Adding test phone number in firebase phone authentication

Question

How to add test phone numbers for firebase phone auth, to skip otp screen or entering a predefined otp.

Answer 1

The solution to this issue involves removing your phone number from the Authentication > Users tab. After that, Firebase will allow your number in the test list.

1. Go to the Firebase console and open your project.
2. Navigate to the "Authentication" section.
3. Click on the "Users" tab.
4. Search for your phone number in the list of users.
5. Once you find your number, select it and click on the "Delete" or "Remove" option.
6. Confirm the deletion when prompted.

After removing your phone number from the users list, Firebase will treat it as a new number and allow it in the test list for phone authentication. You can then proceed with testing your phone number in Firebase without any issues.

Remember to make sure you have the necessary dependencies and configurations set up correctly in your project for Firebase phone authentication to work smoothly.
