of having our users only sign in once for all services. e.g user visits :3000 first. signs in, does some stuff, and then navigates to service B which is protected too under :4000 and the user should be automatically signed in. (i don't have DNS available therefore need to use ips here). is this possible with supertokens?

hey @Kuirak if the IPs are different, then you will need to implement supertokens as an oauth provider on a common login portal. We are not yet an oauth provider, but you can implement the implicit oauth flow (search discord for "implicit flow") If the IPs are the same, but the port is different, the same session can be used across the different domains and should not require any change (assuming that the api these websites are querying is also on the same IP address)
