To reset the PostgreSQL password on a Windows system, follow these detailed steps to ensure a smooth process. This guide assumes you have administrative access to your PostgreSQL installation and the necessary permissions to modify user roles.
Step 1: Open the Command Prompt
Begin by launching the Command Prompt with administrative privileges. You can do this by searching for ‘cmd’ in the Start menu, right-clicking on ‘Command Prompt’, and selecting ‘Run as administrator’.
Step 2: Navigate to the PostgreSQL Bin Directory
Next, you need to navigate to the PostgreSQL bin directory where the psql command-line tool is located. This is typically found in the installation path, which might look something like this:
cd "C:\Program Files\PostgreSQL\13\bin"
Make sure to replace 13 with your actual PostgreSQL version number.
Step 3: Connect to PostgreSQL
Now, connect to your PostgreSQL database using the psql command. You will need to specify the username (usually postgres) and the database name (often postgres as well). Use the following command:
psql -U postgres -d postgres
If prompted, enter the current password for the postgres user.
Step 4: Reset the Password
Once you are connected to the PostgreSQL prompt, you can reset the password using the following SQL command. Replace <new_password> with your desired password:
ALTER USER postgres PASSWORD '<new_password>';
Make sure to choose a strong password that meets security guidelines, such as including upper and lower case letters, numbers, and special characters.
Step 5: Exit the PostgreSQL Prompt
After successfully changing the password, exit the PostgreSQL prompt by typing:
\q
Step 6: Restart PostgreSQL Service
To ensure that the changes take effect, restart the PostgreSQL service. You can do this from the Services management console:
- Press
Win + R, typeservices.msc, and hit Enter. - Locate the PostgreSQL service (it may be named
postgresql-x64-13or similar). - Right-click on the service and select ‘Restart’.
Conclusion
You have now successfully reset the PostgreSQL password on your Windows system. Remember to update any applications or services that connect to your PostgreSQL database with the new password to avoid connection issues. For more detailed information, refer to the official PostgreSQL documentation at PostgreSQL Documentation.
Introduction
Resetting the root (or superuser) password in PostgreSQL is a common task when you forget or need to change the password for security reasons. For Windows users, there are a few approaches you can take to reset the password. In this article, we will explore several solutions to reset the PostgreSQL root password on Windows.

Exit fullscreen mode
- After that, run PostgreSQL in single-user mode with this command:
postgres --single -D "C:\Program Files\PostgreSQL\16\data" postgres
Enter fullscreen mode
Exit fullscreen mode
-
Note: Replace
"C:\Program Files\PostgreSQL\16\data"with your actual data directory path if it’s different.
Step 3: Reset the Password
Once PostgreSQL starts in single-user mode, you’ll see a prompt where you can run SQL commands. To reset the password for the postgres user, use this command:
ALTER USER postgres WITH PASSWORD 'your_new_password';
Enter fullscreen mode
Exit fullscreen mode
- Replace
'your_new_password'with the new password you want to set.
After entering the command, press Enter to reset the password.
Step 4: Restart the PostgreSQL Service
After resetting the password, exit the single-user mode by closing the Command Prompt window. Then, go back to the Services tool:
- Right-click on PostgreSQL and choose Start to restart the service.
Step 5: Reconnect with pgAdmin
Finally, open pgAdmin 4 (or any other PostgreSQL client you use) and try connecting with the new password.
If it still doesn’t work, you may need to update the saved password:
- Right-click on the server in the Object Browser.
- Choose Properties → Connection.
- Enter the new password and click Save.
Simplified Process (For Quick Reference)
In simpler terms, here’s what you need to do:
- Stop PostgreSQL: Go to services.msc and stop PostgreSQL.
- Open Command Prompt as Admin: Search for cmd, right-click, and run as administrator.
- Navigate to PostgreSQL Folder: Use this command:
cd "C:\Program Files\PostgreSQL\16\bin"
Enter fullscreen mode
Exit fullscreen mode
- Run PostgreSQL in Single-User Mode:
postgres --single -D "C:\Program Files\PostgreSQL\16\data" postgres
Enter fullscreen mode
Exit fullscreen mode
- Reset the Password:
ALTER USER postgres WITH PASSWORD 'your_new_password';
Enter fullscreen mode
Exit fullscreen mode
- Restart PostgreSQL: Go back to Services and start PostgreSQL again.
- Reconnect with pgAdmin: Use the new password to connect.
Final Thoughts
I hope this guide makes it easy for you to reset your PostgreSQL password on Windows using single-user mode. It’s a lifesaver when you’re locked out of your database.

When working with PostgreSQL databases, we may occasionally forget the PostgreSQL administrator password or need to change it. In such cases, it’s crucial to know the correct process to reset the password. Resetting the PostgreSQL password is essential for ensuring the security of our database system while restoring access.
In this guide, we will provide a detailed, step-by-step process to reset PostgreSQL user password, modify the authentication method in the pg_hba.conf file, and restore our system to its default authentication setup. Follow these steps to update PostgreSQL password securely and get back to managing our database with ease.
Understanding the PostgreSQL Authentication System
PostgreSQL uses the pg_hba.conf file to manage host-based authentication, determining how users can connect to the database system. The pg_hba.conf file is typically located in the data directory of our PostgreSQL installation (for example, C:\Program Files\PostgreSQL\12\data on Windows). The hba in pg_hba.conf stands for host-based authentication, which allows us to control user access and authentication methods.
When the password is forgotten, we can modify the authentication method to allow login without a password. Here’s how we can reset the password for the postgres user and return to the correct configuration.
Step-by-Step Process to Reset the PostgreSQL User Password
Follow the below steps to reset a password for the postgres user:
Step 1: Backup the pg_hba.conf File
Before making any changes, it’s a best practice to create a backup of the pg_hba.conf file. This ensures that we can restore the original file later. We can either copy the file to another directory or simply rename it for backup purposes. For example, we can rename it as pg_hba.conf.bk.
Step 2: Modify the pg_hba.conf File for Passwordless Login
Now, we need to modify the pg_hba.conf file to allow connections without requiring a password. This step temporarily changes the authentication method from md5 (password authentication) to trust (passwordless authentication). Locate the following section in the pg_hba.conf file:
# TYPE DATABASE USER ADDRESS METHOD# IPv4 local connections:
host all all 127.0.0.1/32 trust# IPv6 local connections:
host all all ::1/128 trust# Allow replication connections from localhost, by a user with the
# replication privilege.host replication all 127.0.0.1/32 trust
host replication all ::1/128 trust
Step 3: Restart PostgreSQL Server
After modifying the authentication method, the PostgreSQL server needs to be restarted to apply the changes. On a Windows machine, we can restart the PostgreSQL service from the Services panel. Alternatively, we can restart the server directly using the following command in the Windows terminal:
pg_ctl -D "C:\Program Files\PostgreSQL\12\data" restart
The “C:\Program Files\PostgreSQL\12\data” is the data directory. Ensure that we replace "C:\Program Files\PostgreSQL\12\data" with the correct path to our PostgreSQL data directory.
Step 4: Connect to PostgreSQL Database Without Password
Finally connect to the PostgreSQL database server using any tool such as psql or pgAdmin(In pgAdmin, press ok while it prompts us to enter the password without entering anything in the field):
psql -U postgres
At this stage, we will not be asked for any authentication.
Step 5: Change the PostgreSQL Password
Once connected to the PostgreSQL database, we can set a new password for the postgres user. Use the following SQL command.
ALTER USER postgres WITH PASSWORD 'new_password';
Replace 'new_password' with the new password we wish to set. We should see an output confirming the password update, as shown below:
Step 6: Restore the pg_hba.conf File
Now restart the PostgreSQL database server. At this stage, we can connect to the PostgreSQL database server with the new password. After resetting the PostgreSQL database password, it’s crucial to revert the authentication method back to md5 in the pg_hba.conf file for security purposes. Modify the file to look like this:
# IPv4 local connections:
host all all 127.0.0.1/32 md5# IPv6 local connections:
host all all ::1/128 md5
Then, reload the PostgreSQL configuration to apply the changes:
sudo -u postgres pg_ctl reload
Conclusion
Resetting the PostgreSQL user password is a straightforward process that involves modifying the pg_hba.conf file and temporarily allowing passwordless login. By following these steps, we can regain access to our PostgreSQL database, set a new password for the postgres user, and return our system to a secure state by restoring the original authentication settings. This process ensures that our PostgreSQL password reset is both secure and effective, allowing us to manage our database confidently.
