# OTAC Solutions | PoC of PLC user

SSenStone’s Programmable Logic Controller OTAC provides a highly optimised and highly secure authentication solution specifically for PLC devices. It utilises our dynamic 'one-time authentication code' (OTAC) technology to resolve typical ICS/OT security challenges. 

OTAC ensures only known and authorised users/devices can access PLC using dynamic, non-reusable, constantly changing code guaranteed with 0% duplicates (defeats packet sniffing attacks)

 •  Password sharing in password-only authentication systems  
 •  Difficulty managing ID/PW specified for each PLC device  
 •  Difficulty managing user changes (leavers / contractors etc)  
 •  Hacking attempts using password cracking software
