Mobile Connect enables convenient and secure authentication and identity verification for online services through mobile networks. It uses factors such as something the user has (their mobile phone and SIM card) and something they know (PIN or pattern) for multi-factor authentication without separate hardware tokens. Over 2.5 billion users globally can access the service, which supports a range of identity services including authentication, authorization, attribute sharing, and fraud prevention. Mobile network operators are well-positioned to provide these services due to their experience managing networks and user identity securely and privately.
