Building secure login processes can protect your customers against account takeovers and prevent SIM swapped numbers from access accounts — all without interrupting login flows. With Twilio Lookup, your business can connect with carrier APIs to lookup identity signals — like SIM data and carrier infrastructure — to signal whether to continue with authentication or add more blockers. Twilio Verify can instantly decide if a valid SIM number, device, and user name are being used in any login, allowing legitimate users to access their account seamlessly.
If a user’s identity signals do seem suspicious, your business can quickly identify fake or fraudulent users so you can swoop in to apply extra step-up security as needed. For example, you might ask a suspicious individual to verify their identity again using a face scan or fingerprint before they can access their payment information, change their password, or view sensitive information. This can help mitigate account takeover and keep your legitimate users’ personal information safe.
