what makes tru.ID unique
How does tru.ID work?

Like magic.

tru.ID provides the same authentication experience as a network itself - no need to login, and it's secure and seamless.

developer first

SIM security, now an API

Until tru.ID, network authentication was only available to operators themselves, or enterprise. Now, tru.ID offers an API platform, supported by guides and tutorials.

Possession factor using SIM security

tru.ID leverages the cryptographic security of the SIM card to verify the user’s mobile number, a pairing that is unique. We call this pairing SIM-based authentication.

connects real-time to mobile network authentication

Connected to mobile networks

tru.ID partners with global Mobile Network Operators to provide real-time access to the same SIM-based authentication used to bill and connect mobile customers.

Connects to mobile networks in real-time

tru.ID’s partners with global mobile network operators to provide access to their authentication systems. If your business uses the mobile phone number as a credential – be it as part of registration, or access login, tru.ID looks up the number, matches it to the network, and asks – is this a valid subscriber? If the network replies ‘yes’, tru.ID returns a positive response. It's a URL-based lookup with no personal data exchanged.

Seamless SIM-based authentication

tru.ID verifies the user’s mobile number with the SIM card identity, a pairing that is unique and near impossible to copy or tamper with. We call this pairing SIM-based authentication. There’s nothing more the user needs to do than enter their mobile phone number, which is checked against the network's SIM authentication using a URL-based lookup over a data connection.

tru.ID developer flow

A developer-first global API platform

Until tru.ID, access to network-level authentication systems was only available to the mobile operators themselves, or to enterprise customers. tru.ID changed all that and built a developer-first API platform. Integrate once, then scale as you expand, be it nationally or globally, supported by comprehensive guides and tutorials for Android, iOS, ReactNative, and Web.

Adding tru.ID is easy

Discover why forward-thinking companies are upgrading to silent SIM-based authentication.


Authentication, reimagined

The password is an anachronism, SMS OTP is open to fraud, auth apps are cumbersome, and hardware is expensive. It's time to build a new standard of identity and access management - SIM-based MFA.
