I've already gone through the process of singing up for the IRS credentials using ID.me. Yes, you need to provide a photo of yourself, and just about any snapshot will do. You also need to provide some form of government issued Id with a photo on it, like a driver's license or passport. But once ID.me finishes vetting you, there is no facial recognition required for logging in to the IRS website. Rather, you use a common authenticator, like Authy, to enter a one-time pass code. This is not facial recognition. Rather, it is not unlike signing up for a new bank account. Banks also require facial ID to open an account. I don't see the problem with that, either. But neither then banks nor the IRS are using facial recognition technology for logging in to their portals.
