No, it's a matter of choosing what risk I'm going to take.
As far as I'm aware, there is no way to retrieve a password from an OBi ATA. Even if I'm wrong, and a hacker figures out how to get past my restricted cone NAT router and finds out what my Google password is, as a free service it has no real value. Remember that we also use password authentication for SIP - granted, with a nonce, but only hashed with MD5. So, I don't think using password authentication for Google Voice with an OBi ATA presents a significant risk.
The alternative of course is to upgrade the firmware on my mission-critical out-of-warranty device that has a documented history of bricking during firmware upgrades (albeit not recent - but not non-existent), made by a manufacturer that has a history of removing features, not allowing firmware downgrade, and not providing release notes for firmware versions.
Hmm. Which should I choose?
