Yeah I don’t really care about I’d but the problem is spam. Maybe phone text authentication is an alternative, idk how much that costs to implement though.
About 5c per msg, a bit lower for some countries, a bit higher for others.
Is there no service out there where you can just buy a number and use it for text validation
You could build one yourself by grabbing some hardware that includes a modem and grabbing a sim card from a local provider with "unlimited" text messages.
