Thank you yet again, @southpaw! I (and my wife) are both stuck with this issue, still. So I have requested the snail mail reset code, to go through a New Account type process with the SSA, again. The Two Factor Authentication (or 2FA, or MFA as the SSA likes to call it) was working for me and my RW phone for months - then stopped when I needed it again.
My continuing complaint to RW is that the supposed Help Article (which is the only thing which is shown when we search for Help in the RW app, or on the main RW website) still does not Help. The article really must clearly explain that anyone with issue needs to 1) Falsely tell the SSA website that their RW phone is no longer available (therefore should be deleted from the SSA account) and consequently 2) Request a snail mail reset code be sent, in 5 to 10 business days.
Not only is this not clear in the RW “Help” article, nothing on the SSA site makes this clear. So I (and my wife) went in circles for days, trying to find how to get an email authentication. Since this seems to be so complex in the RW and SSA service provider domain that six weeks have not been enough time to fix - the two week snail mail method is the best available.
Can someone at RW get the related RW “Help” article improved to actually help?
