I am developing an Authorization plugin for macOS that should be invoked when a user unlocks their device from the lock screen. Based on advice from the other threads in these forums, I have understood that: The plugin needs to use SFAuthorizationPluginView The auth db entries to modify are system.login.screensaver and authenticate I found the NameAndPassword sample and after making some tweaks to it was able to get it to work from screensaver unlock. I am trying to add Webview-based authentication to the plugin, but have not had any success. The plugin window's width does not change (though the height does) and only a small portion of the HTML gets rendered. Is Webview-based authentication supported with SFAuthorizationPluginView? Are there any alternatives?

We are experiencing a significant issue with macOS security alerts that began on July 9th, at approximately 4:40 AM UTC. This alert is incorrectly identifying output files from our snippet tests as malware, causing these files to be blocked and moved to the Trash. This is completely disrupting our automated testing workflows. Issue Description: Alert: We are seeing the "Malware Blocked and Moved to Trash" popup window. Affected Files: The security alert triggers when attempting to execute .par files generated as outputs from our snippet tests. These .par files are unique to each individual test run; they are not a single, static tool. System-Wide Impact: This issue is impacting multiple macOS hosts across our testing infrastructure. Timeline: The issue began abruptly on July 9th, at approximately 4:40 AM UTC. Before that time, our tests were functioning correctly. macOS Versions: The problem is occurring on hosts running both macOS 14.x and 15.x. Experimental Host: Even after upgrading an experimental host to macOS 15.6 beta 2, the issue persisted. Local execution: The issue can be reproduced locally. Observations: The security system is consistently flagging these snippet test output files as malware. Since each test generates a new .par file, and this issue is impacting all generated files, the root cause doesn't appear to be specific to the code within the .par files themselves. This issue is impacting all the snippet tests, making us believe that the root cause is not related to our code. The sudden and widespread nature of the issue strongly suggests a change in a security database or rule, rather than a change in our testing code. Questions: Could a recent update to the XProtect database be the cause of this false positive? Are there any known issues or recent changes in macOS security mechanisms that could cause this kind of widespread and sudden impact? What is the recommended way to diagnose and resolve this kind of false positive? We appreciate any guidance or assistance you can provide. Thank you.

Hi everyone, I am trying to use ASWebAuthenticationSession to authorize user using OAuth2. Service Webcredentials is set. /.well-known/apple-app-site-association file is set. When using API for iOS > 17.4 using new init with callback: .https(...) everything works as expected, however i cannot make .init(url: ,callbackURLScheme: ....) to work. How can i intercept callback using iOS <17.4? Do I really need to use universal links? callbackURL = https://mydomain.com/auth/callback

I have a launch daemon that's using the Endpoint Security framework which also is causing high memory usage (in Activity Monitor memory column shows for example 2GB and Real Memory 11MB) when building a big project in Xcode. Is it some kind of memory caching by the system? leaks -forkCorpse seems to not show any leaks. How can I attach with heap or Instruments without the process being killed with "ENDPOINTSECURITY, Code 2 EndpointSecurity client terminated because it failed to respond to a message before its deadline"?

I have been able to save and remove ASPasskeyCredentialIdentities in the ASCredentialIdentityStore. But after saving a ASPasskeyCredentialIdentity, when I retrieve the current identities stored, it always returns an empty list. I check to make sure the store is enabled. I am using this method which is available starting with iOS 17.4: extension ASCredentialIdentityStore { public func credentialIdentities(forService serviceIdentifier: ASCredentialServiceIdentifier? = nil, credentialIdentityTypes: ASCredentialIdentityStore.IdentityTypes = []) async -&gt; [any ASCredentialIdentity] } I have called it like this: store.credentialIdentities(forService: nil, credentialIdentityTypes: .passkey) And this: store.credentialIdentities() Has anyone got this to work?

Hi, A user logs in to the file vault, and DisableFDEAutoLogin is false. The file vault login succeeds, but the login to the selected user fails. The user gets the login screen again. If the user puts an invalid password to try and login again, the loginwindow:FDESupport plugin will change the user's password to the invalid one.

Hi , I have a requirement like, Develop an app for iPad and app uses .net core apis. App will be in kiosk mode, and app doesn't have any type of authentication even OTP also. As the apis will be publishing to all over internet, how can we achieve security to apis? Kindly provide suggestions for this implementation

I am developing a sample authorization plugin to sync the user’s local password to the network password. During the process, I prompt the user to enter both their old and new passwords in custom plugin. After the user enters the information, I use the following code to sync the passwords: try record.changePassword(oldPssword, toPassword: newPassword) However, I have noticed that this is clearing all saved keychain information, such as web passwords and certificates. Is it expected behavior for record.changePassword to clear previously stored keychain data? If so, how can I overcome this issue and ensure the keychain information is preserved while syncing the password? Thank you for your help!

Hi, I am creating a custom login window, so I am using SFAuthorizationpluginView, here I want to hide Submit Arrow botton which gets displayed beside username and password text feild , is there a way to hide this, please suggest.

I'm trying to setup device attestation. I believe I have everything setup correctly but the final step of signature validation never succeeds. I've added validation on the client side for debugging and it doesn't validate using CryptoKit. After the assertion is created, I try to validate it: assertion = try await DCAppAttestService.shared.generateAssertion(keyId, clientDataHash: clientDataHash) await validateAssertionLocallyForDebugging(keyId: keyId, assertionObject: assertion, clientDataHash: clientDataHash) In the validateAssertionLocallyForDebugging method, I extract all the data from the CBOR assertionObject and then setup the parameters to validate the signature, using the key that was created from the original attestation flow, but it fails every time. I'm getting the public key from the server using a temporary debugging API. let publicKeyData = Data(base64Encoded: publicKeyB64)! let p256PublicKey = try P256.Signing.PublicKey(derRepresentation: publicKeyData) let ecdsaSignature = try P256.Signing.ECDSASignature(derRepresentation: signature) let digestToVerify = SHA256.hash(data: authenticatorData + clientDataHash) print(" - Recreated Digest to Verify: \(Data(digestToVerify).hexDescription)") if p256PublicKey.isValidSignature(ecdsaSignature, for: digestToVerify) { print("[DEBUG] SUCCESS: Local signature validation passed!") } else { print("[DEBUG] FAILED: Local signature validation failed.") } I have checked my .entitlements file and it is set to development. I have checked the keyId and verified the public key. I have verified the public key X,Y, the RP ID Hash, COSE data, and pretty much anything else I could think of. I've also tried using Gemini and Claude to debug this and that just sends me in circles of trying hashed, unhashed, and double hashed clientData. I'm doing this from Xcode on an M3 macbook air to an iPhone 16 Pro Max. Do you have any ideas on why the signature is not validating with everything else appears to be working? Thanks

Hi, We are using the MSAL library to authenticate users, with SSO authentication implemented through the Microsoft Authenticator app. The problem is that once or twice a day, a prompt for forced authentication appears, indicating that silent token acquisition is failing and resulting in a requirement for forced authentication. Below are some of the logs: ================================================= 2025-08-28 11:00:05.034 [Info] [AppDelegate.swift:121] application(:didFinishLaunchingWithOptions:) > MSAL message: TID=751353 MSAL 1.8.1 iOS 18.5 [2025-08-28 10:00:05 - EC9D1457-2D70-4878-926F-553391EBC9D3] [MSAL] Silent flow finished. Result (null), error: -51115 error domain: MSIDErrorDomain 2025-08-28 11:00:05.034 [Info] [AppDelegate.swift:121] application(:didFinishLaunchingWithOptions:) > MSAL message: TID=751353 MSAL 1.8.1 iOS 18.5 [2025-08-28 10:00:05 - EC9D1457-2D70-4878-926F-553391EBC9D3] [MSAL] acquireTokenSilent returning with error: (MSALErrorDomain, -50002) Masked(not-null) ==================================================== We initially raised this issue with Microsoft, but according to them: In the app's logs, the single one failure it contains, was when the SSO extension returned the error com.apple.AuthenticationServices.AuthorizationError, -6000 during a silent call. This error code is generated by the system framework (Apple), not by our code. It indicates that the framework encountered an unexpected internal issue before or after calling the SSO extension. MSAL returning interaction_required to the client app is the most effective way to recover from this error (as you mention, after the user selects the account the app continues working as expected). Additionally, as you also mention, the interactive call is made by switching to Authenticator (not displaying a "window" without leaving Eva Lite app), which means MSAL is not able to use the SSO extension and is using the fallback to legacy authentication. The recommended next step is for the customer to request support directly from Apple as this is an issue on their side. Additionally, the customer can also try to update to the latest iOS, in case Apple has already fixed this issue. ============================================= STEPS TO REPRODUCE There is no such steps its just that this is an enterprise application which is getting used on managed devices[iPhone 14]. The device are managed using some intune policy. Platform and Version: iOS Development Environment: Xcode 15, macOS 13.6.1 Run-time Configuration: iOS 18 Please let me know if there are any solutions to resolve this problem. Thank you.

Hey all, Question for the masses.... Does the Yubikey authentication have a OS dependency and it only works with a stable, public OS? Does Azure/Okta/Yubikey beta OS26? My CEO installed iPadOS 26 on his iPad and was not able to authenticate via Yubikey into our company environment. I ran the same scenario on my iPad using iPadOS 26 and I had the same results. Downgrading to iPAdOS doesn't pose these issues. I'm assuming something isn't fine-tuned yet?

Hello everyone, In my application, i have implemented authentication using ASWebauthenticationSession. However, when redirecting the user to a WKWebView, no cookies are shared, causing the session to be lost and requiring the user to log in again. Is there a way to share cookies between the two? If not, what would be the best approach to set up authentication that ensures SSO when switching to a WebView ? Thank you very much for your help !

Why are we doing this nonsense? We want to be able to run builds in a sandbox such that they can only see the paths they are intended to depend on, to improve reproducibility. With builds with a very large number of dependencies, there's a very large number of paths added to the sandbox, and it breaks things inside libsandbox. Either it hits some sandbox length limit (sandbox-exec: pattern serialization length 66460 exceeds maximum (65535), Nix issue #4119, worked around: Nix PR 12570), or it hits an assert (this report; also Nix issue #2311). The other options for sandboxing on macOS are not viable; we acknowledge sandbox-exec and sandbox_init_with_parameters are deprecated; App Sandbox is inapplicable because we aren't an app. Our use case is closer to a browser, and all the browsers use libsandbox internally. We could possibly use SystemExtension or a particularly diabolical use of Virtualization.framework, but the former API requires notarization which is close to a no-go for our use case as open source software: it is nearly impossible to develop the software on one's own computer, and it would require us to ship a binary blob (and have the build processes to produce one in infrastructure completely dissimilar to what we use today); it also requires a bunch of engineering time. Today, we can pretend that code signing/notarization doesn't exist and that we are writing an old-school Unix daemon, because we are one. The latter is absolutely diabolical and hard to implement. See this saga about the bug we are facing: Nix issue #4119, Nix issue #2311, etc. What is going wrong I can't attach the file fail.sb as it is too large (you can view the failing test case at Lix's gerrit, CL 2870) and run this: $ sandbox-exec -D _GLOBAL_TMP_DIR=/tmp -f fail.sb /bin/sh Assertion failed: (diff &lt;= INSTR_JUMP_NE_MAX_LENGTH), function push_jne_instr, file serialize.c, line 240. zsh: abort sandbox-exec -D _GLOBAL_TMP_DIR=/tmp -f fail.sb /bin/sh Or a stacktrace: stacktrace.txt Credits Full credits to Jade Lovelace (Lix) for writing the above text and filing a bug.

We are using Apple's PSSO to federate device login to out own IdP. We have developed our own extension app and deployed it using MDM. Things works fine but there are 2 issues that we are trying to get to the root cause - On some devices after restarting we see an error message on the logic screen saying "The registration for this device is invalid and must be repaired" And other error message is "SmartCard configuration is invalid for this account" For the 1st we have figured out that this happens when the registration doesn't happen fully and the key is not tied to the user so when the disk needs to be decrypted at the FileVault screen the issue is raised. For the "SmartCard configuration is invalid for this account" issue also one aspect is invalid registration but there has been other instances as well where the devices were registered completely but then also the the above error was raised. We verified the registration being completed by checking if the SmartCard is visible in the System Report containing the key. Has anyone seen the above issues and any possible resolution around it?

My application is supporting hybrid transport on FIDO2 webAuthn specs to create credential and assertion. And it support legacy passkeys which only mean to save to 1 device and not eligible to backup. However In my case, if i set the Backup Eligibility and Backup State flag to false, it fails on the completion of the registrationRequest to save the passkey credential within credential extension, the status is false instead of true. self.extension.completeRegistrationRequest(using: passkeyRegistrationCredential) The attestation and assertion flow only works when both flags set to true. Can advice why its must have to set both to true in this case?

Hello everyone. Hope this one finds you well) I have an issue with integrating a FIDO2 server with ASAuthorizationController. I have managed to register a user with passkey successfully, however when authenticating, the request for authentication response fails. The server can't validate signature field. I can see 2 possible causes for the issue: ASAuthorizationPlatformPublicKeyCredentialAssertion.rawAuthenticatorData contains invalid algorithm information (the server tries ES256, which ultimately fails with false response), or I have messed up Base64URL encoding for the signature property (which is unlikely, since all other fields also require Base64URL, and the server consumes them with no issues). So the question is, what encryption algorithm does ASAuthorizationController use? Maybe someone has other ideas regarding where to look into? Please help. Thanks)

Hi everyone, I’m working an Objective-C lib that performs Keychain operations, such as generating cryptographic keys and signing data. The lib will be used by my team in a Java program for macOS via JNI. When working with the traditional file-based Keychain (i.e., without access control flags), everything works smoothly, no issues at all. However, as soon as I try to generate a key using access control flags SecAccessControlCreateWithFlags, the Data Protection Keychain returns error -34018 (errSecMissingEntitlement) during SecKeyCreateRandomKey. This behavior is expected. To address this, I attempted to codesign my native dynamic library (.dylib) with an entitlement plist specifying various combinations of: keychain-access-groups com.apple.security.keychain etc. with: My Apple Development certificate Developer ID Application certificate Apple Distribution certificate None of these combinations made a difference, the error persists. I’d love to clarify: Is it supported to access Data Protection Keychain / Secure Enclave Keys in this type of use case? If so, what exact entitlements does macOS expect when calling SecKeyCreateRandomKey from a native library? I’d really appreciate any guidance or clarification. Thanks in advance! Best regards, Neil
