The Passwords App is accessing websites found in the ASCredentialIdentityStore associated with a 3rd Party password management app (SamuraiSafe). This behaviour appears to be associated with looking up website favicons in order to display in Passwords. However the websites contacted are not stored in the Passwords App/iCloud KeyChain - only the 3rd Party password management app (SamuraiSafe). This is effectively leaking website information stored in the 3rd Party password management app.
I first noticed this behaviour on macOS, and it appears to happen every 8 days. Today it was seen on iOS.
The behaviour is revealed through the App Privacy Report on iOS (and LittleSnitch on macOS).
I would not be surprised to see the Passwords App do this for websites saved in the Passwords App/iCloud KeyChain, however I believe it should not be arbitrarily testing every website found in the ASCredentialIdentityStore as reference to that website url should be entirely under the control of the end user.
See attached screenshots from App Privacy Report.

completeRequestWithTextToInsert is used to return text into an arbitrary textfield via the context menu AutoFill/Passwords from a 3rd party password manager (or presumably the Passwords App) in iOS 18.
While testing this feature in the debugger, it would often fail on the first invocation. It also appears to happen intermittently in the released app extension. Subsequent testing using the Passwords App shows it too may fail to return a value.
I have confirmed this behaviour is repeatable with the Passwords App on an iPhone running iOS 18.3.1
Reboot the iPhone.
Show the App Library, and right click Autofill.
Select Passwords
Select Passwords (App)
Select a password.
Nothing will be inserted (intermittently).

Hi team, if I log into my app on Safari and try to enroll/challenge MFA security key option, I will be able to see this pop-up that gives me the option to pick either passkeys or external security keys
However, my team member who's using the same version of safari, can only see the external security key option
Why is this?

Using personal physical iPhone for simulations. Can't get Keychain to read or store AppleID name/email. I want to avoid hard reseting physical phone.

iCloud Keychain Verification Codes
Hello, I have a fully functional webauthn relying party that uses passkeys and I am trying to implement an iOS sdk for it. On the server, the AASA file is valid and well served at /.well-known/assetlinks.json. I verified its validity with branch.io and that it is indeed cached by Apple's CDN (https://app-site-association.cdn-apple.com/a/v1/service.domain.com), but even will all these I still get the following error when installing the app on a device and starting the passkey ceremony:
Passkey authorization failed. Error: The operation couldn’t be completed. Application with identifier TEAM.com.APP is not associated with domain service.domain.com
So I then checked the system log when installing the app on my iPhone, and under the swcd process (which is apparently responsible of fetching the AASA file) I found the following error:
swcd: Domain is invalid. Will not attempt a download.
The issue that I have is that my domain is actually an IDN, it has a special character in it. But everywhere I have used it, I converted it to ASCII (punycode). With this conversion, Apple's CDN is able to fetch the AASA file, and the passkey ceremony works fine on a browser.
So I don't understand how the device (both iPhone or Mac) finds this domain to be invalid? In the app's entitlements, I added the capability for an associated domain, with webcredentials:service.domain.com with the domain name converted to ASCII (punycode) and developer mode doesn't address this issue as it appears when the app is installed (and is not related to Apple's CDN).
The last thing I tried was to add the domain with special characters in the app's entitlements (for webcredentials:) but then Xcode was unable to install the app on the device, and gave the following error:
Failed to verify code signature (A valid provisioning profile for this executable was not found.)
which happened only with a special character in the domain in the app's entitlements.
All this leaves me kind of in a dead end, I understand Xcode or iOS/macOS has a hard time with IDNs and special characters (so do I), but I have no idea on how to solve this (without changing the domain name), so I would really appreciate any help. Thanks in advance.
PS: I tested all this previously with another domain without special characters and it was working. It also had dashes ('-') in it and the new domain converted to ASCII is basically a regular domain with '-' in it so I suppose there is some kind of conversion made from ASCII back to special characters and that then, the domain is considered as invalid, but this doesn't really help me a lot...
PS2: My devices are running on iOS 17.4.1 and macOS 14.4.1 with Xcode 15.2

I have had a password autofill app extension in production for years.
It still works fine.
Except when the user taps a username or password textfield and selects "AutoFill" from the context menu.
They are shown a modal error dialog, stating:
"AutoFill Unavailable - The developer needs to update it to work with this feature."
I cannot find any help on this issue.
The AutoFill extension works fine when tapping the "Passwords" bar above the iOS keyboard.
Any pointers would be appreciated.
I'm working on a Password Manager app that integrates with the AutoFill Credential Provider to provide stored passwords and OTPs to the user within Safari and other apps.
Password AutoFill works perfectly.
I'm unable to get iOS to register that the app supports OTPs though.
I've followed the Apple documentation here: https://developer.apple.com/documentation/authenticationservices/providing-one-time-passcodes-to-autofill and added "ProvidesOneTimeCodes" to the AutoFill extension's Info.plist, but iOS just doesn't seem to notice the OTP support.
<key>ASCredentialProviderExtensionCapabilities</key>
<dict>
<key>ProvidesOneTimeCodes</key>
<true/>
<key>ProvidesPasswords</key>
<true/>
</dict>
Any help would be greatly appreicated!

I have my custom Authplugin implemented at login (system.login.console), and I want to remove password requirement validation/authentication from system.login.console authorization right. Do you see any functionality loss in completely removing password need at login. And is there any reference which can help me here to acheive this?
