How Secure Is the App?
Security is a concern for many people — especially when real money is involved. The 9777 def app uses SSL encryption, which means every transaction you make is fully encrypted in transit. No one can intercept or steal that information.
Your account also supports two-factor authentication (2FA), meaning a password alone isn't enough to access your account — a one-time OTP sent to your mobile is required as well. Personal information and banking data are kept fully secure on separate servers.
