Answer 1

Neither the email verification template nor the SMS verification template can be modified. You can select the language from the Firebase console, however this is a per project setting and you can't modify the templates.

We understand that changing the template would allow you to tweak the user-experience of your app, but we don't allow this to prevent abuse of the service.

Update 1 year later, still a no go, but I received this back from support

The Firebase SMS Authentication message content will depend on the platform you are requesting that message from. Here is a list of the possible variations you may get:

• iOS and Android - The SMS messages draw the app's name from the App Store / Play Store. One an app is published, the correct name
  should start appearing. There may be a small delay (a week or two at
  most).
• Web - It will always use the domain that the SMS is requested from. To modify it, you can setup a custom domain.
• iOS (using Recaptcha) - Phone authentication on iOS will show the project's url instead of the app's name in the verification SMS when using the reCAPTCHA flow. This is expected behavior. The reCAPTCHA flow was added for cases where an APNS token is not available (including on real devices). If APNS is not correctly configured, a real device will default to the reCAPTCHA flow.

Unfortunately, neither the email verification template nor the SMS verification template can be modified. You can select the language from the Firebase Console, however this is a per project setting and you can't modify the templates.

We understand that changing the template would allow you to tweak the user-experience of your app, but we don't allow this to prevent abuse of the service. I hope this clears your consults about this topic. If you happen to have any more questions, please, do not hesitate to write back!

Answer 3

Meanwhile you cannot change the content of the message, you can change the app's URL mentioned in the SMS.

1. Go to Authentication > Sign-in Method > Authorized domains and add your own domain website.tld

2. Now edit the Firebase config object (in your source code) and update the authDomain key to the domain you linked earlier.

Send a new test message, you're good to go.

Answer 4

As per Firebase Support the %APP_NAME% should be shown in your firebase settings wherein the %APP_NAME% is called after Public-facing name in public settings.

EDIT:

I checked first where is the location of "localhost" and wherein i found on "Authentication>Sign-in method" then under 'authorized domain' you will find "localhost" in order to change the localhost you need to add a new domain.

Note: be careful on deleting localhost to your authorized domain. It will take time to function OTP request.

Answer 5

This one helps; Go to Authentication > Sign-in Method > Authorized domains and add your own domain website.tld

Now edit the Firebase config object (in your source code) and update the authDomain key to the domain you linked earlier.
