Question: I was testing my login/sign up feature and for some reason I can't understand Firebase now is blocking all requests from my device.

I've waited one day to try again, but I still have the same problem.

What should I do to have access to my database again?

Answer: 
If you use **Phone Authentication**, Here is what to do:

1. Go to **Firebase Console**
2. **Authentication** ==> Sign-in-method
3. Go to **"Phone"** and pop-up will show
4. Add your phone number at "**Phone Numbers for testing**" along with a *verification code* from your choice.

And it works now :)
If you are doing tests a better way to go about it is to add the phone number as a test number Authentication > Sign in method > Phone. Then add the test number + the verification code you'll use
