  Key Concepts: 
  Callback mode is a security feature in SAP BC-SEC-USR User Administration that requires users to enter a code sent to their registered mobile phone or email address in order to access the system. This code is known as a one-time password (OTP) and is used to verify the user's identity.
  
  How to use it: 
  To enable callback mode, users must first register their mobile phone or email address with the system. Once this is done, they will be prompted to enter the OTP code each time they log in. The OTP code will be sent to their registered device and must be entered within a certain time frame in order for the user to gain access.
  
  Tips & Tricks: 
  It is important to keep your registered device secure and up-to-date in order to ensure that you are able to receive the OTP codes when needed. Additionally, it is recommended that you use a unique password for each system you access, as this will help protect your data from unauthorized access.
