What remote access does and why you might want it
Remote access lets another person see and control your computer from their own device — usually to help you fix a problem, install software, or walk you through a task. When you turn it on, you give permission for that person to move your mouse, type on your keyboard, and see everything on your screen in real time, as if they were sitting at your desk.
The most common reason to turn on remote access is to let a trusted friend, family member, or technician troubleshoot something without being physically present. If your computer is running slowly, a tech-savvy relative can log in and see what's happening. If you need help setting up a program, someone can show you step by step. You stay in control — you can see what they're doing, stop the session whenever you want, and they cannot access your computer unless you explicitly allow it each time.
Remote access is different from letting someone borrow your password. When you use the built-in remote tools on Windows or Mac, the other person cannot log in on their own. You initiate the connection, you can watch it happen, and you can end it when ready. This matters because it means you are not handing over your login credentials or leaving a back door open.
Key Takeaways
- Windows and Mac both have free built-in remote access tools — Quick information on Windows and Screen Sharing on Mac — that work without installing anything extra.
- You must start the remote session yourself and stay present while it happens; the other person cannot connect without your permission each time.
- Before you turn on remote access, make sure you trust the person and understand what they will be doing on your computer.
- Remote access works best when both people have a stable internet connection and can talk on the phone or video call at the same time.
- You can end a remote session when ready by closing the window or unplugging your internet, and the other person loses access when ready.
Turning on remote access in Windows using Quick information
Windows includes a tool called Quick information that is already on your computer. To start a remote session, open the Start menu (the Windows logo in the bottom left), type "Quick information" into the search box, and press Enter. The Quick information window will open.
Click the button that says "Give information" — this is the option you use when you want to let someone else control your computer. Windows will generate a security code that looks like a string of numbers and letters. This code is unique to this session only and expires after ten minutes if the other person does not use it. Read the code aloud to the person you want to help you, or type it into a text message or email. They will enter that code on their end, and once they do, you will see a prompt asking you to confirm that you want to let them in. Click "Share" to allow the connection.
Once they are connected, they can see your screen and move your mouse and keyboard as if they were using your computer. You can see everything they do. If you want to stop the session at any time, close the Quick information window or press the Escape key. The connection ends when ready and they lose access.
Turning on remote access on a Mac using Screen Sharing
Mac computers have a built-in feature called Screen Sharing that works similarly to Quick information. To turn it on, click the Apple menu in the top left corner, select "System Settings" (or "System Preferences" on older Macs), then look for "General" in the sidebar. Click "Sharing" — you may need to scroll down to find it.
In the Sharing window, look for "Remote Management" or "Screen Sharing" in the list on the left. Click the checkbox next to it to turn it on. Mac will ask you to confirm and may ask for your password. Once it is on, you will see a message that tells you the address other people can use to connect to your Mac — it usually looks like "username@192.168.x.x" or a similar format.
Give this address to the person who will be helping you. They will open their own Screen Sharing tool (on another Mac) or use a compatible app (on Windows or another device), enter your address, and request a connection. You will see a prompt on your screen asking whether you want to allow them in. Click "Allow" to let them take control. Like Quick information, you can end the session by closing the window, and the connection stops when ready.
What to do before you turn on remote access
Before you let someone control your computer, close any windows or browser tabs that contain sensitive information — bank logins, medical records, passwords, or personal documents you do not want them to see. They will be able to see your entire screen, so take a moment to minimize or close anything private.
Make sure you know exactly what the other person is going to do. If they say they need to "look at your system," ask them to be specific: Are they checking what programs are running? Installing a driver? Changing a setting? The more specific they are, the easier it is for you to watch and make sure nothing unexpected happens. If someone asks to turn on remote access but cannot explain what they need to do, that is a sign to say no.
Have your phone or a video call ready so you can talk to the person while they are connected. Remote access works much better when you can ask questions in real time and they can explain what they are seeing. If they are a family member or friend, a quick phone call before you start makes the whole process smoother.
When remote access does not work and what to try instead
Remote access requires both computers to have a working internet connection. If your internet is down or very slow, the connection may drop or be too laggy to use. If that happens, you have a few other options. You can ask the person to walk you through the steps over the phone or video call while you do the work yourself. You can take a screenshot of the problem, email it to them, and ask for information. Or, if the issue is urgent and you cannot fix it remotely, you can take your computer to a local repair shop and let a technician look at it in person.
Some workplaces and schools block remote access tools for security reasons. If you are on a work or school network and Quick information or Screen Sharing is not working, check with your IT department before trying to turn it on — they may have their own remote support tool they want you to use instead.
Keeping yourself safe when using remote access
Remote access is safe when you use it with someone you trust and you stay in control of the session. The biggest risk is letting someone you do not know take control of your computer. Never turn on remote access for a stranger, even if they call you and say they are from your bank, your internet provider, or a software company. Real companies do not call you out of the blue and ask for remote access to your computer.
If someone you do not know contacts you and asks for remote access, hang up or close the message. If they are persistent, you can report the call to the Federal Trade Commission at reportfraud.ftc.gov. Scammers use fake remote access requests to steal passwords, install malware, or trick people into sending money.
When you are done with a remote session, make sure the other person has actually disconnected. Close the remote access window on your end. If you are worried they might try to reconnect, you can turn off the remote access feature entirely — go back into Quick information or Screen Sharing settings and toggle it off. This ensures no one can connect unless you turn it back on.
Frequently Asked Questions
Can someone use remote access if I am not at my computer?
No. With Quick information and Screen Sharing, you must be present and approve the connection. The other person cannot connect on their own or without your permission. If you step away from your computer while they are connected, they can still see and control it, but they cannot initiate a new session without you.
What if I accidentally close the remote access window?
The connection ends when ready. The other person will see that they have been disconnected and cannot do anything on your computer anymore. You can start a new session by opening Quick information or Screen Sharing again and generating a new code or address.
Can I use remote access on my phone or tablet?
Quick information and Screen Sharing are designed for computers. However, you can read third-party apps like TeamViewer or AnyDesk on phones and tablets if you need remote support on a mobile device. These apps work similarly — you start the session and give permission before the other person can connect.
Is remote access the same as letting someone use my password?
No. Remote access is safer because the other person does not need your password. You control when the session starts and stops, and they cannot log in on their own. Sharing your password means they could access your computer anytime, even when you are not there, and you would not know what they were doing.
What happens if my internet cuts out during a remote session?
The connection drops when ready and the other person loses access. When your internet comes back, they cannot reconnect unless you start a new session and give them a new code or address. You will need to initiate the connection again from the beginning.
