# Step 1: Change default passwords

For your production server, follow best practices to change the default passwords in the following SQL script files to make the databases more secure.

**Note:** If you are evaluating Pentaho, you might want to skip this step.

1. Browse to the `<*your pentaho directory*>/pentaho-server/data/postgresql` folder.
2. Use any text editor to modify these create scripts as needed according to your existing setup for the user, password, database, and other required information:
   * `create_jcr_postgresql.sql`
   * `create_quartz_postgresql.sql`
   * `create_repository_postgresql.sql`
   * `pentaho_mart_postgresql.sql`
3. Save and close the files.
