Hi there!
I have found a problem regarding the built-in auth features when using email addresses containing german Umlaute (ä, ö and ü). The login service always responds with validation failed.
As i am using a custom registration service I dont know, if the register method already would fail with these accents. I dont if its worth looking into it as they are really rare. Just wanted to drop it 🙂

Solution

We are using a pretty specific regex to validate emails, we should probably simplify it to accept email addresses with umlauts:
