I created a database using the GUI of pgadmin and it works well. I can connect to the server with my password. But when I want to connect to the database using psql in terminal, after I enter the password, it says
psql: FATAL: password authentication failed for user "{username}"
I tried every possible password, but it's still not working.
Has anyone meet this issue before?

I can't connect on postgresql.
when i go on pgadmin>server>postgresql, it asked me "please enter the password for the user 'postgres' to connect the server?
I have windows 10 and postgresql 14.
But I don't have this password.
What can I do?
The following worked for me.
Change METHOD of all rows in your pg_hba.conf file from scram-sha-256 to trust (C:\Program Files\PostgreSQL\14\data\pg_hba.conf). This will disable password for your DB.
Click on any database in postgresql to use Query Tool.
In Query Tool type ALTER USER postgres WITH PASSWORD 'User_password';
postgres is default username, execute it.
This way you can set up a password for your DB, after that go back to the first step and change it back from trust to scram-sha-256.
I am following a tutorial on how to create a to do app with PERN stack.
(working on ubuntu 18.4, postgres version 12.3)
I did install the PostrgreSQL, server is running on 5000 and I am able to enter to the database from the command line with "psql -U postgres" but when I try to connect database with the server I am getting this error: password authentication failed for user "postgres".
I was not asked to give any password to the user "postgres" while instalation so I left the password in the db file empty.
My db file looks like this:
const Pool = require("pg").Pool;
const pool = new Pool({
user: "postgres",
password: "",
host: "localhost",
port: 5432,
database: "perntodo",
});
module.exports = pool;
what can I co?
I did set the postrgres authentication in pg_hba.conf file from peer to trust as I found in another issue on stockoverflow, but the error keeps appearing.
The immediate fix would be to eliminate:
host: "localhost"
from your connection settings. This would force the connection to be made on local which would be equivalent to what you are doing with psql -U postgres.
The longer term fix would be to use psql -U postgres to connect and then ALTER ROLE postgres WITH PASSWORD '<some_pwd>'. This would give this ROLE a password. You can do this with other roles that already exist by using ALTER or when you CREATE a new role in the create statement.
The connection authentication methods are controlled by the pg_hba.conf file. A full explanation of what it does is available here:
https://www.postgresql.org/docs/current/auth-pg-hba-conf.html
If the above does not answer all your questions then come back with specific concerns.
Don't use user postgres to connect your application to PostgreSQL.
Create separate user for application.
Grant to application user strict permissions only for schemes and tables what it need access.
Add pg_hba.conf record for application user
Enjoy
If I go as per your error message, then you need to reset postgres password. And I believe the default isnt working or you might have forgotten after resetting it.
Please follow below tutorial for resetting password:-
https://docs.bitnami.com/aws/infrastructure/postgresql/administration/change-reset-password/
or refer the answer for below:-
What is the default password for Postgres
I'm using PostgreSQL for the first time and I am not familiar with it. When I start pgadmin and enter master password and when I want to connect to postresql and again enter same password following error pops up:
could not connect to server: could not initiate GSSAPI security context: The operation or option is not available
could not initiate GSSAPI security context: Credential for asked mech-type mech not found in the credential handle
FATAL: password authentication failed for user "postgres"
Whats the problem here?
I just had the same issue and below is how I solved it. Because you don't have a default password for the user 'postgres', you will need to set one first, like this :
Connect to the terminal as the user 'postgres' with the current admin credential (thanks sudo)
sudo -u postgres -i
Connect to the database 'postgres'
psql postgres
(optional) If the psql command is not found, you can the PostgreSQL bin path to your $PATH like this :
export PATH=$PATH:THE_PATH_TO_POSTGRESQL_BIN_FOLDER
# Example : export PATH=$PATH:/Library/PostgreSQL/12/bin
Change the password of the user 'postgres'
--- Do not forget to my_password with the desired password
ALTER USER postgres PASSWORD 'my_password';
In the pgAdmin windows, try to connect with this new password, it should work.
It is ridiculous but my solution after many trial was very very simple.
Problem seems that password is not match or connection problem. So, first make sure your password is definitely correct. You might think you enter exact same but it might be not. I tried to wrote a password to somewhere else that i can see it is correct.Then, i copied that and paste it to setup where you put your new password. Ofcourse you have to remove postgre completely for this to try.
When setup is completed, if you tried and didn't work again, then delete Postgre server and create new one. Just enter server name, connection address and password and save. if this one also not work successfully,maybe you should check if the chosen port number is alive or not for postgre server.
Sorry for that answer is not visual and some english mistakes. I just wanted to wrote really fast. Good luck :)
I tried to create server it it says:
Unable to connect to server:
FATAL: password authentication failed for user "postgres"

What operating system are you using? maybe you need to change the password of the postgres user. In my case I use Debian GNU Linux, to change the password of the postgres user, I do it in the following way:
root#alpha:~$ passwd postgres
and then I enter a new password for the user.
Could you also verify that the postgres user has permission to connect to the server? To do this, you can check the pg_hba.config file in the PostgreSQL. installation directory.
root#alpha:~$ nano /etc/postgresql/11/main/pg_hba.conf
By default PostgreSQL, only allows connections from local addresses (localhost)
Make sure to have your local postgres server running
Hit pgadmin tool connect to server and to create database
Right-click on the server button to your left, select create then server, insert name of the server, make sure it is as descriptive as possible, that way you can find your way back to if you remember
Move to connection tab; host name is the server where the SQL database is running, most likely you will be starting with your machine as database(db), insert localhost or 127.0.0.1.
leave default port as it is '5432'
maintenance db leave as 'postgres'
username leave as default 'postgres'
password : same as you registered with during installation
To your left, you should see the database under 'server', you should see the postgres default created underlink databases.
Right click on the databases button and select create, then database, insert your descriptive database name, click save.
Click on your new database, roll down, highlight Schema, go to Tools, select Query Tool...
You can go ahead to create or import tables as you deem fit.
EMPHASIS SHOULD BE ON THE PASSWORD, IT MUST BE SAME AS USED DURING INSTALLATION
I am connecting postgres database with wrong password and connection string and user role is correct and still i am able to connect the database?
How its possible?
when you are connecting with database there is a situation when postgres does not ask for password
1. when you are installing the postgres and creating localhost server first time and making connection without password than it needs only the correct following :-
1. username or userrole
2. correct connection string
