# Step Two: Create the Encrypted Password

Create the encrypted password using the key file that you generated in the previous step. Skip this step if you're using OAuth for login authentication.

:::note
The Data Loader command-line interface is supported for Windows only.
:::

1. In the same command prompt window, enter the following command.

   `encrypt.bat -e <password><Salesforce_Security_Token> <key path>`

   Replace `<password>` with the password that you use to log in to Salesforce in Data Loader combined with your org's [security token](https://help.salesforce.com/s/articleView?id=xcloud.user_security_token.htm\&type=5) (no space in between). Replace `<key file path>` with the file path you created in the previous step.

   For example, if your Data Loader password is `myP4sswordsRock` and your org's security token is `00DE0X0A0M0PeLE!AQcAQH0dMHEXAM`, then the command is:

   ```nolang
   encrypt.bat -e myP4sswordsRock00DE0X0A0M0PeLE!AQcAQH0dMHEXAM C:\Users\jjang\.dataloader\dataLoader.key
   ```

2. Copy the generated encrypted password string. You use this value in a later step.
