Which payment app is most secure?

Security in payment apps largely depends on features like strong authentication, including 4-6 digit UPI PINs and biometric login options such as fingerprint or facial recognition. Apps like Paytm offer enhanced protections such as a dedicated Security Shield, which locks the application, and features that prevent screen recording during UPI payments, adding critical layers of protection against fraud. Using secure networks and official app stores is also essential for maximizing safety.
