Device Intelligence

Know every device. Trust every session.

One stable identity per device — even when cookies clear, apps reinstall, and users log out. Recognize returning visitors, score risk, bind accounts, and stitch sessions — from one fingerprint, in under 200ms.

What it does

An identity layer. And a risk layer.

Device Intelligence does two jobs from one fingerprint: it gives every device a durable identity, and it scores that device's risk in real time. Multiple capabilities, one SDK.

01 · Identity Recognize

Know a returning device — even when it's logged out.

One persistent Device ID survives cleared cookies, reinstalls, and factory resets. Recognize churned users in milliseconds and skip cold-start onboarding.

still recognized
02 · Risk Score

Score the risk behind every session.

Device, app, network, and behavioral signals collapse into a real-time risk verdict — emulators, tampered apps, remote-access tools, spoofed GPS, keyloggers, and more.

emulator→remote-access
high risk · block
03 · Identity Bind

Map the device-to-account graph.

Link a device to every account it touches, and an account to its trusted devices. Surface multi-accounting, promo abuse, and fraud rings at a glance.

The blind spot

Auth tells you who. Not what they're on.

Once an attacker has the OTP — via phishing, SIM-swap, or social engineering — authentication has already said yes. The device is the only thing left that can catch them.

What we detect

Signals across categories.

Every request is silently inspected across device, app, network, location, and session context — on Android and iOS, with zero added user steps.

Act on it — no code

Turn signals into policy.

Configure rules in the dashboard. Each fires on a signal or score threshold, takes an action, and shows your own message. No backend logic to ship.

AllowSession proceeds normally.
WarnProceeds, but the user sees a message.
RestrictCertain features are blocked, with a message.
BlockSession is denied entirely.
Example policy
if device risk > 70 or blacklisted
"This device can't be verified right now."
Block
if remote access and high-value transfer
"End your screen-share session to continue."
Block
if VPN or proxy detected
"Please disconnect your VPN before using this app."
Restrict
if debugger attached
"Disconnect the debugger before continuing."

Device as identity

One device, its whole history.

A persistent Device ID ties every session, account, and reset back to the same handset — powering both fraud-ring detection and frictionless returning-user experiences.

Persistent Device ID
Survives reinstalls, factory resets, and logouts — with a confidence score.
Returning-user recognition & anonymous login
Recognize churned users instantly, or let the device be the identity and convert to a full account later — history intact.
Device-bound sessions
Refuse stolen or replayed tokens that reappear on a different handset — silently, with no UX change.
Connected devices & sharing limits
Ship a "manage devices" screen and enforce concurrent-stream or device-per-account limits per plan.
Who it's for

Built for any app where the device is the battleground.

Account takeover Fake signups & bots Multi-accounting Device farms Social engineering Credential stuffing

BFSI — banks, NBFCs, wallets, trading

They fight: ATO, mule accounts, transaction fraud, and social-engineering scams.

Step-up per workflow — login, password reset, add payee, high-value transfer.
Link mule networks — many accounts ↔ one device via the persistent Device ID.
Stop remote-assisted scams — on-call + remote access + mirrored screen.
Fewer false positives for returning users on trusted devices.
The wedge

Why teams pick OTPless.

Auth-native
The only device intelligence that lives inside your auth layer — not a second SDK to ship and reconcile.
Social-engineering chain
On-call + remote access + mirrored screen, detected together — the signal no competitor catches all at once.
Malware layer
Harmful apps, keyloggers, and accessibility-service abuse — caught on the device, in real time.
GPS + IP cross-referencing
Impossible-travel detection that catches spoofing single-source location checks miss.
Identity linking & persistent ID
A Device ID that survives resets and reinstalls, plus account-graph linking to expose rings.
Built-in rules engine
Allow, warn, restrict, or block — with custom user-facing messages, configured with zero code.
One SDK

Ships in the SDK you already have.

Device Intelligence rides inside the same OTPless SDK as Smart Auth and SNA — no separate install. Signals are collected during the auth flow and returned alongside the auth result.

No new SDK — one integration covers auth and intelligence.
Silent collection — signals gathered during the existing flow, zero added UX.
Risk on the response — read the verdict server-side and branch your own logic.
