Just got a huge bill of 2900 USD on Firebase for the month of April. Realized that it happened because of SMS traffic fraud where our Firebase Auth was called thousands of times every day.

I thought AppCheck was supposed to prevent this kind of attack. It's a friggin SMS hack again. We've just gotta get rid of whatever SMS authentication we have. Just doesn't make sense and my heart can't take random $700 charges every now and again.
