Better mobile device binding

The only phishing-resistant mobile device binding solution. Confirm that the SIM card in a device belongs to the phone number you expect, before you bind the corresponding identity to an app install.

Using a SIM card as a possession factor

Real-time device checking

tru.ID APIs use the same technology as mobile networks to definitively confirm an active SIM card and the associated mobile phone number, in real time.

Smooth user experience

Users don't have to send or receive any messages, or perform any other action besides providing their phone number, which is verified in a few seconds.

Only real mobile identities

Unlike SMS-based device binding which relies on shared credentials, tru.ID filters out virtual or burner numbers so only real mobile users can sign up — no bots or spamsters.

Deterministic, not probabilistic

Device binding through fingerprinting either the browser or the device is just guesswork. When you need to be certain, tru.ID gives you a yes/no result and zero false positives.

Legacy alternatives are a misfit for device binding

Compromised security

Many tradeoffs

Shared credentials are susceptible to MITM and social engineering, while authenticators are disconnected from identity.

Compliance is a challenge

Tougher every day

Whether it's the Reserve Bank of India, the UK's FCA guidelines for SCA, or the EU's PSD2 rules, officials are focusing on mobile security.

Conversion challenges

A usability challenge

Implementing strong customer authentication with legacy MFA methods leads to drop-offs in conversion.

Device binding through SIM-verified mobile numbers

Powerful security

Powerful security

The strong cryptographic security of a SIM card affords the same Level of Assurance as dedicated USB keys.

streamline

Effortless UX

Users can either receive a push notification to approve login requests through an authenticator app, or scan a QR code with their phone.

money

Low cost

Unlike card readers or USB keys, SIM-based verification requires no investment into hardware for your users.

Ready to deploy

Your users already have their SIM possession factor. All you need is tru.ID magic — with or without an authenticator app.
