In my app, I'm using 4 digit OTP verification service. Now I'm trying to add Firebase phone number authentication method as my fallback method. Firebase OTP gives me 6 digits but I do not want to change my existing UI. How can I customize this?

You can use Firebase Authentication to sign in a user by sending an SMS message to the user's phone. The user signs in using a one-time code contained in the SMS message.
From the use of firebase OTP verification using a phone number is FREE.
Don't forget to go in Firebase Project Settings > App check > and Register firebase project in SafetyNet and Play Integrity register with default time token 1 hour and u will remove reCaptcha from phone auth OTP! That's awesome.

There is currently no way to change the length of the verification code that Firebase uses. I recommend that you file a feature request.
If you don't want to depend on whether/when Firebase may add this, you can implement your own identity provider, where you have full control over its operation, including the password strength requirements.
