1. Enable Sign-in with Phone Number for your Firebase project
To enable your users to sign-in by SMS, you must first enable Sign-in with Phone Number method for your Firebase project by following these steps:
- In the Firebase console, open the Authentication section.
- On the Sign-in Method page, enable the Phone Number sign-in method.
Firebase's phone number sign-in request quota is high enough that most apps won't be affected. However, if you need to sign in a very high volume of users with phone authentication, you might need to upgrade your pricing plan. See the pricing page.
