Only the expected user's device with the corresponding phone number & SIM can complete the verification flow.
Able to easily authenticate a returning user, or run silent step-up checks for higher risk activities and transactions.
A SIM verified phone number along with SIM age is at par with MFA through possession factors such as YubiKeys.
Forget forgotten passwords and help users access their accounts using their secure mobile number.
Whether shared, stolen, or guessed, passwords (including OTPs) are the biggest threat to user security.
Although secure, biometrics such as facial scans are expensive and not accessible to all.
Hardware possession factors like USB keys are both costly to deploy at scale and hated by users — far from ideal.
The humble SIM card has the same cryptographic security as chip & PIN credit cards.
Users can be either silently authenticated, or approve a login request on an app, or scan a QR code with their phone.
Unlike card readers or USB keys, SIM-based verification requires no investment into hardware for users so you can secure every last one.
Your users already have their SIM possession factor. All your app needs is tru.ID magic to make use of it — with or without an app.
