Using this link to set this up: FirebaseRecaptcha - Expo Documentation

I’ve run:

$ expo install expo-firebase-recaptcha
$ expo install react-native-webview

  1. I copied the code that is put in the example (I have changed nothing).
  2. I mount this example component into one of my screens.
  3. I see the phone verification inputs and I enter my phone number.
  4. The recaptcha web view opens in a browser
  5. I click the checkbox to verify I’m not a robot.
  6. Some pictures appear, I select accordingly.
  7. The web browser closes back into my app.
  8. I see a red error message “Error: Invalid format.”

Something is either wrong with my setup (I have firebase running perfectly with email auth) or something is wrong with the Recaptcha. :man_shrugging:

Any help?

This demo doesn’t work on my phone, I get the same error as described above. My " OAuth redirect domains" is set to my app.json firebase’s authDomain, which I obtained when setting up my Firebase account. These are the same properties used when I initialize firebase within my app. And I use those same properties in the above Snack, which results in the same “Error: Invalid format” error.

@ijzerenhein are you experiencing the same issue I’m having with the Snack?

@adriaanbalt I believe invalid format means that the phone number that you entered is not recognised as a valid phone number. You can try by adding a test phone number in the firebase console Authentication -> Sign in method -> Phone

Turns out the phone numbers has to include the country code ie: +1 for the USA
