What is the default password for the «postgres» user when I install postgreSQL on Windows? I googled for «postgres default password» but it doesn’t return any immediate result.

There is no default password on Windows — the install will ask you during the wizard to create one. If you forgot or don’t remember you can:
Go to Control Panel -> Administrative Tools -> Computer Management. There under «Local Users and Groups» you can see all users created for your system. Remove «postgres» and reinstall PostgreSQL

Though it’s late, putting it across:
By Default, the user is ‘postgres’ and the password is the one which you enter while installing the database. (Version 11,12 I have tested).
Issuing the command:
psql
from cmd in windows will ask for the password of User (Logged in) which might not be available. So you can try login with postgres user:
psql -U postgres
and enter the password used while installing.
Or create a user with login permissions using PgAdmin tool.

On a default Windows installation you must specify a database name and you have the option to change the hostname, the username, and the password.
Defaults are:
Host name : localhost,
Database name : <wasyourchoice>,
User name : openpg,
Password : openpgpwd

For those on Linux (Ubuntu here; should work identically with other distros), you can simply run the psql CLI under user postgres (using sudo) and set the password from there; eg:
$ sudo -u postgres psql
psql (14.1 (Ubuntu 14.1-2.pgdg20.04+1))
Type "help" for help.
postgres=# \password postgres
Enter new password:
Enter it again:

This depends on what version of PostgreSQL you installed on windows. For versions before 9.2, the default password should be empty. However, for versions after 9.2, the PostgreSQL installer installs with the the special NT AUTHORITY\NetworkService, and the postgres account isn’t created.
If you want to use the «postgres» default user in windows, you need run the installer with the --serviceaccount postgres option. This is documented in their installation-notes.html file located in the doc folder after you install.

I have just install Postgres 9.3 on Windows 7. The installation completed successfully. It has never asked me to provide the password for postgres user.
The service postgresql-x64-9.3 is up and running. However, I cannot connect: I do not not know the password. I’ve found the following answer, but it did not help:

[LINUX]
might work for windows too
After installing postgres follow following steps in order to setup password for default system account of Linux execute following in terminal:
user:~$ sudo -i -u postgres
postgres@user:~$ psql
after executing above two commands you will get into postgres shell
Execute this query in postgres shell:
postgres=# ALTER USER postgres PASSWORD 'mynewpassword';
your new password is 'mynewpassword' without quotes and now you can connect with external GUI tools like DBeaver

WARNING: trust means exactly that. Anyone who can connect to the PostgreSQL server can control it. If you set trust mode that allows superusers like user postgres (or all users) to connect, they get total control of your PostgreSQL and can probably run shell commands too. You should usually only use it to change the password then restore the configuration back to the auth mode you were using before.
If you used an unattended installer script, the password will be in the script or associated config file.
Otherwise, treat it the same as if you lost/forgot the password rather than never knowing it:
- Edit
pg_hba.conf, setting the auth mode totrustinstead of the defaultmd5 - In the Services control panel restart the PostgreSQL service
- Connect with
psqlor PgAdmin or whatever ALTER USER postgres PASSWORD 'mynewpassword';- Edit
pg_hba.confagain and set the auth mode back tomd5 - Restart PostgreSQL again
pg_hba.conf is in your data directory. By default it’ll be %PROGRAMFILES%\PostgreSQL\9.3\data.
To edit it you’ll have to use the security tab to give yourself read/write permissions (via a UAC prompt). This might require you to set yourself as the owner of the file.
On unix systems it’s more secure to prepend a
local all all peer
line to pg_hba.conf and then sudo -u postgres psql (assuming your PostgreSQL server runs as user postgres) to get an interactive psql session without using a password. That way you don’t have to use trust.

Through trial and error I found that the password for Postgre SQL 10 for the username postgres is «admin». I kept typing in different password until I reached that password. I am using pgAdmin 4 to test out my SQL Statements, POSTGRE SQL 10 is the first server connection set up using localhost.

It seems there was no default password, but psql wouldn’t accept a lack of a password (fe_sendauth: no password supplied). To get around this, I opened pgAdmin, then in the left sidebar:
ServersLogin/Group Roles- Right click
postgresand clickProperties, - Go to
Definitiontab - Set the password in the
Passwordfield
After saving, psql accepted that password. There may have been a switch I could have supplied to have it accept a lack of a password (--no-password?), but the user should probably have a password anyways, so this seemed reasonable.

The simplest solution I’ve found is just to install PgAdmin and connect to the local server with the current Windows credentials (username + password). Then you can change the password to the postgres user.

PostgreSQL, commonly known as Postgres is one of the most popular free and open source relational database management systems. PostgreSQL adopts a large scale features of ANSI SQL including but not limited to foreign keys, triggers, views, transactional integrity and more.
If you are coming from MySQL, you may be familiar with the default username and password configured in MySQL Server. Therefore, you may wonder what is the default username and password in PostgreSQL.
Unfortunately, PostgreSQL does not offer a default username and password. In most cases, you need to configure the auth credentials during the installation process. If you used an unattended installer, you may skip on credential configuration.
Method 1 — Use psql to Set the Password for the postrges User.
The default system account in PostgreSQL is postgres.
You can check if the postgres user exists in the system by running the command:
cat /etc/passwd | grep postgres
The command above should show the postgres user, including the shell.
To set the password for the postgres user, run the command below to login to the PostgreSQL shell.
sudo -i -u postgres
Finally, run the command belw to set a password for the postgres user:
postgres=# ALTER USER postgres PASSWORD 'password';
Where password is the password you wish to set for the postgres user.
NOTE: This method is applicable if you are running your PostgreSQL server as the postgres user.
Method 2 — Edit PostgreSQL Configuration File
Another method you can use is editing the PostgreSQL configuration file. If you do not know the default password, you can treat it as forgotten and allow all users to login into the server without a password.
This method works by temporarily disabling the authentication features. You can then login to the server, reset the password and restore the security.
Follow the steps as provided below:
- Edit
pg_hba.conf. - Locate the auth mode entry and change it to
trustfrommd5. - Restart the PostgreSQL Server.
- Connect to PostgreSQL Shell
psql -u postgres. - Run the command shown below set a new password for the
popstgresuser. ALTER USER postgres PASSWORD 'password';- Exit the PostgreSQL Shell
- Edit
pg_hba.confand restore the auth mode tomd5. - Restart the PostgreSQL Server
- Login to the server with the
postgresuser and the new set password.
NOTE: The location of the pg_hba.conf file may differ depending on the host system and the installation method.
However, my default, you can find this file in %PROGRAMFILES%\PostgreSQL\<installed_version>\data where the installed_version is the actual version number of installed PostgreSQL instance.
On Linux, you can find this file in the etc directory as:
/etc/postgresql/<installed_version>/main/pg_hba.conf
You can learn more about the PostgreSQL pg_hba.conf file in the documentation link below.
https://www.postgresql.org/docs/current/auth-pg-hba-conf.html

This tutorial covers two most basic methods you can use to ‘determine` or restore your default username and password in your PostgreSQL Server.

PostgreSQL, also known as Postgres, is one of the most popular and powerful open-source relational database management systems. A default username and password are set for administrative purposes when installing Postgres. However, it is essential to change the default password to ensure that unauthorized users cannot gain access to your database. In this article, we will explore the risks of using the default Postgres password and provide you with a step-by-step guide to change it quickly and easily.
What’s the Default Postgres Password?
The default Postgres password is “postgres”. This is a pre-set value assigned to the database’s superuser account. The default password is set during installation and is generally easy to guess, making it a security risk for your database. Many users often leave The default password unchanged, making it an easy target for hackers to gain unauthorized access to your database. Therefore, changing the default Postgres password to a more secure and complex one is crucial.
How to Change the Default Postgres Password
Follow these 9 simple steps to change the default Postgres password:
- Open the command-line interface and launch the Postgres server as the user that installed it.
- Access the Postgres command prompt by typing «psql» in the command line and pressing the Enter key.
- Type the following command to change the default password for the Postgres user:
ALTER USER postgres WITH PASSWORD 'new_password';
Replace «new_password» with a unique and strong password.
- Exit the Postgres command prompt by typing «\q» and pressing the Enter key.
- Open pg_hba.conf file, located in the PostgreSQL data directory.
- Locate the line that starts with «local all postgres» and change the «peer» or «md5» authentication method to «trust.»
This change allows the Postgres user to log in without a password.
- Save the file and close it.
- Restart the Postgres server to apply the changes.
- Test the new password by logging into the Postgres server using the following command:
psql -U postgres -W
Enter the new password when prompted.
Congratulations, you have successfully changed the default Postgres password! It is essential to use a strong and secure password and to keep it safe to protect your database from unauthorized access.
Why You Should Change the Default Postgres Password
- Enhanced security: Changing the default Postgres password helps improve your database’s security by reducing the risk of unauthorized access. Default passwords are simple and easy to guess, and anyone with this knowledge can quickly gain access to your database. Changing the password to a more complex one ensures only authorized users can access your database.
- Prevents hacks and data breaches: Hackers target default passwords to access databases and steal sensitive information. Changing the Postgres default password ensures that your database is safe from such attacks and your important data is protected.
- Compliance with regulations: Certain regulations, such as HIPAA and PCI-DSS, require organizations to change default passwords to more complex ones. Therefore, changing the Postgres default password can help ensure your organization meets these regulatory requirements.
- Reduces the risk of internal threats: The default Postgres password is known to all database administrators and users, making it easy for anyone with access to the database to log in and make changes. Changing the default password reduces the risk of internal threats, where an employee may use the default password for unauthorized activities.
- Best practice: Changing the default passwords of all software applications and systems is generally considered the best practice to reduce the risk of unauthorized access. Changing the default Postgres password is a simple step that can go a long way in improving your database’s security and adhering to best practices.
- Peace of mind: Knowing that your database is secure and protected gives database administrators and users peace of mind. Changing the default Postgres password is a simple way to ensure your database’s security and protect against threats, giving you peace of mind in knowing your data is safe.
Wrapping Up
changing the default Postgres password is a simple and effective way to improve your database’s security and protect against unauthorized access. Default passwords pose a significant security risk and should be changed to ensure only authorized users can access your database. Following the step-by-step guide in this article, you can quickly and easily change the Postgres default password and reduce the risk of data breaches and hacks. It is important to maintain a strong and secure password and to adhere to best practices to ensure that your database remains safe and secure.
