[Feature Request] Authentication (Optional)

[sebiweise]

Hi,
it would be great if there was a feature, that you could authenticate yourself in Spliit.
Authentication could be optional and if you authenticate you could link all your existing Groups to your account, define which user you are and then the correct id would be referenced in the corresponding groups.
This would help to reduce the amount of record in the Participant table and would also bring the feature kind of a "Sync" on every device.
I could login and would have all my groups directly available.
A simple and I think the best solution would be to use Auth.js (NextAuth).

In addition there could be a new ENV var to disable public group creation and enable/disable signup so you could just use your self hosted version for yourself.

I think I will start to develop on that feature.

Hi @sebiweise, we can collaborate if you need another helping hand.

group based authentication is enough ig, on a screen of who are you, we can ask who are you and enter passCode / security key for group, thats it. :)
