Marketplaces
Protect embedded finance, payouts and loyalty capabilities without replacing the underlying authentication platform.
The challenge
Marketplaces accumulate value that behaves like money — stored balances, seller payouts, embedded wallets, loyalty points — while still needing sign-up and checkout to stay frictionless for both buyers and sellers. Adding stronger verification everywhere would slow onboarding and conversion; adding it nowhere leaves the exact features attackers target unprotected.
Because these platforms often run on an existing identity provider with limited appetite for change, new controls need to sit on top of that stack rather than replace it, and need to be adjustable by fraud or product teams as new abuse patterns emerge across a fast-growing, multi-sided user base.
Key use cases
Seller onboarding and sign-up
Passkeys and adaptive MFA are introduced at account creation to improve completion rates while establishing a stronger authentication baseline from day one, rather than retrofitting it after a seller base has already grown around weaker credentials.
Payout and balance protection
Adaptive challenges are scoped specifically to payout destination changes, balance withdrawals and other high-value actions, using no-code rules so fraud teams can tighten or relax conditions as new abuse patterns appear across the seller base.
Account takeover defence
Phishing-resistant passkeys and behavioural risk signals reduce the effectiveness of credential stuffing against buyer and seller accounts, which is a common route into embedded wallets and stored balances on marketplace platforms.
Fraud protection across buyer and seller flows
Risk-based MFA is applied differently depending on the value and sensitivity of the action being taken, so casual browsing and listing remain untouched while payout, dispute and account-recovery flows carry stronger verification.
Reducing SMS dependency at scale
High sign-up and login volumes make SMS OTP costly to sustain; shifting appropriate flows to WhatsApp OTP and passkeys lowers messaging spend while improving delivery reliability in markets with variable SMS performance.
Core capabilities
Adaptive MFA
Challenges scaled to the specific action being taken, rather than applied uniformly across every login.
Passkeys alongside existing login methods
Introduced without removing existing options, so buyers and sellers can adopt them at their own pace.
No-code rules per segment
Policies can differ by user type, capability or account tenure without a separate application build.
User observability
A consolidated view of authentication events and outcomes supports fraud investigation across the platform.
Pre-built UI and SDKs
Drop-in components speed integration into existing buyer and seller-facing applications.
First payout to a new bank account
A seller adds a new payout destination shortly after account creation. Left unchecked, this is one of the more common precursors to payout fraud on marketplace platforms. A rule configured specifically for this event requires a step-up challenge — a passkey or push approval — before the change is accepted, and the platform applies a short cooling period before the first payout to that destination is released. Meanwhile, the seller can continue listing items, messaging buyers and managing orders without any additional friction, because the rule is scoped narrowly to the payout-destination event rather than applied across the account as a whole.
- 1Seller adds a new payout destination
- 2Step-up challenge required before the change is accepted
- 3Short cooling period applied before first payout release
Expected outcomes
- Fewer successful takeovers of buyer and seller accounts
- Payout fraud attempts caught before funds are released
- Onboarding and everyday browsing remain low-friction
- Fraud policy adjusted per segment without new application releases
- Reduced SMS messaging costs at high sign-up and login volumes
How CyberLane helps
CyberLane helps marketplace operators map where financial value actually sits within the platform — payouts, wallets, loyalty balances — and design step-up rules that target those points precisely. We advise on architecture and workflow design across buyer and seller journeys, build the business case for phased rollout, and plan a proof of concept before coordinating implementation with Authsignal or a qualified delivery partner.
- Mapping of high-value actions across buyer and seller journeys
- Step-up rule design for payout and balance events
- Segmented rollout plan by user type or capability
- Proof-of-concept scoping against existing identity provider
- Implementation oversight through go-live
CyberLane is independent and works on the decision rather than the deployment. Product-specific delivery is coordinated with the vendor or a qualified implementation partner.
