OpenCredentials is a sandbox setting in Sandboxie Ini. It is typically specified as OpenCredentials=y (see Yes Or No Settings), and indicates that Sandboxie should not isolate Windows credentials in the sandbox. For example:
Indicates that programs running in the DefaultBox sandbox will update the real credential store, rather than a sandboxed instance of it.
Windows credentials are used primarily by Windows and Microsoft applications to store user name and password information for:
- Network shares
- Microsoft accounts
To manage Windows credentials, start Control Panel > User Accounts, select an account, and the click on the Related Task labeled Manage my network passwords.
Note: Sandboxie stores credentials in the sandboxed protected storage. Thus, if the setting Save outside sandbox: History of search strings and invoked commands in Sandbox Settings > Applications > Web Browser is enabled, credentials will not be stored in the sandbox, regardless of the OpenCredentials setting.
