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: 
I managed to get this working straight away by resetting the users password.

Steps are as follows:

1. Go into your admin console, Authentication, Users
2. Locate the user
3. Click on the menu dots in the far right hand column
4. Choose reset password, then click ok
5. Follow the steps in the email when it comes through
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
