The current paper is proposing a three-factor authentication (3FA) scheme based on three components. In the first component a token and a password will be generated (this module represents the kernel of the three-factor authentication scheme - 3FA). In the second component a pass-code will be generated, using to the token resulted in the first phase. We will use RSA for encryption and decryption of the generated values (token and pass-code). For the token ID and passcode the user will use his smartphone. The third component uses a searchable encryption scheme, whose purpose is to retrieve the documents of the user from the cloud server, based on a keyword and his/her fingerprint. The documents are stored encrypted on a mistrust server (cloud environment) and searchable encryption will help us to search specific information and to access those documents in an encrypted content. We will introduce also a software simulation developed in C\# 8.0 for our scheme and a source code analysis for the main algorithms.
