I feel like a boomer.

I dont want to use google/apple/microsoft for any credential manager because: google is evil; apple has locked me out of my apple id (and lost things like the recordings of conversations with my father during his hospice); microsoft keeps getting worse and more annoying to use.

So ok, I need some credential manager. I used keepass previously... but how do I vet other credential managers? I dont want an online backup. I want my credentials to only be on my computers. So now I gotta learn about which apps are ok, don't have cloud synching, can export files, and be compatible with MacOS.

And I have to learn what is FIDO? Like FICO? why do I need to synch with FIDO? what is it? will it give my credential store to others?

How is this easier or more convenient than a user/pass with 2fa?

I feel like I am going to accidentally leak my credentials and have no way of knowing
