ORA-01017 Error in Oracle Developer Tools for VS Code

I am unable to connect to the database due to an ORA-01017 error. I have two types of accounts: a personal account and a team account, which are formatted as follows:

• Personal account = user_name
• Team account = user_name[team_name]

I can easily connect using my personal account, but I can't seem to connect with the team account.

Full error message:

ORA-01017: invalid username/password; logon denied https://docs.oracle.com/error-help/db/ora-01017/. Network config file location: /Users/.../Oracle/network/admin

What's puzzling is that I can connect using user_name[team_name] in other tools like DBeaver and PL/SQL Developer without any issues.

Using "user_name[team_name]", 'user_name[team_name]', and user_name\[team_name\] hasn't resolved the issue.

Version: Oracle Developer Tools for VS Code (SQL and PLSQL) = v23.4.1

The square brackets indicate that you're trying to connect as a proxy user.

The Oracle Developer Tools for VSCode have some extra steps you need to take for this type of authentication:

check the Show more options checkbox and provide the proxy username and password

In your example, the "proxy username" is user_name; the password is that user's password.

For the "username", you'll enter team_name; the password for that should be blank.
