Interesting. I have felt the need for this before. Do you also support authenticator app codes? I believe authenticator apps are recommended relative to SMS.
It's different for two reasons:
- As @detaro mentioned, it's a fully managed solution where you don't have to set it up, or more importantly, maintain it - it's all done for you.
- Twilio numbers do not receive SMS messages from short code numbers, which are usually the ones sending 2FA messages.
If you think in terms of how much your time is worth:
- How much of would it cost you to forward a 2FA message to a team mate?
- Maybe two messages, if the first one expired by the time they saw it?
There's the ancillary cost of the frustration if something goes wrong, as well as dropping whatever you were doing to do this menial task.
This has been fully automated and managed with SMS to Slack.
