> [login.gov] if its good enough for ~342M Americans

I am very curious about the actual number of users of login.gov.

I am a US citizen and my experience was … negative to the point of actively avoiding it.

"Login.gov has surpassed 100 million registered user accounts. The platform facilitates over 300 million sign-ins annually and sees more than 10 million monthly active users, acting as a secure single sign-on solution across nearly 50 federal, state, and local agencies."

(It is the primary identity provider for Social Security Administration, IRS will eventually adopt it [1])

I have multiple login.gov accounts. They don’t let you change your primary email, so if you’re using corporate account and switch jobs the normal thing is to create new accounts. I’m sure this is padding their numbers.

If you must use login.gov for Social Security, and you will eventually be required to use it for the IRS (and everyone who has a US tax liability), I think the numbers are somewhat irrelevant. Almost everyone over the age of 18 will be a customer of it (for federal tax and benefits logistics). It is the idp you must use, and again, it is good enough (based on all available evidence).
