Passkey autofill stopped working on iOS 17.4 ASWebAuthenticationSession

[Nov Matake]

FYI:

Since iOS 17.4, passkey autofill seems stopped working inside ASWebAuthenticationSession.

plus, `excludeCredentials` option also stopped working on iOS 17.4, and it’s not only in ASWebAuthenticationSession but also in Safari.

Passkey autofill not working properly on iOS seriously harms the passkey experience. Would love to hear if it is being addressed.

So after additional investigation, I can see that this is specific to iCloud Keychain. When having alternative password/passkey managers enabled, it works fine, however iCloud Keychain does not return any credentials.

Still broken on my side o_O. How did you get it running?

Yeah, I don’t think normal user choose passkey in this UI.

In our service, we support passkey autofill only, thus our passkey usage became 1/2 on our iOS native apps after iOS 17.4 release :(

Upgraded to iOS 17.5, and open Safari password manager via the key icon on the top right of the keyboard.

Then you’ll see registered passkeys.

It’s not perfect at all, but somehow, you can choose your passkey…

At least, better than iOS 17.4, where I lost passkey access at all.
