Which is the most secure UPI app?

All UPI payment apps adhere to security guidelines set by NPCI and RBI, ensuring safe digital transactions. These measures include strong application-level security, PIN protection, encryption, OTP verification, and fraud monitoring. Paytm, for instance, offers advanced in-app protections like the Security Shield feature and biometric login options to further enhance transaction security. Users should always follow best practices, such as creating a strong UPI PIN and avoiding public Wi-Fi.
