Third-party login options App Review checklist

Inventory login providers and account states

List email, phone, Sign in with Apple, Google, Facebook, enterprise SSO, school login, passkeys, magic links, hardware-based identity, and any region-specific provider. Then map which features each account type can access.

If the app presents a third-party login button, the review account should not depend on the reviewer's personal identity or a private enterprise tenant.

Check login parity and fallback

• Equivalent account creation and sign-in routes where policy or product promises require parity.
• Clear fallback when a provider is down, blocked, unavailable in a region, or missing required scopes.
• Account deletion, logout, reauthentication, and email relay states.
• Reviewer credentials for enterprise, school, hardware, or invite-only systems.
• Privacy labels and policy coverage for identity data shared by providers.

Make reviewer access deterministic

Provide a direct account path in Review Notes when social or enterprise login might fail from Apple's test environment. Do not require a reviewer to request an invite, approve an email domain, or join an organization manually.

AppReviewReady interpretation: a login provider may be valid for production users and still be a poor review path if it hides the app's core functionality.

Test identity edge states

1. Fresh install, existing account, deleted account, revoked provider permission, provider outage, and network failure.
2. Switch between login providers tied to the same email or account.
3. Check account deletion and data export after provider unlinking.
4. Test child, enterprise, region, or paid-account states where relevant.
5. Verify support can recover users without weakening account security.

Login option map

Keep the map current when adding providers or moving to passkeys. Identity changes often affect support, privacy labels, and account deletion at the same time.

After launch, monitor failed login attempts by provider and region. A provider-specific failure can look like a traffic problem, conversion problem, or App Review access problem depending on when it appears.

If a provider requires app verification, domain ownership, redirect URI approval, or enterprise administrator consent, complete that work before submission. A login button that works only for the developer's account is not review-ready.

For B2B or school apps, provide a demo organization with realistic permissions. Reviewers should not need to wait for a tenant admin, sales representative, or IT department to approve access.

When account linking is supported, test duplicate email, hidden email, provider unlink, and deleted-provider states. Identity edge cases often break account deletion, purchase restore, and support recovery together.
