I've had an Estonian e-Residency card. I had to pick it up at an Estonian police station and show my official government ID.

I don't see why a German university demanding the same for a comparable cryptographic certificate is bad.

It's not a "a comparable cryptographic certificate"

It's just a plaintext password

The student id card has a comparable certificate on it, as far as I understand it.
