Core Capabilities of the Global Source Platform

Resolving Access Challenges with Marriott Global Source

⚠️ Forgotten Password

Cause: User cannot recall their login password for Marriott Global Source or Mhub.

Solution: If you've forgotten your password, navigate to the login page and look for a Password Reset or Forgot Password link. You'll typically need to enter your username, and instructions will be sent to the email address associated with your account. For employees, if this doesn't work, contact your manager or internal HR support.

⚠️ Access Denied or Incorrect Credentials

Cause: The system does not recognize your username or password, or you lack proper authorization.

Solution: Double-check your username and password for typos. Remember, your Bonvoy account details will not work here. If you're an employee, ensure your credentials are correct as provided by your HR or IT department. If you are a corporate client or franchisee, confirm your access through your Travel Management Company or Marriott sales representative.

⚠️ Difficulty Locating Support or Training

Cause: Users find the support structure for Global Source fragmented or training materials hard to access.

Solution: Official training resources can be limited and sometimes gated behind login walls. For corporate clients, Marriott offers webinars and documentation. Property owners might receive on-site training. If you're encountering issues, contacting your regional sales representatives or specific internal support channels is often recommended. Employees should consult their managers or HR for guidance on internal support resources.
