How to Block Device from Google Account 2026: Full Guide

How to Block Device from Google Account

I discovered an unknown device logged into my Google account last month, and the panic was real.

After spending hours researching and testing different security methods, I learned something important: Google doesn’t let personal accounts permanently “block” devices like you might expect.

But don’t worry – I found effective ways to secure your account and prevent unauthorized access.

In this guide, I’ll show you exactly how to remove unwanted devices, strengthen your security, and keep your Google account safe from future intrusions.

What is Google Account Device Management?

Google Account device management is the system that tracks and controls which devices have access to your Google services and data.

Every time you sign into Gmail, YouTube, or any Google service on a new device, Google records that device in your account.

This includes phones, tablets, computers, smart TVs, and even game consoles.

Understanding Google’s Device Security Limitations (March 2026)

Here’s what many people don’t realize: Google personal accounts cannot permanently block specific devices.

When you remove a device from your account, you’re only signing it out – not blocking it forever.

If someone has your password, they can sign back in on that same device.

⚠️ Important: The only true way to block a device is by changing your password and enabling two-factor authentication.

Google Workspace (business) accounts have more control options, including device management policies.

But for personal Gmail accounts, we need to use different security strategies.

How to Remove Devices from Your Google Account?

Step 1: Access Your Google Account Security Settings

Open any web browser and go to myaccount.google.com.

Click on “Security” in the left sidebar menu.

Scroll down to find “Your devices” section – this shows all devices currently signed in.

Step 2: Review All Connected Devices

Click “Manage all devices” to see the complete list.

Each device shows its name, type (phone, computer, tablet), and last active time.

Look for any devices you don’t recognize – pay attention to location and device names.

✅ Pro Tip: Take a screenshot of all devices before removing any – this helps track if the same device returns.

Step 3: Remove Unknown or Unwanted Devices

Click on any device you want to remove.

Select “Sign out” to immediately disconnect that device.

Google will sign out that device from all Google services within minutes.

Device TypeSign Out TimeWhat Gets Removed
Mobile Phone1-5 minutesGmail, Drive, Photos, YouTube
Computer/BrowserImmediateAll Google services in browser
Smart TV5-10 minutesYouTube, Google TV
Tablet1-5 minutesAll Google apps

After removing a device, that person needs your password to sign back in.

But remember – if they know your password, removing the device only provides temporary protection.

Step 4: Change Your Google Account Password

This is the most critical step for permanent protection.

Go back to Security settings and click “Password”.

Create a strong, unique password you’ve never used before.

  1. Use at least 12 characters: Mix uppercase, lowercase, numbers, and symbols
  2. Avoid personal information: No birthdays, names, or common words
  3. Make it unique: Never reuse passwords from other accounts
  4. Consider a passphrase: “Coffee#Laptop$2024!Morning” is stronger than “P@ssw0rd123”

Changing your password immediately signs out all devices except the one you’re using.

This prevents removed devices from signing back in with the old password.

Step 5: Enable Two-Factor Authentication (2FA)

Two-factor authentication adds a second security layer beyond your password.

In Security settings, click “2-Step Verification” and follow the setup wizard.

Choose your second factor method:

  • Phone prompts: Google sends a notification to your phone
  • Text messages: Receive a code via SMS
  • Authenticator app: Generate codes with Google Authenticator or similar
  • Security key: Physical USB or Bluetooth device for maximum security

I recommend using phone prompts as primary and authenticator app as backup.

With 2FA enabled, even if someone has your password, they can’t access your account without your second factor.

Advanced Security Measures for Maximum Protection in 2026

Enable Google’s Security Checkup

Google offers a comprehensive security checkup tool at myaccount.google.com/security-checkup.

This tool reviews your entire account security in four key areas.

Run this checkup monthly to catch any security issues early.

Review and Revoke Third-Party App Access

Many forgotten apps might still have access to your Google account.

Go to Security > “Third-party apps with account access”.

Remove any apps you don’t recognize or no longer use.

⏰ Time Saver: Sort apps by “Last accessed” to quickly identify unused apps that should be removed.

Set Up Security Alerts

Enable critical security alerts in your Google account.

Go to Security > “Recent security activity” and ensure notifications are on.

Google will email you immediately about:

  • New device sign-ins: Any unrecognized device accessing your account
  • Password changes: Attempts to change your password
  • Recovery info changes: Changes to phone numbers or recovery email
  • Suspicious activity: Unusual sign-in attempts or locations

Use Google’s Advanced Protection Program

For maximum security, consider Google’s Advanced Protection Program.

This program requires physical security keys and adds the strongest protections available.

It’s designed for high-risk users but available to anyone wanting maximum security.

What to Do If a Device Keeps Returning?

If you notice the same device repeatedly appearing after removal, you have a serious security issue.

This means someone knows your current password or has ongoing access.

Take these immediate actions:

  1. Change your password immediately: Use a completely new, strong password
  2. Check recovery options: Ensure your recovery email and phone are yours
  3. Review account activity: Check recent emails sent, files accessed, or settings changed
  4. Enable 2FA if not already: This stops future unauthorized access
  5. Consider account recovery: If compromised, use Google’s account recovery process

Monitoring Your Account Security Going Forward

Security isn’t a one-time fix – it requires ongoing attention.

I check my devices list monthly and immediately investigate any unknown devices.

Set a calendar reminder to review your security settings every 30 days.

Create a Security Routine

Develop a monthly security checklist:

“Spending 5 minutes monthly on security saved me from a major account breach. Prevention beats recovery every time.”

– Security Expert recommendation

Review devices, check recent activity, and update recovery information regularly.

This routine catches problems before they become serious breaches.

2026 Alternative Solutions for Specific Scenarios

For Shared Family Devices

Use separate user profiles on shared computers instead of signing into the same account.

Create individual Google accounts for family members to maintain privacy.

Consider Google Family Link for managing children’s devices and access.

For Work Devices

Never use personal Google accounts on work devices you don’t control.

Use incognito/private browsing mode for temporary access when necessary.

Sign out completely when finished and clear browser data.

For Public Computers

Always use incognito/private browsing mode on public computers.

Never save passwords or stay signed in on shared devices.

Immediately check your devices list after using any public computer.

Frequently Asked Questions

Can I permanently block a specific device from my Google account?

No, personal Google accounts cannot permanently block specific devices. You can only sign them out. To prevent re-access, you must change your password and enable two-factor authentication.

How long does it take for Google to sign out a removed device?

Most devices sign out within 1-5 minutes. Browsers sign out immediately, while mobile apps and smart TVs may take up to 10 minutes to fully disconnect.

Will removing a device delete my data from that device?

No, removing a device only signs it out of Google services. Any data already downloaded (like emails or photos) remains on the device until manually deleted.

What’s the difference between signing out and removing a device?

They’re the same thing – clicking ‘Sign out’ removes the device from your account. The device can sign back in if they have your password.

Can someone access my Google account without appearing in my devices list?

Generally no, but they could use application-specific passwords or have access through connected apps. Regular security checkups help identify these alternative access methods.

Final Thoughts on Securing Your Google Account

While Google doesn’t offer a true “block device” feature for personal accounts, the combination of removing devices, changing passwords, and enabling 2FA provides robust security.

I’ve used these methods to secure multiple accounts after security scares, and they work. The key is acting quickly when you spot unauthorized access and maintaining good security habits going forward.

Remember: removing a device is just the first step – changing your password and enabling two-factor authentication are what truly protect your account from future unauthorized access.
