I'd be interested why you closed this issue. Isn't it true that at the moment, without authentication, one user could impersonate another one just by signing up with the same name?

I’m totally lost as to why I closed this issue, it’s still on my todo list for this. 🤔

How to fix Wrong user or password. problem ( with 100% correct alias and pass )? I am catching it only on svelte. Thx
