How to Validate Session Fingerprint (TTL) with Appdome's MobileBOT™ Defense Using AI

Last updated July 13, 2026 by Appdome

This Knowledge Base article describes how to use Appdome’s AI in your CI/CD pipeline to continuously deliver plugins that Validate Session Fingerprint (TTL) in Mobile apps.

What is Session Fingerprint (TTL)?

Session Fingerprint (TTL) is a unique, one-time token generated during session initiation or at key transaction points in mobile applications. Its primary function is to prevent replay attacks, where intercepted requests are duplicated by malicious actors. Replay attacks often occur during man-in-the-middle (MitM) scenarios or through automated bot activities, where attackers attempt to re-use valid requests to gain unauthorized access or privileges. The Session Fingerprint (TTL) ensures that each session or transaction is assigned a one-time identifier, making it impossible for attackers to replicate legitimate requests without detection, thus maintaining the integrity of communications between the app and server. Without the Session Fingerprint (TTL), attackers could more easily manipulate session data, exposing apps to significant security risks, including data breaches, unauthorized financial transactions, and violation of data privacy laws.

How Appdome Protects Mobile Apps with Session Fingerprint (TTL)

Appdome’s MobileBOT™ Defense integrates Session Fingerprint (TTL) validation into its Anti-Bot Payload mechanism, ensuring secure, one-time token generation during critical points in the app’s operation. When the Session Fingerprint (TTL) is generated, it is securely transmitted to the server, where it is validated. If any attempt to replay or reuse the token is detected, Appdome invalidates the session and prevents further communication. This process not only stops replay attacks but also enhances the overall security framework by ensuring that each session remains unique and valid, thus preventing unauthorized access and maintaining the app’s integrity.

Prerequisites for Using Appdome's Session Fingerprint (TTL) Plugins:

To use Appdome’s mobile app security build system to Validate Session Fingerprint (TTL) , you’ll need:

Appdome account (create a free Appdome account here)
A license for Session Fingerprint (TTL)
Mobile App (.ipa for iOS, or .apk or .aab for Android)
Signing Credentials (see Signing Secure Android apps and Signing Secure iOS apps)

How to Implement Validate Session Fingerprint (TTL) in Mobile Apps Using Appdome

On Appdome, follow these simple steps to create self-defending Mobile Apps that Validate Session Fingerprint (TTL) without an SDK or gateway:

Designate the Mobile App to be protected.
1. Upload an app via the Appdome Mobile Defense platform GUI or via Appdome’s DEV-API or CI/CD Plugins.
2. Mobile App Formats: .ipa for iOS, or .apk or .aab for Android
3. Session Fingerprint (TTL) is compatible with: Obj-C, Java, JS, C#, C++, Swift, Kotlin, Flutter, React Native, Unity, Xamarin, and more.
Select the defense: Session Fingerprint (TTL).

Create and name the Fusion Set (security template) that will contain the Session Fingerprint (TTL) feature as shown below:

Figure 1: Fusion Set that will contain the Session Fingerprint (TTL) feature

Follow the steps in Sections 2.2-2.2.2 of this article to add the Session Fingerprint (TTL) feature to your Fusion Set via the Appdome Console.

When you enable API Protection you'll notice that the Fusion Set you created in step 2.1 now bears the icon of the protection category that contains Session Fingerprint (TTL).

Figure 2: Fusion Set that displays the newly added Session Fingerprint (TTL) protection
Note: Annotating the Fusion Set to identify the protection(s) selected is optional only (not mandatory).

Open the Fusion Set Detail Summary by clicking the “...” symbol on the far-right corner of the Fusion Set. Copy the Fusion Set ID from the Fusion Set Detail Summary (as shown below):

Figure 3: Fusion Set Detail Summary

Follow the instructions below to use the Fusion Set ID inside any standard mobile DevOps or CI/CD toolkit like Bitrise, Jenkins, Travis, Team City, Circle CI or other system:

Refer to the Appdome API Reference Guide for API building instructions.

Look for sample APIs in Appdome’s GitHub Repository.

Add the Session Fingerprint (TTL) feature to your security template.

Navigate to Build > API & Bot Protection tab > MobileBOT™ Defense section in the Appdome Console.
Like all other options in ONEShield™, Session Fingerprint (TTL) is turned on by default, as shown below:
Figure 4: Selecting Session Fingerprint (TTL)
Note: The App Compromise Notification contains an easy to follow default remediation path for the mobile app end user. You can customize this message as required to achieve brand specific support, workflow or other messaging.

Toggle On API Protection > Session Fingerprint (TTL).
Note: The checkmark feature Session Fingerprint (TTL) is enabled by default, as shown below.

Figure 4: Selecting Validate Session Fingerprint (TTL)

Initiate the build command either by clicking Build My App at the bottom of the Build Workflow (shown in Figure 4) or via your CI/CD as described in Section 2.1.4.

Congratulations! The Session Fingerprint (TTL) protection is now added to the mobile app

Certify the Session Fingerprint (TTL) feature in Mobile Apps

After building Session Fingerprint (TTL), Appdome generates a Certified Secure™ certificate to guarantee that the Session Fingerprint (TTL) protection has been added and is protecting the app. To verify that the Session Fingerprint (TTL) protection has been added to the mobile app, locate the protection in the Certified Secure™ certificate as shown below:

Figure 5: Certified Secure™ certificate

Each Certified Secure™ certificate provides DevOps and DevSecOps organizations the entire workflow summary, audit trail of each build, and proof of protection that Session Fingerprint (TTL) has been added to each Mobile app. Certified Secure provides instant and in-line DevSecOps compliance certification that Session Fingerprint (TTL) and other mobile app security features are in each build of the mobile app.

Using Threat-Events™ for Session Fingerprint (TTL) Intelligence and Control in Mobile Apps

Appdome Threat-Events™ provides consumable in-app mobile app attack intelligence and defense control when Session Fingerprint (TTL) is detected. To consume and use Threat-Events™ for Session Fingerprint (TTL) in Mobile Apps, use AddObserverForName in Notification Center, and the code samples for Threat-Events™ for Session Fingerprint (TTL) shown below.
