# Enter credentials and test the connection

6 min

An app needs credentials for the connected system. This lesson shows where the values are entered, why they are maintained per environment and how the connection test shows whether they are correct. Error messages point to the cause. The values come from the connected system.

## Key takeaways

- Credentials are maintained per environment.
- The connection test checks the values right away.
- Error messages name the likely cause.
