Steam Login Error Code E87
on Windows

Hi, I can't log in to Steam - I receive Error Code E87. I'm using the latest version of Windows 11.

Steam, the widely acclaimed digital distribution platform, offers users access to an extensive library of video games, community features, and more. However, Windows users may occasionally encounter the Steam Login Error Code E87, a frustrating obstacle that prevents access to their accounts and libraries. This error typically indicates a problem with the user's login credentials or network settings that Steam is unable to navigate through.

Error Code E87 often arises from issues related to network connectivity, corrupted Steam files, or outdated client software. It acts as a signal that Steam's attempt to connect to its servers and verify your login details has been thwarted. This can be due to various underlying causes, ranging from simple internet connection problems to more complex software conflicts within the Windows environment.

Addressing this error requires a systematic approach to identify and resolve the root cause. Here are several strategies users can employ:

• Verify internet connection. Ensure that your computer is connected to the internet and that the connection is stable. Try resetting your router or modem if necessary.
• Update Steam client. Running an outdated version of Steam can lead to compatibility issues. Check for and install any available updates to the Steam client.
• Clear Steam's download cache. Accumulated cache files can sometimes cause issues. Clearing the download cache through Steam's settings can resolve this.
• Run Steam as administrator. A lack of permissions can prevent Steam from operating correctly. Running the application as an administrator can circumvent these restrictions.
• Check Firewall and Antivirus Settings. Sometimes, firewall or antivirus settings might block Steam's access to the internet. Adjusting these settings to allow Steam can remedy the situation.
• Reinstall Steam: If all else fails, uninstalling and then reinstalling Steam can resolve underlying issues with the installation files.

Below you will find the instructions for these solutions, so try each of them until you find one that works for you and fixes Steam Login Error Code E87. If you would like to check your system for any underlying issues, we recommend employing a comprehensive PC repair app [d1].

Fix 1. Run network troubleshooter

First, make sure that your network connection is not causing this Steam error.

• Type Troubleshoot in Windows search and press Enter.

Fix 2. Check Steam's server status

Before exploring deeper troubleshooting methods, it’s essential to determine if the problem originates from Steam's servers. An outage on Steam's end means login attempts will fail, no matter the corrective actions taken locally. To assess the server status, consider using tools like Downdetector, visiting the dedicated Steam server status page, or checking Steam’s official Twitter account for updates on server-related issues.

Fix 3. Use Google's DNS

• Right-click on Start and select Settings.
• Go to Network and Internet section.
• Click on Change adapter options.
• Right-click on your internet connection and pick Properties.
• Select Internet Protocol Version 4 (TCP/IPv4) once and go to Properties or select Edit next to the DNS settings.
• Select Use the following DNS server addresses option and set your DNS to Google's:
  Preferred DNS server: 8.8.8.8
  Alternate DNS server: 8.8.4.4
• Click OK.

Fix 4. Run Steam as administrator

Running Steam as an administrator gives it additional permissions that may be required for certain actions, potentially resolving error E87.

• Right-click on the Steam shortcut or executable file.
• Select Run as administrator from the context menu.
• Log in to your Steam account and check if the error is resolved.

If the issue is fixed, you can set Steam to always run as admin as follows:

  Steam
  Steam Web Helper
