Root user MFA failing.
In case it matters to this question - this is a small, single user account. The majority of my AWS spend is domain registry costs, a couple of lambdas, dynamodb and some R53. That's about it. Average monthly spend is around $10.
I use a password manager (1Password in this case).
I have my root account separate from the main admin-level account I use day-to-day. Haven't needed to login to root account for a long time.
I have no problem logging into my admin account (IAM), which of course also has 2FA, and I use 1Password to store the credentials. Sign-in works.
I wanted to make some account/organizational changes, so I attempted to login to my root user. User & password accepted, but keep failing on MFA.
I'm not signed up for any support plan, so not sure how to proceed here.
