Consider this a feature request :)

Got it :)

Alternatively, once you have registered all the users you need, you can then disable registration by re-deploying museum after commenting out the following line -

ente/server/pkg/controller/user/userauth.go

Line 324 in f2057cb

userID, _, err = c.createUser(email, source)

This will stop new accounts from being created.

Would you consider accepting a pull request that makes the registration of a user configurable via the yaml file/env variable, to disable registration without needing to edit the code?

Okay. Let us add "internal.disable-registration". Thank you.

It might be a good idea to add a flag/envvar for the webui aswell to disable the link for registration when set. Something similar like the existing overrides for the endpoint

Not sure about that. Web is not the only client.

Let's keep the scope small and only deal with the museum bit for now.
