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):

      expected_mailbox = {
        host: 'imap.gmail.com',
        port: 993,
        ssl: true,
        start_tls: false,
        email: 'gitlab-inc****g@gmail.com',
        password: '[RE****ED]',
        name: 'inbox',
        idle_timeout: 60,
        delete_after_delivery: true,
        expunge_deleted: true
      }
      expected_options = {

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

Sincerely,
Emma
