How about login.gov? Govt run. Very well done. Already used bu multiple federal agencies. Seems like a shoe in. Throw out ID.me and return their lobbying dollars for good measure.
What I don't understand is why any customer of id.me believes id.me's characterization of how much fraud there is, and how effective they are. How many of id.me's claims have been independently verified?
Login.gov supports and encourages security keys (yubikey etc) as 2FA. I hope it does see wider adoption soon by more agencies, esp IRS.
