Authentication Failure

Last updated on Nov 24, 2025

Applies To	Edge Pipelines created with any variant of a database Source.
Error Message Text(s)	- For PostgreSQL and MySQL Sources: `Authentication failed: The specified username or password is incorrect.` - For SQL Server Sources: `Test source connection failed with exception: Invalid username or password. Please check the username and password.` - For Oracle Sources: `The Schema/User does not exist. Please use the correct username and password.`

Potential Causes

The credentials for the database user authorizing the connection are incorrect.
For Oracle Sources, each user account corresponds to a schema. This error occurs when the specified user or its associated schema does not exist in the database.

Verify that the password entered for the authorizing user in the Configure Source page is correct.
Invite another team member with the required privileges to set up the Pipeline. Read Inviting and Moderating Team Members.
For Oracle Sources, verify that the specified user account and its schema exist in the Oracle instance, and ensure that the account is unlocked.

To verify, connect to your Oracle server as a database administrator (DBA) using SQL Developer or any other SQL client tool and, run the following script:
```
-- Verify user exists 
SELECT USERNAME, ACCOUNT_STATUS FROM DBA_USERS WHERE USERNAME =  '<database_user>'; 
-- Check schema existence 
SELECT OWNER, OBJECT_NAME FROM DBA_OBJECTS WHERE OWNER =  '<database_user>';
```
Note: Replace the placeholder values in the commands above with your own. For example, replace <database_user> with hevo_user.
