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):

/***************************
 * Begin Settings
 **************************/
// WIFI
const char* WIFI_SSID = ".****"; 
const char* WIFI_PWD = ".****";

// Setup
const int UPDATE_INTERVAL_SECS = 10 * 60; // Update every 10 minutes

// Display Settings
const int I2C_DISPLAY_ADDRESS = 0x3c;

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

Sincerely,
Emma
