How to Use Client Certificates to Validate Mobile Apps, protect against bots


Learn how to use mobile client certificates to ensure that only validated apps can connect to your backend servers.


Mobile apps connect to all sorts of external services. They connect to their host server to authenticate users, to download content, to connect to other mobile resources, and more. Mobile apps also connect to 3rd party services embedded in the app, such as payment providers, analytics vendors, location services, and more. As a mobile app connects with the outside world, hackers and malicious parties can intercept and spy on each connection, exploit unprotected connections to steal data, compromise the app, and destroy the user experience and your brand. Preventing MitM attacks is a very important part of ensuring secure connections and delivering a layered security defense. In fact, OWASP, a leading nonprofit foundation that works to improve the security of software, lists insecure communication as one of its OWASP Mobile Top 10 risks.

Appdome is a no-code mobile security and development platform that enables anybody to add a wide variety of security features, SDKs and APIs to Android and iOS applications. Using a simple ‘click to add’ user interface, anyone can use mobile client certificates in any app in seconds, no-code or coding required.

This Knowledge Base article describes how to pin mobile client certificates to a mobile app so that only trusted, valid mobile apps can connect to protected resources/servers. This protects the backend servers and infrastructure against connections originating from compromised endpoints or malicious bots.

How to Use Mobile Client Certificates to Ensure Only Valid Apps can Connect to Servers

Mobile Client Certificates – Using Appdome’s no-code mobile app security platform, you can ensure that only validated apps can connect to backend servers. This is done by pinning (embedding) the certificate and private key to the mobile app so that only trusted, validated mobile apps can connect to protected resources/servers. This protects the backend servers and infrastructure against connections originating from compromised endpoints or malicious bots. It enables the app to present a unique client-side certificate as part of the initial TLS connection to its server (provided that the server is configured to distribute digital certificates via SCEP or similar protocol).

4 Easy Steps to Use Mobile Client Certificates in Android & iOS apps

Please follow these 3 easy steps to add Mobile Client Certificates to any iOS and Android app using Appdome.

  1. Upload an Android or iOS App to Appdome’s no code security platform (.apk, .aab, or .ipa)
  2. In the Build Tab, under Security, expand Secure Communication, switch ON Mobile Client Certificates
  3. Upload client’s private certificate and key (client P12/PKCS) for authentication.
  4. Click Build My App
