  Key Concepts: 
  Proof of Possession (PoP) is a security feature in SAP BC-SEC Security that requires users to prove they have possession of a specific device or token before they can access certain data or applications. This is done by entering a one-time password (OTP) that is generated by the device or token. The OTP is only valid for a limited amount of time and must be entered within that time frame in order to gain access.
  
  How to use it: 
  In order to use PoP, users must first register their device or token with the system. Once registered, they will be able to generate an OTP when they need to access certain data or applications. The OTP must then be entered into the system within the allotted time frame in order to gain access.
  
  Tips & Tricks: 
  It is important to remember that the OTP generated by the device or token is only valid for a limited amount of time, so it is important to enter it quickly in order to gain access. Additionally, it is important to keep the device or token secure and not share it with anyone else in order to maintain security.
