That SMS gateway should be a more or less a dumb pipe that transmits whatever it is sent by the provider. It so happens that now the pipe is closer to the user but the source stays the same. The SMS gateway and telecommunications companies can certainly surveil or modify the content (the latter wouldn't be useful for 2FA), but it should not generate the codes. -- *Collin David Anderson* averysmallbird.com | @cda | Washington, D.C.
