Authentication

Overview

After the SDK is initialized, you need to login to the Pango platform to be able to start VPN. Available login options may depend on the platform setup for your organization.

Pango Authentication

Pango Auth provides managed user authentication without requiring you to deploy and maintain your own OAuth server.

Benefits of Pango Auth:

• No need to deploy or maintain your own authentication server

• Managed user creation and authentication handled by Pango

• Simple token-based integration with the VPN SDK

• Supports access token refresh for seamless user sessions

Steps to implement Pango Auth:

1. Obtain your Project ID and API credentials from the Pango Developer Console.

2. Create users via the Pango Auth API (typically done on your backend server).

3. Sign in users to obtain access tokens (can be done client-side with Public API key).

4. Use the access token with AuthMethod.pango(accessToken) to login to the VPN SDK.

See the platform-specific tabs below for code examples.

Pango Authentication Example

Use the access token obtained from Pango Auth to login to the VPN SDK.

import VPNApplicationSDK
// ...
let unifiedSDK: ManualSwitchingVPNSDK // or AutoSwitchingVPNSDK
// ...
// Use the access token from Pango Auth sign-in
let authMethod = AuthMethod(type: .pango, token: "PANGO_ACCESS_TOKEN")
unifiedSDK.login(method: authMethod) { error, user in
    print("isLogged: \(error == nil)")
}

Token Considerations

When you login with token, you don't need to refresh it, it can be re-used. However it can be invalidated for some reason (login with same device id...etc).

In case you receive one of following errors:

• PartnerAPI.APIError.notAuthorized - The token of user is invalid/expired.

• PartnerAPI.APIError.unauthorized - This user is unauthorized or login operation is still pending.

then you need to initiate login again, and call SDK login(method: AuthMethod, completion: @escaping UserCompletion) again with new token.
