A server comprises a communications module; a processor coupled with the communications module; and a memory coupled to the processor and storing processor-executable instructions which, when executed by the processor, configure the processor to authenticate a user via a first authentication channel; receive, via the communications module and from a computing device associated with the user, a signal representing a request to transfer a first quantity of resources; determine that the first quantity of resources is less than a first threshold associated with the first authentication channel; obtain identity data associated with the request to transfer the first quantity of resources; determine, based on the identity data, that a request to transfer a second quantity of resources has been previously initiated by the user via a second authentication channel that is different than the first authentication channel; and determine that the sum of the first quantity of resources and the second quantity of resources is less than the first threshold, and in response to determining that the sum of the first quantity of resources and the second quantity of resources is less than the first threshold, initiate the transfer of the first quantity of resources.
