Customizable SMS Verification Messages for Firebase Authentication
Currently, SMS verification messages in Firebase Authentication include fixed text elements that cannot be customized. For Netherlands numbers, the message includes "Firebase App" text and a link, while for non-EU numbers, this text is omitted but still includes a link. Because some developers need to align SMS messages with their brand voice, remove links, or meet specific regulatory requirements in different regions, this lack of customization limits the flexibility and usability of Firebase Authentication.
Implementing a feature that allows developers to customize the text content of SMS verification messages would greatly enhance the service. This should include:
- Ability to use custom text in the SMS message.
- Option to remove any links from the message.
- Flexibility to set different message formats for different regions if needed.
Allowing developers to customize SMS verification messages (similar to customizing email templates) would make Firebase Authentication much more versatile and adaptable to various use cases and regional requirements. This would improve user experience with clearer, brand-aligned messages and potentially increase successful verifications due to clearer messaging.

This is crucial. An 'unknown sender/text message' can cause confusion for the end user.
