I'd like to submit a feature request.
In some cases, it would be a great to be able to deploy a CrypPad instance, but without letting anyone able to create an account. I didn't found any CrypPad configuration which could let me do this.
As reference, it's possible to disable to the register feature on Gitlab when it deployed on a personal instance. It would be nice to be able to do the same.
We could let admins create accounts with default passwords that would have to be changed on first login.
