It's this classic: https://xkcd.com/927/
There's already ID.me. Why add a new thing?
Because ID.me is a for profit company, and Login.gov is accountable to citizens as a GSA product. We swap out suboptimal solutions for more optimal solutions as the situation dictates.
I get the desire to upgrade, and I'm guessing there's a good reason the ID.me logins can't be migrated to Login.gov. But it's very rare and unsettling for login method and creds to change on a site. I've pretty much only seen that on govt websites... and botched Microsoft acquisitions. So there should be a high bar for this, and I hope Login.gov is really the last time.

Me too.
Because the part of ID.me that says
> I accept the ID.me Terms of Service and Privacy Policy *
I absolutely do not and will not. Their terms are a load of BS. Horrible terms, horrible company.
