Show HN: RecoveryCodes – MFA inventory for auth outside IdPs

Hi HN,

Over the last few months, I invested pretty heavily into setting up SSO for my self-hosted stack. However, some apps gate SSO behind paid plans, meaning accounts and thus MFA need to be set up outside of the IdP. This leaves me with a weird mix of accounts handled by the IdP and those that I need to track manually.

There wasn't really a good way to track this mixture, especially once you add multiple MFA devices and sensitive data like recovery codes, because the IdP has one half and the password manager has the other (+ maybe it's the second factor itself).

That's why I built RecoveryCodes. It allows me to track all my accounts, see which MFA devices I've enrolled (I usually enrol 2 per account, in case one is lost) and also gives me a place to store recovery codes (instead of copy pasting them into a random .txt file).

Obviously I'm n=1, so I'm interested in hearing from slightly larger companies how you're dealing with this mix? Spreadsheets maybe, or are most of the accounts covered by IdPs and the rest don't really matter?
