ORA-01017 invalid username/password as default role oracle developer

Question

So, I am trying to make a connection to an oracle database through oracle developer but I am constantly getting invalid username/password. I was given a tnsnames.ora file to connect with. I tried using a basic connection with information I physically read from that tnsname file and I tried connecting with the TNS connection. With both I used the default role since the sysdba gave me the .ora file. With the tns connection, the network alias shows up. I think the connection is made and it has to due to with username/password. I am wondering if there can be issues with ORA-01017 that are in no relation to the username/password that I can troubleshoot before asking again if the username/password given to me was incorrect.

Answer 1

No. An ORA-01017 always indicates an invalid username & password, just as the error message indicates.

Now, of course, it is possible that you've been given the connection information for the wrong database such that the username & password are correct, just for a different database. But as far as the database you're connecting to is concerned, you'd still have an invalid username or password.
