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):

// The shared secret for direct access to booking is in auth.php
//$shared_secret = "X****" ;

// Credential for email account sending invoices is in auth.php
//$invoice_imap = "x****" ;
//$invoice_folder = "x****" ;
//$invoice_user = "x****" ;
//$invoice_psw = "x****" ;

// OVH credentials for (in auth.php)
//$finances_smtp_user = 'x****@spa****ation.be' ;
//$finances_smtp_password = 'x****' ;

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

Sincerely,
Emma
