Configuring Remote TFS Access Credentials

How to Stop TFS from Asking for Your Password Every Time

Working with cloud-hosted Team Foundation Server from various locations? Stop the constant password prompts by configuring Windows Credential Manager for seamless authentication.

The Challenge

At 3Metas, we embraced cloud tools early in our development process. Team Foundation Server hosted on the internet provided our distributed team with centralized source control, work item tracking, and build management.

The Authentication Problem

When developers connect to remote TFS from their home networks or client sites, their local network credentials don't match the TFS server's domain. This forces TFS to display an authentication dialog every single time you interact with the server:

  • • Getting latest version
  • • Checking in changes
  • • Viewing work items
  • • Running builds

The Solution: Windows Credential Manager

Windows provides a built-in credentials vault that can store your TFS authentication, eliminating repetitive password prompts.

Step-by-Step Configuration

  1. Open Credential Manager

    Navigate to: Control Panel → User Accounts and Family Safety → Credential Manager

  2. Add Windows Credential

    Click "Add a Windows credential" (or "Add Windows Credentials" depending on your Windows version)

  3. Enter TFS Server Information

    Internet or network address:

    tfs.yourcompany.com

    Enter your TFS server's URL without http:// or https://

    User name:

    DOMAIN\username

    Use the domain\username format for TFS authentication

    Password:

    ••••••••••••

    Your TFS account password

  4. Save and Test

    Click OK to save. Next time you connect to TFS, Windows will automatically provide your credentials

Result

Visual Studio and other TFS clients will now authenticate automatically. No more interruption to your workflow every time you need to interact with source control!

Why This Works

Windows Credential Manager stores encrypted credentials that applications can access when needed. When Visual Studio attempts to connect to your TFS server, Windows automatically provides the stored credentials, creating a seamless single sign-on experience.

Additional Tips

Multiple TFS Servers

Working with multiple TFS instances? Add separate credentials for each server. Windows will automatically select the correct credentials based on the server you're accessing.

Updating Credentials

When your password changes, return to Credential Manager, select the TFS credential, click "Edit," and update the password. No need to delete and recreate.

Security Considerations

Credentials are encrypted using your Windows login. Ensure your workstation has:

  • • Strong Windows password
  • • Screen lock timeout enabled
  • • Full disk encryption on laptops

Alternative: Git Credential Manager

If you're using Git with Azure Repos (formerly TFS/VSTS), Microsoft provides the Git Credential Manager which offers similar functionality with additional features like multi-factor authentication support and personal access token management.

Cloud Development in 2010

In 2010, hosting development tools in the cloud was still relatively novel. Most companies ran TFS on-premises within their corporate network. At 3Metas, we saw the value early: our distributed team could work from anywhere with the same tools and processes, eliminating VPN complexity and enabling true location flexibility.

Modern Context

Note: This article from 2010 describes credential management for cloud-hosted TFS. Today, Azure DevOps (TFS's successor) uses Azure Active Directory for authentication, often with single sign-on and multi-factor authentication. However, the underlying principle remains: storing credentials securely to avoid repetitive authentication prompts. Modern tools like Git Credential Manager Core extend this concept with support for personal access tokens, OAuth, and conditional access policies. The Windows Credential Manager approach described here still works for legacy TFS instances and other Windows-integrated services.
