# Providing the REST API Credentials

For security reasons, the Xpress software does not accept the credentials to the Insight Server from the command line or environmental variables. Instead, the Xpress software integrates with the default secure storage mechanism for each supported operating system.

## Windows

When the environment is configured for remote solving, as described in the previous section, Xpress will retrieve the REST API credentials to Insight from the secure storage. The REST API credentials obtained from Insight for your account (see Generating REST API Credentials) need to be entered into the secure storage.

On Windows, Xpress integrates with Credential Manager.

1. To open Credential Manager, type credential manager in the search box on the taskbar and select Credential Manager Control panel.
2. Select Windows Credentials to access the manager.
3. In the Generic Credentials list, click Add a generic credential.
4. Populate the fields as follows:
   - Internet or network address: `ficoxpress:<insight URL>` (for example, e.g. `ficoxpress:http://localhost:8080`)
   - User name: <Client Id value from Insight>
   - Password: <Client secret value from Insight>
5. Click OK, then close the Credential Manager.

## Mac OS

On Mac OS, Xpress integrates with Keychain Access and requires 'application passwords' not 'internet passwords'. Therefore, use of the KeyChain Access UI is not recommended. The command-line security tool should be used which generates 'application passwords'. We also recommend deleting any existing ficoxpress passwords as only the first password will be read by the software.

1. Open a terminal in interactive mode so credential secrets are not stored in your terminal history.
2. In your terminal, first delete old passwords for this URL and then create a new one by typing:
   1. security - i
   2. security> delete-generic-password -s ficoxpress:<url>
   3. security> add-generic-password -s ficoxpress:<url> -a <client-id> -w <secret>
   4. security>
3. Press Ctrl-D to quit the security prompt.

The credentials will now be visible as an "application password" in Keychain.
