My bank does not like VOIP phone numbers for authentication text messages. Apparently there is a security issue with VOIP phone numbers. I found a thread " Anyone having issues with trying to use your phone number, for services requiring SMS validation?" that describes RW’s phone numbers as a subset of Bandwidth’s phone numbers. Bandwidth is a VOIP provider. From the thread, I gather the VOIP tag is FCC mandated and U.S. Bank will not accept that. The bank wants a RCD (Registered Cellular Device) phone number. Now that I see I am not likely to get RW to change the VOIP label, I have taken second tact.
I have asked U.S. Bank to develop an app that will run on RW and similar VOIP cell phones that will retrieve and display the one time codes for authentication independent of the SMS system. If U.S. Bank controls the app and it’s distribution, a hijacked phone number should not allow a hijacker to get the one-time code, which would a problem with SMS one time codes. I am waiting to see what the bank does.
I hate to beat this topic to death, but this issue with 2FA SMS texts not being sent to RW is an annoyance on an otherwise excellent phone service. Any thoughts?
