Hi Friend @razzor

Data tokenization is indeed a very useful method for protection of our personal or sensitive information. It also provides us a layer of enhanced security.

Although every method have some limitations but I think that its advantages are more then Its limitations. Providing the alphanumeric strings on the place of real data also prevent us from data breaches as well as from cyber attacks .

Overall you have explained all the questions very well. I wish you success in this Engagement Challenge.
