Looks like we can’t update session variables - [Nakama: Sessions | Heroic Labs Documentation](https://heroiclabs.com/docs/nakama/concepts/session/#setting-with-server)

How we can force user to re-authenticate?

I found this if you’re using the C# SDK on the client side.

`await client.SessionLogoutAsync(session);`

For some reason the forum is blocking me from posting a link to their own documentation. If you want to find it, its on the `Client Libraries > Unity` page under the `Authentication > Ending Sessions` section.

Looks like its under the Session section in the server side function reference. [Here’s](https://heroiclabs.com/docs/nakama/server-framework/function-reference/typescript/#Sessions) the link to the Typescript functions but I’m sure they have them for Lua and Go as well if you’d prefer those.

I’ve found no in-memory datastore for Typescript, unfortunately. Global variables are freezes. This is impossible via typescript?
