TeamViewer Unattended Access Not Working: Root Causes and Ways to Fix Them

We analyzed TeamViewer users’ feedback on various online forums to identify the root causes of these issues. We have also discussed some actionable solutions to troubleshoot these issues.

Key Takeaways:

  • • You need to configure Easy Access properly to maximize the benefits of this great feature.
  • • The random password settings option can interfere with unattended access, so disable it. 
  • • Installing TeamViewer Host allows you to enjoy uninterrupted access to TeamViewer. 
  • • The firewall and network settings can interfere with TeamViewer and thus require necessary changes.

Now let’s explore the root causes of the TeamViewer unattended access not working issue in detail and how to fix them one by one.

As long as your device is linked to your TeamViewer account, you should be able to connect without entering a password.

1. Not Configuring Easy Access Properly

Easy Access is a useful feature that lets you connect to devices remotely. However, it requires that the remote device is properly assigned to your TeamViewer account and that the correct settings are enabled. This issue is often discussed in detail in TeamViewer’s Knowledge Base, which explains how to properly link your device to your TeamViewer account.

How to Fix This Issue

Follow the steps below to correctly set up Easy Access and assign the remote device:

  1. On your remote device, log in to your TeamViewer account using your credentials.

  2. Go to: Settings (⚙️) > General > Account Assignment

    settings Easy Access

  3. Choose Assign to Account. Check and make sure the device is linked to your TeamViewer account.

    Assign to Account Security settings

  4. Look under Security. Enable Easy Access.

  5. Try making the connection after making these configuration changes.

2. Random Password Settings Causing Password Prompts Despite Enabling Easy Access

Many users have witnessed that TeamViewer prompts them to enter a password while establishing remote connections even after they have enabled the Easy Access feature. TeamViewer unattended access asking for password frustrates users and makes them question the credibility of this feature. 

In numerous Reddit threads, users have discussed that random password settings could be the reason behind this malfunction. These settings might interfere with how Easy Access functions, prompting users to enter the password due to security concerns. 

How to Fix This Issue

To fix the issue of unnecessary password prompting on TeamViewer, follow these steps:

  1. On the remote device, launch TeamViewer.

  2. Go to: Settings (⚙️) > Advanced settings > Security

  3. Locate Random password (for spontaneous access). It’s the second option in Security. Expand the menu to find Disabled (no random password). Click it.

    No Random password

  4. Save the changes by clicking OK.

  5. Once you disable the Random password option, TeamViewer should not ask for your password while making remote connections. This means you can fully benefit from Easy Access.

3. Software Updates Interfering With the Interface

Long-time users of TeamViewer often find the new interface confusing, especially when setting up unattended access with the Easy Access feature. The design shift has raised concerns on forums like Spiceworks and Reddit. Many users have shared tips on reverting to the previous interface to reduce confusion.

How to Fix this Issue

Here are the steps to switch to the previous version or the classic TeamViewer interface:

    • • In the main menu, locate New Interface. Click on it to toggle it off or disable it. Once done, restart TeamViewer so that changes are reflected. Switch to the Classic Interface
    • • There’s an alternate way to switch to the interface if you can’t do it via the menu toggle. 
      • ❏ Open the settings by clicking the gear icon (⚙).
      • ❏ Go to the General tab and toggle off the Use new TeamViewer interface.

    Use new TeamViewer interface

4. Not Installing the TeamViewer Host

For seamless, always-on access, it’s important to install TeamViewer Host on remote devices. This version of TeamViewer is optimized for devices that need to remain accessible for unattended remote control. Insights into this common issue can be found in discussions on the TeamViewer Support Community, where users emphasize the importance of installing the correct version of the software.

How to Fix This Issue

  1. Download and install TeamViewer Host on your remote device.

  2. While installing the software, log in to your TeamViewer’s account with your credentials to assign the remote device properly.

  3. Activate Easy Access to eliminate password prompts every time you initiate a remote connection.

  4. Once installation is complete with the remote device properly assigned and Easy Access enabled, you should be able to use TeamViewer unattended access without interruptions. It will allow you to run remote sessions without interacting with the device manually.

5. Firewall or Network Restrictions

You may face issues connecting remotely to a device using TeamViewer in environments with strict firewall rules. The software can bypass many network restrictions. But some organizations or high-security networks may block its connections over security or data privacy concerns. 

On TeamViewer’s community, you can find users discussing this in the network configurations context. 

How to Fix This Issue

  1. Check Firewall and Network Settings: Ensure TCP/UDP port 5938 is open, or fallback ports 443 and 80 are allowed.

  2. Whitelist TeamViewer: Add *.teamviewer.com to your allowlist and ensure TLS 1.2 is enabled.

  3. Verify Network Access: Work with your IT department to ensure TeamViewer is not blocked on corporate networks or VPNs.

6. User Account Control (UAC) Restrictions

If TeamViewer is not running with administrative privileges, UAC prompts may block your ability to fully control the remote system, even during unattended sessions. To avoid these interruptions, TeamViewer should always run with elevated permissions.. 

How to Fix This Issue

Set TeamViewer to run as Administrator on your Windows computer:

  1. On your desktop or Start menu, find the TeamViewer shortcut icon. Right-click on it.

  2. Under the context menu, choose Properties.

  3. Go to Compatibility.

  4. Locate this option – Run this program as administrator and a box next to this option. Check the box.

  5. Click on Apply and then OK.

Apply this setting during deployment for managed devices. It will require you to adjust the deployment configuration. In an enterprise environment where you need to manage multiple systems, use Group Policy settings.

What’s the Importance of Unattended Remote Access?

Unattended access is a functionality useful for IT departments, remote workers, and businesses offering remote support to their customers. 

But if unattended access doesn’t work properly, it disrupts the workflow and increases operational costs. For example, IT administrators who work for managed service providers (MSPs) need to access customer machines 24/7 without end-user intervention. Failures with TeamViewer’s unattended access affects productivity and delay operations, adding up costs. 

Businesses need TeamViewer’s unattended access to work properly so their remote workers can efficiently fix IT issues and provide remote tech support.
