Unable to sign into Yahoo using a passkey

Hello everyone,

Passkeys.directory now shows that Yahoo.com supports both Sign in with passkey and Passkey MFA. Please see our entry for more details: Yahoo.com - Passkeys.directory

If you don't see the option to add a passkey then it may not yet be available for your Yahoo account, it looks like Yahoo is performing a staged rollout. If Yahoo does make passkeys available for your account then 1Password will be ready to save and sign in using that passkey.

According to passkeys.directory, currently only Yahoo.com and Yahoo.co.jp have introduced passkey support.

I think because Yahoo.JP (Japan) was one of the first companies who supported Passkeys, Yahoo was recognized to take place on the list of supported Passkeys sites.
U fortunately other Yahoo countries dit not follow this innovating initiative.

This is confusing. Yahoo doesn't allow passkeys. I'm not too interested in, "well technically they do..."

Also in The Netherlands Yahoo doesn’t support Passkeys. I tried several times to check if it should be available, but unfortunately Yahoo has no t taken steps to implement Passkeys.

I confirm that Yahoo ask for a physical key (at least in their picture), but in reality it must be asking for the passkey cause 1Password kicks in and suggests the saved passkey.

Wow that's one weird method Yahoo's using!! Indeed you're right: with them when you setup a Physical Security Key (you don't have a choice, they don't list "passkey" anywhere as a security method), it creates a Software Passkey, and of course 1Password will store it as a passkey. The problem with that confusing approach is:

1. Passkey should NOT rely on a physical key, as it's the case here
2. Their method is not standard and will mix up people (in my opinion they already are)
   At least it allow us to name the key, so it'll be easier if Yahoo ask for the physical key in the future (cause I use 3 keys)

One weird fact though: the key I inserted has a finger reader (NOT a fingerprint reader), and on every other site asking me for a key, I had to press my finger on the key to validate I'm there, but not this time. It accepted the key right away!

Yahoo, you're weird guys!!

johnnygoodface You can use passkey instead of a physical key, 1Password enabled that.
When the Yahoo website prompt for physical key, an 1Password popup will appear.
I enabled passkey using Security Key option.

Only for 2-Step Verification though.

I think they should update https://passkeys.directory since I can't login using passkey.

I know what a physical security key is, but Passkey is quite literally the same thing in software. They both implement the FIDO authentication standard. Ergo, Passkey can be used as a second factor, if that's all the site allows, no matter what the site's slow to get a clue administrators call it.

Therefore, there is no error with 1Password's alert that Passkey support is available. In the Passkey directory that 1Password maintains, there may need to be an edit done to specify whether they support both Signing and MFA, or just MFA.

I ran into the same issue you described. I'll get this mentioned to the team.

edit: It looks like it might be in a beta or something like that. https://in.help.yahoo.com/kb/SLN35635.html

Sorry to contradict you but Security Key is not a Passkey. Security key is a physical key you insert like a USB Yubikey key and you would then follow Yahoo's instructions like this:

Passkey is software only and doesn't require any physical device.
I've fully disabled my 2FA and started over again but Yahoo still only offers those 3 options above, and none of it is Passkey.

I guess the correct question is: "why is Yahoo listed in the Passkey directory (https://passkeys.directory/details/yahoo/)?" because this is probably why 1Password is tricked into thinking Passkey is available for Yahoo.
