Unable to sign into Yahoo using a passkey

Security Key = Passkey, though in this case Yahoo may only allow you to use it for 2FA, rather than an authenticator app, instead of completely handling login. I seem to remember, however, being able to sign in with a passkey alone, once I removed my authenticator app 2FA.

Not all sites have upgraded to allow Security Keys/Passkeys for complete 1 step login. However, even on those you can still create a security key, which 1Password will store as a Passkey, and eliminate having to fill an auth key. Presumably, if they aren't knuckle heads about it, once a site enables 1 step passkey login, the passkey you setup via their security key option will 'just work'.

I've turned off the Account Key, and now it only offers those choices when I turn on 2-step verification:

So clearly Yahoo doesn't offer passkeys yet (at least in Canada)

Hi there johnnygoodface

There is an entry for Yahoo! on our https://passkeys.directory website:

☞ https://passkeys.directory/details/yahoo/

As noted in its listing there, you might need to remove any authenticator apps you have set up for Yahoo! before you'll be able to save a passkey. Give that a try if you haven't already and let me know if following the link on the Passkeys.directory listing helps too. :)
