Many services offer 2fa authentication via SMS these days. It would be great if Textra could recognise these senders and the part of the message that contains the code. Then either copy the code to clipboard automatically or offer a button for the user to do it, so they can just paste it into the app that is waiting for it.

This might not be practical for every obscure service that uses it, but the big ones like Facebook or PayPal could still be really handy.
