The Frontier Beyond OTPs: Why Mobile App Security Doesn’t End at Login?

January 28, 2026 3 Min read

For years, static passwords, dynamic One-time Passwords (OTPs), and Multi-factor Authentication (MFA) have been the trusted gatekeepers of digital identity. But today, they are no longer enough. Modern fraudsters do not bother attacking the front door anymore, they exploit what is inside the house.

Post-authentication fraud is rising at an alarming pace across mobile-first industries like BFSI, fintech, and digital commerce. Fraudsters bypass identity checks altogether by compromising runtime environments, targeting APIs, or exploiting device vulnerabilities, often without ever touching credentials.

The biggest misconception in mobile app security today is: If the login is secure, the app is secure. That couldn’t be further from the truth!

The Real Problem: Attacks Do Not Stop at Login

1. Runtime Blind Spots:
Once users log in, most apps assume the environment is safe. It is not.

  • Malware, repackaged apps, and overlay attacks exploit runtime weaknesses.
  • Fraudsters hijack active sessions and execute transactions from within.

2. Compromised Devices:
A secure app on a rooted or jailbroken device is vulnerable.

  • Malicious keyboard overlays, screen sharing, and unsafe environments open hidden backdoors.

3. Unsecured APIs:
Many fraudsters bypass the UI entirely.

  • Weak APIs are prime targets for token replay, man-in-the-middle exploits, and automated fraud.

Result: Fraud happens after successful authentication – where most defences do not exist.

AppProtectt Approach: Defence Built Inside the App

AppProtectt, Protectt.ai’s AI-native Mobile App Security Platform, is purpose-built to stop threats & fraud in real time by embedding protection directly within the app.

It ensures continuous defence across every session, every device, and every transaction.

1. Embed Protection with Runtime Application Self-Protection (RASP)

  • AppProtectt integrates Runtime Application Self-Protection (RASP) to detect and block malicious activity as it happens.
  • It prevents tampering, reverse engineering, overlay attacks, and session hijacking in real time.
  • Unlike static perimeter defences, AppProtectt’s RASP safeguards every user interaction, no matter the device, OS, or network. It transforms your app from a passive target into an active shield.

2. Enforce Continuous Device Integrity

  • Validate the trustworthiness of the device at every step.
  • Detect rooted or jailbroken devices, malicious tools, or unsafe conditions.
  • Apply adaptive responses – restrict high-risk functions or block sensitive actions entirely.

Never trust the device blindly. Verify continuously with AppProtectt.

Authentication Is Just the Start

Login protection is necessary, but no longer sufficient. AppProtectt extends security beyond authentication – across runtime and device layers – delivering a holistic shield against evolving mobile threats.

True mobile app security is layered:

  • RASP for real-time in-app defence,
  • Device integrity for trusted environments.

Fraudsters have evolved. Thus, security must be built inside, not just around. The challenge is no longer just about the OTP; it is also about what happens after the OTP is validated. For mobile-first industries like BFSI, fintech, and digital commerce, the security of their business empires depends entirely on this strategic shift. Authentication starts the journey; RASP ensures protection every step of the way.
