The Yubikey website is vague, but it seems like the lightning end only works with a few apps (1Password, Brave, etc). What do I do if I want to sign in to anything else that needs 2FA? Do I still need a TOTP app?
I really do want them to work fully though so I can extend my product to mobile too. I know a lot of people now that have gotten rid of their computers and just use their phones for everything.
