TL;DR: Embedded finance is pushing mobile apps into the regulated financial perimeter, where third-party SDKs, APIs, token handling, and runtime tampering now shape fraud and breach risk, according to Guardsquare. For IAM and security teams, the key issue is not app UX but whether identity, attestation, and secrets controls can still prove trust at the mobile layer.

By the numbers:
- Embedded finance is projected to reach $7.2 trillion in transaction volume by 2030.
- More than 70% of digital commerce now takes place on smartphones.
Questions worth separating out
Q: How should security teams protect embedded finance apps from runtime tampering?
A: Security teams should assume the app can be altered after install and design controls for execution time, not only build time.
Q: Why do mobile finance apps need stronger trust controls than ordinary consumer apps?
A: Because they increasingly initiate regulated actions such as payments, credit decisions, and wallet transfers.
Q: What do security teams get wrong about mobile and application secrets?
A: They often treat embedded secrets as implementation details instead of reusable access.
Practitioner guidance
- Treat mobile apps as regulated financial endpoints Map every embedded payment, credit, or wallet flow to a control owner, a trust check, and a revocation path before it reaches production.
- Protect secrets with hardware-backed storage and rotation Move sensitive keys and tokens out of app code, store them in hardware-backed keystores where possible, and enforce rotation on a defined lifecycle.
- Bind backend access to attested app sessions Require attestation before granting API access and tie the token to a specific session so modified or cloned apps cannot reuse trust indefinitely.

Mobile financial apps are becoming regulated identity and trust endpoints, not just user interfaces. Embedded finance pushes sensitive decisions into the app layer, where tokens, attestation, device posture, and runtime integrity all influence whether a transaction should be trusted. That widens the identity governance boundary beyond IAM login events and into session assurance, app integrity, and secret handling. Practitioners should treat the mobile client as part of the identity control plane.
A question worth separating out:
Q: Who is accountable when an embedded finance app is cloned or tampered with?
A: Accountability usually spans product security, application engineering, IAM, and fraud operations because each function owns part of the trust chain. The right model assigns clear ownership for attestation, secret management, runtime protection, and transaction monitoring. If those controls are split across silos, no team can see the full failure path.
