Prove has extended its SIM-based silent authentication technology to Wi-Fi connections and mobile web sessions, allowing supported authentication flows to verify possession of a mobile device without requiring a direct cellular data connection or an SMS one-time passcode.
The capability uses carrier-backed cryptographic signals associated with the device’s SIM. Traditional silent network authentication has depended on the phone communicating over a cellular connection, creating a limitation when customers use Wi-Fi or enter a service through a mobile browser.
Prove says its new approach removes that connection requirement for supported journeys. The authentication occurs in the background, providing a device-possession check without asking the user to retrieve and type a code from a text message.
The feature is part of Prove Unified Authentication, which selects an authentication method according to the interaction and can escalate to additional checks when greater assurance is needed. The SIM-based signal establishes possession of the device within that process; other identity and risk controls can be applied through the wider workflow.
Prove is also adding the capability to its Pre-Fill service, which uses verified information to populate fields during customer onboarding. The company says combining device authentication with that process can reduce the number of separate steps customers encounter while entering a new service.
The release extends the company’s identity platform for people, businesses and AI agents. That platform brought authentication and fraud controls together with device-key management and services intended to maintain a verified customer relationship when phones or other account details change.
Prove has also integrated identity verification into Ownera’s FinP2P tokenized-asset network. That arrangement supports institutional participants that need to verify counterparties and reuse identity information across transactions. The Wi-Fi extension concerns the mobile authentication channel used to establish a device-possession signal.
Synchrony’s senior vice president and head of authentication, Luis Da Silva, said the company looks forward to working with Prove to leverage the expanded capability. Prove says it handles more than 10 billion authentications annually across its services.
Chief product officer Ori Snir said the expansion is intended to keep authentication available across everyday changes in connectivity, including account access from a train or a coffee shop and purchases made over a store’s Wi-Fi. The added coverage lets Prove apply the SIM-based possession signal through more of those customer interactions.
