Disclosed are systems, methods, and computer-readable storage media for Bluetooth low energy (BLE) double authentication between a mobile device and server nodes. A system using BLE authentication can receive at a mobile device, an identifier of a dongle attached to a server that enables wireless communication and can establish a wireless low energy connection with the dongle without paring. The system can receive a server identifier and can determine whether the server has previously been authenticated to yield a determination. When the determination is that the server has not previously been authenticated, the system can receive a baseband management controller username and a password. When the determination is that the server has previously been authenticated, the system can determine whether to perform a double authentication to yield a second determination. The system can perform the double authentication when the second determination indicates that the double authentication should be performed.
