Managing your health should not feel hard. Many people forget appointments, lose test results, or wait on hold just to ask a simple question. A patient portal can fix a lot of that. This guide explains how to sign up for and log in to Patient Gateway, the online portal used by Mass General Brigham. It also covers common problems and how to solve them.
What Is Patient Gateway?
Patient Gateway is the secure online portal for patients of Mass General Brigham. This health system includes Massachusetts General Hospital, Brigham and Women’s Hospital, and other participating hospitals and practices. The portal gives you a private way to connect with your care team.
With a Patient Gateway account, you can usually:
- Send secure messages to your doctor’s office
- View test results and visit notes
- Request prescription refills
- Ask for or manage appointments
- Update some personal details
You can use it on a computer or through a phone app. This is helpful if you are busy, if you live far from the clinic, or if you simply prefer to handle things online.
One important point: Patient Gateway is a service from your health system. Always use the official website and the official app. Never enter your login details on a page that came from a strange email or text.
Who Can Use Patient Gateway?
Patient Gateway is for patients of participating Mass General Brigham hospitals and practices. If you have been seen by one of these providers, you may be able to create an account.
There are a few rules worth knowing:
- Adults can sign up online.
- Patients under 18 cannot sign up online. A parent or guardian should call the Help Desk or the doctor’s office to ask about access on behalf of a child. The official site lists the Help Desk number as 800-745-9683.
- Family helpers can sometimes get “proxy access.” We explain this later in the article.
Before You Start: What You Need
Getting ready first makes sign-up faster. Try to have these things with you:
- A working email address
- A mobile phone number
- Your date of birth
- Your home address and basic personal details
- An activation code, if you received one
An activation code is a short code given to you at a visit. You may see it on your after-visit summary or on an enrollment letter. If you do not have one, do not worry. You can still sign up by using the self sign-up option, which is explained below.
5 .Easy Steps to Sign Up and Log In
Step 1: Go to the Official Patient Gateway Website
Open your web browser and go to the official Mass General Brigham Patient Gateway site: patientgateway.massgeneralbrigham.org. You can also download the official app from the Apple App Store or Google Play Store.
Check the web address carefully before you type anything. A safe habit is to type the address yourself or use the link from your hospital’s own website, not a link from an unknown message.
On the home page, you will see options to sign in or to enroll. If you already have an account, skip ahead to Step 5. If you are new, continue with Step 2.
Step 2: Choose Sign Up
Click the Sign Up or Enroll button. You now have two paths:
Path A: You have an activation code.
Enter the code exactly as it appears on your paper or summary. Then follow the instructions on the screen.
Path B: You do not have an activation code.
Choose the self sign-up option. You will enter your personal information, and the system will use a few questions to confirm that you are really you.
Step 3: Verify Who You Are
Your health information is private, so the portal needs to be sure the right person is signing up. There are two common parts to this step.
First, you enter your personal information and confirm your contact details. This is how the system knows how to reach you.
Second, if you use self sign-up, you will answer identity questions. The official site says these questions come from a third-party verification system. The questions are usually based on your personal history, so read them carefully and answer slowly.
The official site also warns that processing and verification can sometimes take up to a week after you submit a request. If your account does not appear right away, do not panic. Give it a little time, and contact the Help Desk if you are still waiting after that.
Step 4: Create Your Username and Password
Once you are verified, you can create your login details. This is the part where many people make mistakes, so take your time.
For your username:
- Pick something you will remember.
- Avoid using your full birth date or other private details.
For your password:
- Make it long and hard to guess.
- Mix letters, numbers, and symbols.
- Do not reuse a password from your email or bank.
A password manager can help you store passwords safely. Write down your username and keep it somewhere private. Many “I’m locked out” problems start with a forgotten username.
Step 5: Log In
Now you are ready. Go back to the Patient Gateway home page or open the app.
- Enter your username.
- Enter your password.
- Click Sign In.
For extra safety, you may be asked for a security code, especially if you sign in from a new device. If this happens, check your phone or email for the code and enter it on the screen.
Once you are in, take a few minutes to look around. Check your contact information, review your message settings, and see where your test results and appointments appear.
Using the Mobile App
Many people prefer to use Patient Gateway on a phone. The app can be easier for quick tasks, like reading a message or checking an appointment.
Here are a few simple tips:
- Download the app only from the official app store.
- Keep your phone’s software updated.
- Use a screen lock on your phone.
- Log out if you share your device with others.
Common Login Problems and Easy Fixes
Even careful users run into trouble sometimes. Here are the most common problems and what to try.
“I forgot my username.”
Look for a Forgot Username link on the login page. Follow the steps and give the information the system asks for. If you still cannot find it, try searching your email for messages from the portal. You may have received your username there when you first signed up.
“I forgot my password.”
Use the Forgot Password link on the sign-in page. You will be asked to confirm who you are. After that, you can make a new password. If you often struggle with online account problems, our How To guides have simple step-by-step help for many everyday tech tasks.
“My password does not work.”
Passwords are usually case sensitive, so check for these common mistakes:
- Caps Lock is turned on
- An extra space at the beginning or end
- Typing the wrong username
- Using an old password
If you tried a few times and it still fails, reset your password rather than guessing again and again.
“My activation code is not working.”
Activation codes can expire, and they are easy to mistype. Check each letter and number. If it still fails, ask your doctor’s office for a new code, or use the self sign-up option instead.
“I did not receive my security code.”
Wait a minute and check your spam or junk folder. Make sure your phone has a signal. Also confirm that the phone number or email on your account is correct. If your contact details are old, you may need to update them through the Help Desk or your doctor’s office.
“The website will not load.”
Try these quick fixes:
- Refresh the page.
- Try a different browser.
- Clear your browser cache and cookies.
- Turn off pop-up blockers for the site.
- Try again on your phone or another device.
“My account is locked.”
Too many wrong attempts can lock an account for safety. Wait a little while, then try a password reset. If that does not work, contact support.
How to Get Help
If you have tried the simple fixes and still cannot get in, ask for help. You have a few options.
Call the Help Desk. The official sign-up page lists 800-745-9683 for questions. Phone numbers can change, so always check the official website for the latest number.
Read the FAQ. The official site has a Frequently Asked Questions page that covers technical issues, such as forgotten usernames and passwords.
Talk to your doctor’s office. Staff can often help with activation codes, contact details, and access for children. You can ask at your next visit or call the front desk.
Before you call, have this information ready:
- Your full name and date of birth
- The email address or phone number on your account
- A short description of the problem
- Any error message you saw
This helps the support team solve your issue faster.

Proxy Access: Helping a Family Member
Sometimes you need to help someone you care for, such as a child or an older parent. Many portals allow this through proxy access. This means a trusted person gets permission to view some information or send messages for the patient.
Rules about proxy access can be strict because they protect privacy. For example, patients under 18 cannot sign up online, and a parent or guardian must contact the Help Desk or the child’s doctor to ask about access. For adults, the patient usually needs to give permission first.
Never use another person’s login without permission. If you are a caregiver, ask the care team how to set up proper access.
Staying Safe While Using Patient Gateway
Your medical information is sensitive. A few simple habits keep it safer.
Use the official site only. Scammers sometimes send fake emails or texts that look like they come from a hospital. Do not click links from messages you did not expect. Go straight to the official website instead. If you want to learn how to spot a trustworthy site, read our guide on how to judge a website’s content and trustworthiness.
Never share your password. Real support staff will not ask you for your full password.
Use a private connection. Avoid logging in on public Wi-Fi when you can. If you must, keep sessions short and log out afterward.
Log out on shared devices. This is important on library, work, or family computers.
Watch your account. If you see messages or activity that you do not recognize, change your password and tell the Help Desk.
Tips for Getting the Most From Patient Gateway
Once you are signed in, a few good habits will save you time.
- Check messages often. Your care team may send updates, reminders, or questions.
- Keep your contact information current. This helps with security codes and reminders.
- Write clear messages. Keep them short and put your main question first.
- Remember it is not for emergencies. If you have a serious problem, call your local emergency number or go to the nearest emergency room. Do not wait for a portal reply.
- Prepare for visits. Review past notes and write down questions before you see your doctor.
Is Patient Gateway Free?
Access to the portal is generally offered to registered patients as a service from the health system, with no sign-up fee. Check the official site or ask the Help Desk if you have questions about billing features or other services.
