Billy was a computer genius. He loved solving puzzles and figuring out how things worked. One day, his friend Lucy asked him if he could help her unlock her diary. "I forgot the password," she said. Billy smiled mischievously and said, "A password isn’t enough to stop me. I can hack that easily."

Billy sat down in front of Lucy's computer and started typing furiously. Lines of code flashed across the screen as he worked his magic. Within minutes, the diary's password was cracked and the pages unlocked. Lucy couldn't believe her eyes!

As Billy was about to close the diary, Lucy asked, "But isn't hacking wrong?" Billy paused for a moment and replied, "Hacking can be used for good too. I only hacked your diary to show you that passwords alone aren't always secure." Lucy nodded, starting to understand.

Billy continued, "Sometimes, people use simple passwords that are easy to guess. It's important to create strong passwords that are hard for hackers to crack." Lucy realized that she needed to be more careful with her passwords in the future.

Billy and Lucy spent the rest of the day talking about computer security. Billy showed Lucy how to create a strong password using a combination of letters, numbers, and symbols. Lucy was amazed at how much she didn't know about keeping her information safe.

From that day on, Lucy always made sure to use strong passwords for all her accounts. She even taught her family and friends about the importance of computer security. Billy had opened her eyes to a whole new world of knowledge.
