You miss the crux of it: the second time onward the clearing houses uses email to authenticate the previously-SMS-verified account.
- supriyo-biswas 3y agoThe clearinghouse may not have the user’s most recent email address, which is common amongst non-tech people. My mom and aunts have lost many email addresses this way and forcing them to use an older email would cause many issues.
- explaininjs 3y agoThe app has to ask for email/phone to begin with (see step 1), if the email doesn't match then phone would be used as fallback, or potentially as a "Didn't Receive Code?" gesture.
