MahaSecure is an application that doesn't support PCs (Windows or Mac operating systems). MahaSecure can now be installed only on Android or iOS operating systems, which means that you need a portable device (phone, tablet) that has these operating systems.
If you have one, start the Play Store or App Store and search for MahaSecure. There is no need to configure it as it uses a username and password given to you by the bank. Once you log into the application, various services related to Internet Banking will be available.
