The security of computer files and folders has been a central issue since the arrival of windows. The passwords were then introduced to solve this problem but they themselves provide a number of disadvantages. In this article, we will study the disadvantages of passwords and how we can address them. A two-factor authentication system [T-FA] will also be proposed using Bluetooth as a factor along with the powerful Rijndael encryption algorithm. Bluetooth is the most commonly used technology for point-to-point short-range communication devices. In addition to being in common use, it also offers multiple connection. The Rijndael algorithm is an advanced encryption standard, believed to be the most effective cryptographic encryption and decryption algorithm. Its minimum of 10 encryption rounds and variable key size with a minimum of 128 bits makes it difficult to break. Coupled with the wide accessibility of Bluetooth and powerful encryption of Rijndael, you can create a two-factor authentication system [T-FA] that will not only erase the disadvantages of passwords but also create a friendly security system.
