Hi, I know it's been discussed before, but I'm testing the Sign in with Apple feature, and I only get the user info on the first try. Now, I know that you're supposed to go to the account settings, and look for the list of accounts that you used your Apple account to sign in with, and it used to work a few months back. But for the last few weeks I haven't been able to get the user info, even after deleting the entry from my Sign In With Apple app list. Has there been a recent change to Apple security policy that prevents such a move from working ? Or am I doing something wrong ? Thank you

Feedback report id: FB16605524 I'm trying to send emails to private relay service addresses using AWS SES and emails are not received. My emails are sent from dev@mydomain.fr and I've set a custom FROM domain of mail.mydomain.fr. I've added both domains and the dev@mydomain.fr adress to the "Certificates, Identifies & Profiles" section. I've set up DKIM and SPF for both. Attached a redacted version of email headers. email_headers_redacted.txt

I set up "Sign in with Apple" via REST API according to the documentation. I can log in on my website and everything looks fine for the user. But I receive an email, that my "Sign in with Apple" account has been rejected by my own website. It states, I will have to re-submit my name and email address the next time I log in to this website. I don't see any error messages, no log entries, no HTTP errors anywhere. I also can't find anything in the docs, the emails seem to not be mentioned there, searching for anything with "rejected" in the forum did not yield any helpful result, because they are always about App entries being rejected etc. Did someone experience something similar yet? What's the reason, I'm getting these emails? I get them every time I go through the "Sign in with Apple" flow on my website again.

We're integrating Sign in with Apple into our iOS app The Apple ID login UI appears correctly on real devices, but after tapping Continue, the system immediately stops and shows code 1001. This issue happens across multiple devices and Apple ID accounts, even with no prior login history. We’ve confirmed the following Sign in with Apple is enabled in both Developer Portal and Xcode Capabilities Automatic signing and provisioning are set correctly Device is signed into iCloud and system time is synced Performed clean build, app reinstall, and other standard debugging steps We suspect that the sign in handshake process may not be completing properly due to some kind of account or server-side restriction, and we’d appreciate any insights into this behavior.

I’m considering storing some sensitive information in the userID field of a passkey, as described in the createCredentialRegistrationRequest method.(link to method). I'm aware of the largeBlob extension introduced in iOS 17+, but it doesn't meet my needs since I want to create a cross-platform passkey that can be used across various devices — and currently, not many devices support the largeBlob extension. According to W3C documentation, the userID field is not considered private information and can be displayed to the user without requiring a verification process. Based on my understanding, it's also not encrypted, which means it might be accessible with physical access to the device. So here are my questions: How do Apple devices (especially iPhones) handle the userID field in their authenticators? Is it possible to access the userID without user verification, as permitted by the W3C specification? Are there any alternative methods to access the userID value stored in a passkey on Apple devices?

During SmartCard pairing the PIN prompt enables the OK button only on user provides a PIN of 6 digits. Is there a way to submit the empty PIN in this flow, where the custom CTK is used here (the custom CTK would take care of the PIN from the custom ctk code). I was able to do an empty PIN submit once the I've paired the user successfully at login, unlock and other cli tools. Is there a way to do the same during the pairing? Once the user has successfully paired with the SmartCard authentication with PIN, I was able to see most of the authentication flows was prompting for the PIN authentication like login, unlock, CLI tools like ssh, su etc., perhaps at few apps where it is still prompted with the Password instead of PIN examples, when I tried to launch Keychain Access app or Add a user from users&groups system setting. Is this expected behaviour?

I have a user (myself, during development) who originally signed in with Apple successfully. I attempted to revoke access via Settings > Apple ID > Sign-In & Security > Sign in with Apple, but the app appears stuck in the list and cannot be fully removed. Now when attempting to sign in again, the identity token contains the correct sub but email is undefined. According to Apple's documentation, "Apple provides the user's email address in the identity token on all subsequent API responses." I've tried programmatically revoking via the /auth/revoke endpoint (received 200 OK), and I've implemented the server-to-server notification endpoint to handle consent-revoked events, but subsequent sign-in attempts still return no email. The same Apple ID works fine with other apps. Is there a way to fully reset the credential state for a specific app, or is this a known issue with partially-revoked authorizations?

I would like to confirm about fraud prevention using Device Check when publishing multiple apps. If the Team ID and Key ID are the same, will the values be shared across all apps with Device Check? With Device Check, only two keys can be created per developer account, and these two are primarily intended for key renewal in case of a leak, rather than for assigning different keys to each app, correct? If both 1 and 2 are correct, does that mean that Device Check should not be used to manage "one-time-only rewards per device" when offering them across multiple apps? Thank you very much for your confirmation.

Estou compartilhando algumas observações técnicas sobre Crash Detection / Emergency SOS no ecossistema Apple, com base em eventos amplamente observados em 2022 e 2024, quando houve chamadas automáticas em massa para serviços de emergência. A ideia aqui não é discutir UX superficial ou “edge cases isolados”, mas sim comportamento sistêmico em escala, algo que acredito ser relevante para qualquer time que trabalhe com sistemas críticos orientados a eventos físicos. Contexto resumido A partir do iPhone 14, a Detecção de Acidente passou a correlacionar múltiplos sensores (acelerômetros de alta faixa, giroscópio, GPS, microfones) para inferir eventos de impacto severo e acionar automaticamente chamadas de emergência. Em 2022, isso resultou em um volume significativo de falsos positivos, especialmente em atividades com alta aceleração (esqui, snowboard, parques de diversão). Em 2024, apesar de ajustes, houve recorrência localizada do mesmo padrão. Ponto técnico central O problema não parece ser hardware, nem um “bug pontual”, mas sim o estado intermediário de decisão: Aceleração ≠ acidente Ruído ≠ impacto real Movimento extremo ≠ incapacidade humana Quando o classificador entra em estado ambíguo, o sistema depende de uma janela curta de confirmação humana (toque/voz). Em ambientes ruidosos, com o usuário em movimento ou fisicamente ativo, essa confirmação frequentemente falha. O sistema então assume incapacidade e executa a ação fail-safe: chamada automática. Do ponto de vista de engenharia de segurança, isso é compreensível. Do ponto de vista de escala, é explosivo. Papel da Siri A Siri não “decide” o acidente, mas é um elo sensível na cadeia humano–máquina. Falhas de compreensão por ruído, idioma, respiração ofegante ou ausência de resposta acabam sendo interpretadas como sinal de emergência real. Isso é funcionalmente equivalente ao que vemos em sistemas automotivos como o eCall europeu, quando a confirmação humana é inexistente ou degradada. O dilema estrutural Há um trade-off claro e inevitável: Reduzir falsos negativos (não perder um acidente real) Aumentar falsos positivos (chamadas indevidas) Para o usuário individual, errar “para mais” faz sentido. Para serviços públicos de emergência, milhões de dispositivos errando “para mais” criam ruído operacional real. Por que isso importa para developers A Apple hoje opera, na prática, um dos maiores sistemas privados de segurança pessoal automatizada do mundo, interagindo diretamente com infraestrutura pública crítica. Isso coloca Crash Detection / SOS na mesma categoria de sistemas safety-critical, onde: UX é parte da segurança Algoritmos precisam ser auditáveis “Human-in-the-loop” não pode ser apenas nominal Reflexões abertas Alguns pontos que, como developer, acho que merecem discussão: Janelas de confirmação humana adaptativas ao contexto (atividade física, ruído). Cancelamento visual mais agressivo em cenários de alto movimento. Perfis de sensibilidade por tipo de atividade, claramente comunicados. Critérios adicionais antes da chamada automática quando o risco de falso positivo é estatisticamente alto. Não é um problema simples, nem exclusivo da Apple. É um problema de software crítico em contato direto com o mundo físico, operando em escala planetária. Justamente por isso, acho que vale uma discussão técnica aberta, sem ruído emocional. Curioso para ouvir perspectivas de quem trabalha com sistemas similares (automotivo, wearables, safety-critical, ML embarcado). — Rafa

I must be missing something. How can an iphone that is in lockdown mode, using ONLY data, no Bluetooth connected and only one singular iPhone have seven UNLISTED items on the local network in privacy and settings?

Hello, I am implementing "Sign in with Apple" on my backend and validating the Identity Token (JWT) received from the client. I noticed that for some users who choose the "Hide My Email" option, the is_private_email claim is missing from the ID Token payload, even though the email address clearly belongs to the private relay domain (@privaterelay.appleid.com). Here is an example of the decoded payload I received: { "iss": "https://appleid.apple.com", "aud": "xxx", "exp": 1764402438, "iat": 1764316038, "sub": "xxxxxxxx", "c_hash": "3FAJNf4TILzUgo_YFe4E0Q", "email": "xxx@privaterelay.appleid.com", "email_verified": true, "auth_time": 1764316038, "nonce_supported": true // "is_private_email": true <-- This field is missing } My Questions: Is the is_private_email claim considered optional in the ID Token? Is it safe and recommended to rely solely on the email domain suffix (@privaterelay.appleid.com) to identify if a user is using a private email? Any insights or official references would be appreciated. Thanks.

Developers of our e-shop are preparing to enable Apple Sign In for account login. Apple ID verification is conducted via the domain appleid.apple.com, and the responses should be coming back from the following two Apple IP addresses: IPv4 Address: 17.32.194.6 IPv4 Address: 17.32.194.37 Question is whether these addresses are correct and if they remain unchanged over time. Alternatively, it is existing an official list of IP addresses that may be used for Apple Sign In verification response? This is necessary to ensure precise network communication settings and protection by F5 security solution. Thanks a lot for answers.

I’m using Sign in with Apple in my iOS app. When a user chooses “Hide My Email”, I receive the @privaterelay.appleid.com relay address. For marketing reasons, I would prefer to have the user’s real email address instead of the relay email. I want to stay compliant with App Store Review and the Sign in with Apple design/UX requirements. My questions are: Is it allowed to force the user (as part of the registration process) to provide their real email address, even if they chose “Hide My Email” during Sign in with Apple? Are there any specific App Store Review guidelines that forbid: Blocking sign up or access to features if the user keeps the relay email, or Showing a strong prompt like “We can’t log you in unless you share your real email”? What is the recommended, compliant pattern for collecting a “real” email when using Sign in with Apple + Private Relay? I’d appreciate any official clarification or examples of what App Review considers acceptable vs. reject-worthy here.

Hello, We are working on integrating app integrity verification into our service application, following Apple's App Attest and DeviceCheck guide. Our server issues a challenge to the client, which then sends the challenge, attestation, and keyId in CBOR format to Apple's App Attest server for verification. However, we are unable to reach both https://attest.apple.com and https://attest.development.apple.com due to network issues. These attempts have been made from both our internal corporate network and mobile hotspot environments. Despite adjusting DNS settings and other configurations, the issue persists. Are there alternative methods or solutions to address this problem? Any recommended network configurations or guidelines to successfully connect to Apple's App Attest servers would be greatly appreciated. Thank you.

Hello, I'm receiving an unknown error instead of the excluded credentials error when using the "Save on another device" option for Passkey creation. When creating the ASAuthorizationPlatformPublicKeyCredentialProvider request to pass to the ASAuthorizationController. The excludedCredentials property is used to add a list of credentials to exclude in the registration process. This is to prevent duplicate passkeys from being created if one already exists for the user. When trying to create a duplicate passkey using the same device, the ASAuthorizationControllerDelegate method authorizationController(controller, didCompleteWithError:) is called. The error received has localized description “At least one credential matches an entry of the excludeCredentials list in the platform attached authenticator." When trying to create a duplicate passkey using the “Save on another device” option. The delegate method is called, but the error received has code 1000 ("com.apple.AuthenticationServices.AuthorizationError" - code: 1000). Which maps to the unknown error case in ASAuthorization error type.

Our business model is to identify Frauds using our advanced AI/ML model. However, in order to do so we need to collect many device information which seems to be ok according to https://developer.apple.com/app-store/user-privacy-and-data-use/ But it's also prohibited to generate a fingerprint, so I need more clarification here. Does it mean I can only use the data to identify that a user if either fraud or not but I cannot generate a fingerprint to identify the device? If so, I can see many SKD in the market that generates Fingerprints like https://fingerprint.com/blog/local-device-fingerprint-ios/ and https://shield.com/?
