I'm new and just started Oracle. I installed Oracle SQL Developer[Version: 19.2.1.247] and now I want create new connection but I'm not able to create and found an error like :
Status : Failure -Test failed: ORA-01017: invalid username/password; logon denied.
I am sure about I didn't made a mistake into entered wrong or incorrect credential. if I am so please tell me about that and also tell me the solution to solve this error.
check attachment below.
Well your error message is straight forward. The connection details (username & password) are incorrect. The solution for this error is simple --> enter the correct credentials.
Now, you said that you have installed SQL-Developer. SQL-Developer is just a tool (program/software) used for accessing a Database. In this case, my question would be: do you have a database to which you want to connect to? Based on your screenshot, I see that you are using the default HOSTNAME/SID/PORT, meaning that you either forgot to enter your Database details or you created a username on your local Database (created when you have installed ORACLE Client and followed all those instructions).
If you are trying to connect to an already created Database, make sure that the HOSTNAME/PORT/SID are the ones belonging to the Database and not the standard one.
If you created a username on your local database, then you either forgot your password or you used some invalid characters which can no longer be used right now. Try resetting the password of that user, using another user (via ALTER USER) or using the SQL Developer (right click - Reset Password) with your old password.

I'm trying to connect with a new user that I recently made but when I try to making a new connection this error appears
I acces to the database , scroll down to Other users , right click and click on Create user.
And I'm sure of that user exist and I'm writing the username and the password correctly.
Thank you all ! I found the mistake.
I was connecting to the Database by this way :
And when I was in that session making the New User, the user was not being created because I was doing it without SYSDBA Role. After, I was trying to login with the user I was just "created", but since I had not created it with SYSDBA Role, the system threw me the error ORA-01017.
When I realized that , I right clicked the DataBase and I checked the Properties.
And effectively I was login in without the SYSDBA Role , so I fix that , I enter the username , password and the SYSDBA Role.
After that , I connected to the Database with the Role SYSDBA user. I created the New User I was trying to making and finally it worked when I log in with it !!!
You did not provide enough info, but one of the many possibilities is that your PATH variable is broken. Or you have old connection files that even with the right user/pass they point to the wrong server,service,name. Try to download new instant clients. I will give you some examples:
instant client basic lite win64 12.1.0.2.0
instant client sqlplus win64 12.1.0.2.0
A fact about the Sql developer OS authentication is that Sql developer always tries to authorize by substituting to the user name \ without domain name.
I'm trying to create a new database after installing Oracle Database 18c.
when I get to the second page, I always get an error of [DB T-10304] Oracle home user password is not correct.
I get this no matter what I put in there.
Any suggestions? thanks

I ran into similar issue with 12c on Windows Server 2016. Because the Oracle Home user is a local account, review the local security policy and verify that it is not blocking "Local account" from accessing the computer over the network.
good morning I am writing because I am trying to connect to an oracle 12c database that is in an oracle container, the question is what I am doing with a user that created but I get the error ORA-01017:
On the other hand, if I try the system user with his password that can be obtained at the following link: https://hub.docker.com/_/oracle-database-enterprise-edition?tab=reviews, everything works fine and the connection it's correct:
As you can see below the user is already created and I can even connect from the server to the database:
Try applying what you say in this question: ORA-01017 Invalid Username/Password when connecting to 11g database from 9i client but no change my problem
Update: for some reason the changes I am making through the console I am not seeing with the SQL Developer client, I do not understand why this happens, attached evidence, where you can see that the user cesar created through the console is not visible on the server
I have already installed sqldeveloper and i can launch SQLdeveloper client on my Linux Ubuntu 16.04 system.
The problem occurs during the first attempt of the new oracle connection from the client.
Error returned:
"I/O: The Network Adapter could not establish the connection"
I have already tryed several times to connect at the database but i still missing the username and password.
Is it possible to configure username and password for SYS/SYSTEM(or who else) user after installation?
Full stop.
You don't have a database.
Installing SQL Developer is just giving you a client you can use to work with an existing Oracle Database, which we often refer to as the 'server.'
SQL Developer is not a database.
So you need to get one.
Then you can use SQL Developer.
You have a few options. I talk about them in detail here.
SQL developer is just like the Key for Safe lock. And Database is the Safe.
So right now you have the key for Safe but doesn't have Safe.
Please get the safe first.
SQL Developer is not the Database. So Installing SQL developer will not give access to DB
Instead SQL Developer is the client side tool to retrieve the data or to do the modification on Database.
To get the database you need to download oracle DB from below link

recently I had to change my computer name and now I am getting this error whenever I try to connect to my local oracle 11g express edition database via OracelSQL Developer.
I have already changed my listener and
tnsnames(D:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN) to reflect the my
computer's new name but I am still getting this error.
Any help would be appreciated.
Thank you
You must be using operating system authentication OPS$ prefixed username. Connect with sys or system and fix your DB user account. Search for OPS$ user in Oracle documentation for more details.
