Handle multiple originators for MessageBird phone auth about gotrue

[J0]

Hey @danbeech,

Thanks for taking the time to supply feedback. I confess I haven't used Bird so feel free to correct me the next few sentences if anything is off. My understanding is that an originator is a number so would the ideal behaviour be:

• Recipient has a US phone number -> Use US number to send the message
• Recipient has a number from elsewhere -> Use another number to send the message

Let me know

Hey @J0 thanks for getting back to me, I'm also not an expert on this so I'm kinda just repeating a conversation I had with Bird support. What you've said above is correct for the desired behaviour, the only difference is that I use text originators registered through Bird themselves rather than phone numbers. For Supabase you might register Supabase so that people know where the SMS has come from; so:

• US phone number -> Use the US number you've purchased & registered for 10DLC compliance - 10DLC docs from Bird
• Elsewhere -> Use the text originator/phone number provided as default in the Supabase dashboard settings

Unsure whether any other countries have similar regulations that would require a different originator, I haven't tried registering an originator for every country as they have to be done individually; so far I've registered 24, mostly EU states, and they're all working fine using the same text originator and one default value.
