Security-related question about a possible exposed credential

[Emma-NYL]

Hello,

My name is Emma, I am conducting an academic study on possible credential exposure in public GitHub repositories.

While analyzing this repository, I found a string that may represent a credential. I'm including the code snippet below containing possible leakage. To avoid exposing sensitive information publicly, I marked the sensitive information.

Could you please help clarify whether the detected string is:

1. a real credential, or
2. a placeholder / example value?

Thank you for your time.

Code snippet (sensitive values masked):

// Replace the next variables with your credentials
const char* ssid = "yo****sid";
const char* password = "your****sword";
const char* host = "your_m****server";
const int   port = 8883;

Thank you in advance for your time - I really appreciate it!

Sincerely,
Emma
