Method for providing an enhanced level of authentication related to a secure software client application that is provided, by an application distribution entity, in order to be transmitted, using a telecommunications network, to a client computing device in view of software code of the software client application being executed by the client computing device, wherein a first secure communication channel is established - in view of transmitting an instance of the software client application to the client computing device - between the client computing device and the application distribution entity, wherein the client computing device comprises an instance of an authentication provider functionality, wherein a second secure communication channel is established between the authentication provider functionality and an authentication provider server entity, and wherein a third secure communication channel is established between the authentication provider server entity and a third party server entity, wherein the method comprises the following steps: -- in a first step, in view of subsequently allowing for an authenticated transmission of data - provided by the software client application instance upon it being executed by the client computing device - to the third party server entity, the authentication provider functionality is initialized or installed within the client computing device and the second secure communication channel as well as the third secure communication channel is initialized or established, -- in a second step, prior to, during or subsequent to the first step, the software client application instance is transmitted, using the first secure communication channel, to the client computing device, -- in a third step, subsequent to the second step, a fourth secure communication channel is established, between the software client application instance and the third party server entity, by means of exchanging at least parts of cryptographic key information and/or security token information using - besides the second secure communication channel and the third secure communication channel - an internal secure communication channel, the internal secure communication channel being internal to the client computing device, between the software client application instance and the authentication provider functionality. wherein a first secure communication channel is established -
