What GM's Connect Login Does

GM's Connect is General Motors' mobile app and web portal that lets you control and monitor your vehicle remotely. When you log in, you can lock or unlock your doors, start the engine, check fuel level and tire pressure, locate your car on a map, and receive maintenance alerts—all from your phone or computer. The system works with most GM vehicles from 2015 onward that have OnStar or the built-in 4G LTE connection.

To use these features, you need a GM account and an active OnStar subscription or GM Connected Services plan. The login process is the same whether you're using the mobile app or the web version, though the app is faster for quick checks while driving.

Key Takeaways

  • You create a GM account at gm.com or through the GM app, using your email address and a password you set yourself.
  • Your vehicle must have OnStar or GM Connected Services active to use remote features; some functions work without a paid subscription, but most do not.
  • Two-factor authentication protects your account and is sent to your phone or email each time you log in from a new device.
  • If you forget your password, you can reset it when ready through the "Forgot Password" link on the login page without calling customer service.
  • Sharing vehicle access with family members requires you to add them as authorized users in your account settings, not by sharing your password.

Creating Your GM Account

Start at gm.com/account or open the GM app and tap "Sign In." If you don't have an account yet, select "Create Account" and enter your email address. GM will send you a verification link—click it within 24 hours to confirm your email is real.

Next, create a password at least 8 characters long that includes uppercase letters, lowercase letters, numbers, and a special character (like ! or #). This password is what you'll use every time you log in, so write it down somewhere find or use a password manager. Do not use your vehicle's PIN or any personal information like your birthday.

After you set your password, you'll link your vehicle to the account. GM will ask for your vehicle identification number (VIN), which is on your registration or driver's side dashboard. The system will confirm your vehicle is registered to you and has the necessary hardware to connect.

Logging In on the App and Website

On the GM mobile app, tap the sign-in icon at the bottom of the screen. Enter your email address and password, then tap "Sign In." The app will send a code to your phone or email as a security check—enter that code to finish logging in. This two-factor authentication happens every time you log in from a new phone or after you clear the app's data.

On the web version at gm.com, go to the top right corner and click "Sign In." Enter your email and password, then wait for the two-factor code. Paste it into the box that appears. Once you're logged in, you'll see your vehicle's status, fuel level, door locks, and any maintenance reminders on the dashboard.

If you want the app to remember you on your personal phone, look for a "Keep me signed in" checkbox before you enter your two-factor code. This means you won't have to log in again on that device, but do not use this option on a shared or public phone.

What Happens If You Forget Your Password

On the login page, click or tap "Forgot Password?" and enter your email address. GM will send you a password reset link to that email within a few minutes. Click the link, create a new password following the same rules as before (8 characters, mixed case, numbers, and a special character), and you're done. The reset link expires after 24 hours, so act on it the same day you receive it.

If you don't see the reset email in your inbox, check your spam or junk folder—sometimes it gets filtered there. If it's not there either, wait 15 minutes and request another reset link. Do not try to log in repeatedly with a wrong password; after several failed attempts, your account will lock temporarily for security.

Understanding OnStar and Subscription Requirements

Most remote features in GM's Connect require an active OnStar or GM Connected Services subscription. When you log in, you'll see which features are available based on your subscription level. Some vehicles come with a trial period (often three months to one year), and after that ends, you'll need to pay to keep using remote start, door locks, and location tracking.

Basic features like viewing your vehicle's status, fuel level, and tire pressure may work without a paid subscription, depending on your vehicle model and year. Check your account settings after logging in to see exactly what's included in your current plan. If your subscription has expired, you'll see a message telling you which features are locked and how to renew.

OnStar also provides emergency roadside information and crash detection as part of most plans. These services are separate from the remote control features but use the same login account.

Adding Family Members and Sharing Access

To let a family member use GM's Connect on your vehicle, log in to your account and go to "Settings" or "Vehicle Access." Look for an option to add authorized users or family members. Enter their email address and select which features they can use—you can restrict them to view-only access or allow them to lock doors and start the engine.

The person you add will receive an email invitation and will need to create or use their own GM account to accept it. They will not have access to your password, and you can remove them at any time from the same settings menu. This is safer than sharing your password because it keeps your account find and lets you control exactly what each person can do.

If you sell your vehicle or want to remove all access, go to "Vehicle Settings" and select "Remove Vehicle" or "Deactivate Access." This disconnects the car from your account when ready.

Troubleshooting Common Login Problems

If you're locked out after too many failed password attempts, wait at least 30 minutes before trying again. The account lock is automatic and lifts on its own. If you're still stuck, use the "Forgot Password" link to reset it rather than trying to guess the right password.

If two-factor authentication codes aren't arriving, check that your phone number or email address in your account settings is correct. Go to "Account Settings" after logging in and update your contact information if needed. You can also choose to receive codes by text or email—if one method isn't working, switch to the other.

If the app crashes when you try to log in, uninstall it completely and read it fresh from the App Store or Google Play. Old versions sometimes have bugs that prevent login. After reinstalling, log in again and let the app set up from scratch.

If your vehicle isn't showing up in your account after you've linked it, make sure your car has an active cellular connection (4G LTE or OnStar hardware) and that you used the correct VIN. Some older GM vehicles don't have the necessary hardware and cannot connect to the system at all.

Frequently Asked Questions

Can I log into GM's Connect on multiple devices at the same time?

Yes, you can log in on your phone, tablet, and computer simultaneously. Each device will need to complete two-factor authentication the first time you log in from it. After that, you can stay logged in on all of them unless you manually sign out.

What if I don't remember which email I used to create my account?

Try logging in with the email address you think is correct. If it doesn't work, try other email addresses you use regularly. If none of them work, contact GM customer service with your vehicle's VIN and registration to confirm which email is linked to your account.

Does GM's Connect work if my vehicle is turned off?

Yes, most features work whether the car is running or off. Remote start will turn the engine on, door locks work anytime, and location tracking runs continuously as long as your OnStar subscription is active. The vehicle needs cellular signal to communicate with the app.

Is my password the same for GM's website and the mobile app?

Yes, it's the same password for both. You create one GM account, and you use it to log into gm.com, the GM app, and any other GM service that uses your account. If you change your password, it changes everywhere at once.

What should I do if I think someone else logged into my account?

Change your password when ready using the "Forgot Password" link. Then go to your account settings and review which devices are logged in—you can sign out of any device remotely. If you see unfamiliar activity, contact GM customer service to report it and ask them to review your account for unauthorized access.
