Uzgodnienie tego Threat Model

Before writing any code, it i s essential to understand the e thre pergets you are consexing against. The password reset flow is a high- value target for attackers because it can allow them tem hijack an account with only accours to thee user 's email inbox or a leaked token. Key controls include:

Every design decision must lighete these risks. The stay der of this article detals how to adors each threat while delivering a smooth user experience.

Key Principles of a Secure Password Reset Flow

Te zasady są wysoce lewelowe, które są zgodne z tym, co robią.

Wdrożenie tej wersji Password Reset Flow in iOS

Thee following steps walk the complete client- server interaction, with specific guidance for iOS development using Swift andintegrating with Directus as thee backend.

Step 1: User Inicjates a Reset

Stworzenie uproszczonego view kiedy to user enters their ir email adresses. Validate te email format locally before sending the request to prevent unnecesary network calls. Usie english 1; Iglo1; FLT: 0 english 3; Iglomerate; with a custem delegate te te enforcement certificate pinning if desired.

func requestPasswordReset(email: String) async throws {
 guard isValidEmail(email) else { throw ValidationError.invalidEmail }
 let url = URL(string: "https://api.example.com/auth/password/request")!
 var request = URLRequest(url: url)
 request.httpMethod = "POST"
 request.setValue("application/json", forHTTPHeaderField: "Content-Type")
 let body = ["email": email]
 request.httpBody = try JSONEncoder().encode(body)
 let (_, response) = try await URLSession.shared.data(for: request)
 guard let httpResponse = response as? HTTPURLResponse,
 httpResponse.statusCode == 200 else { throw NetworkError.requestFailed }
 // Always show the same success message regardless of email existence
}

Notie that the client does nots note differentate between a registered and unregistered email; the server returns a generic 200. This prevents user enumeration.

Step 2: Backend Generates andSends a Token

In Directus, you can extend thee built- in certification endpoints or create a custem hook. The server should:

  1. Check if thee email exists (but do not reveal thee result to thee client).
  2. Generate a randem token (np., using virg1; virg1; FLT: 2 virg3; virg3; in Node.js).
  3. Store a hashed version of the token in the datase along with the user ID and d estation timestamp.
  4. Send an email containg a deep link that includes thee raw token. The link format should be something like indi1; endi1; FLT: 3 entil 3; entil3;.
  5. Wdrożenie rate limiting: allowa only one reset request per email per 60 seconds, and a maximum umf of, say, 5 requests per hour.

Using a headless CMS like Directus simplifies this because you can manage user roles, email templates, and token exationion directly the Admin Panel or via extensions.

Step 3: Token Validation via Deep Link

On iOS, handle incoming deep links using signal; Xi1; FLT: 4; XI3; OR thee newer signific.1; Xi1; FLT: 5 X3; XI3; for Universal Links. For a custem URL scheme, register district.1; FLT: 6 XI3; XI3; in the Info. PLIST AND implement Gislation 1; FLT: 7 XI3; XIX3. For extra visity, use Universaval Links Associated Domains, which prevents epr apps from bustemping the link.

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
 guard url.scheme == "yourapp", url.host == "reset-password",
 let components = URLComponents(url: url, resolvingAgainstBaseURL: false),
 let token = components.queryItems?.first(where: { $0.name == "token" })?.value else {
 return false
 }
 // Navigate to the reset password view controller with the token
 showResetPasswordView(token: token)
 return true
}

Once on thee reset view, thee app sends thee token te server for validation before showing thee new password fields. Thi prevents wasting thee user 's time if thee token is experred or malformed.

func validateToken(_ token: String) async throws -> Bool {
 let url = URL(string: "https://api.example.com/auth/password/validate")!
 var request = URLRequest(url: url)
 request.httpMethod = "POST"
 request.setValue("application/json", forHTTPHeaderField: "Content-Type")
 let body = ["token": token]
 request.httpBody = try JSONEncoder().encode(body)
 let (data, response) = try await URLSession.shared.data(for: request)
 guard let httpResponse = response as? HTTPURLResponse,
 httpResponse.statusCode == 200 else { return false }
 // You can optionally decode a response that includes the userID for later use
 return true
}

Step 4: Setting a New Password

After token validation succeeds, present the new password and confirmation fields. Enforce password delicth rules on the client (np., minimum length, deliter deliter) but always revalidate on thee server. Submit the new password alongh the token (or a session token obtained frem validation) to a final endpoint.

func resetPassword(token: String, newPassword: String) async throws {
 guard isPasswordStrong(newPassword) else { throw ValidationError.weakPassword }
 let url = URL(string: "https://api.example.com/auth/password/reset")!
 var request = URLRequest(url: url)
 request.httpMethod = "POST"
 request.setValue("application/json", forHTTPHeaderField: "Content-Type")
 let body = ["token": token, "password": newPassword]
 request.httpBody = try JSONEncoder().encode(body)
 let (_, response) = try await URLSession.shared.data(for: request)
 guard let httpResponse = response as? HTTPURLResponse,
 httpResponse.statusCode == 200 else { throw NetworkError.resetFailed }
 // Token is now invalidated; show success and navigate to login
}

Te server must hash thee new password (bcrypt, argon2, etc.) and invinidate thee reset token instantately. It should d also invinidate ane existing user sessions to force a fresh login.

Integrating wigh Directus for Backend Logic

Rev.1; Rev.1; FLT: 0 rev.3; Rev.3; Directus provides built- in support for password revists eng1; Evor1; FLT: 1 revil3; FLT: 1 revil3; PHARE REST i D GraphQL APIs. By default, it emails a token with a configuable edivation. However, for a nativie iOS app, you will likele want to customize thee flow to use deep links instead of thee default web link. Thican be revied by:

This approach allows you tu keep user management centralized in Directus while tailoring thee reset experience to iOS nativa navigation.

Begt Practices for Developers

Testing thee Password Reset Flow

Thorough testing is essential to catch edge cases and timing issues. Use the following tett texos:

Automat these tests using XCUItest for thee UI flow and unit tests for thee network layer. Also perforom a security audit with trantration testing tools to verify that tokens cannot be brute-forced or guessed.
