OpenSpecimen has a feature that allows only super admins to login to OpenSpecimen.

If a regular user (other than admin) tries to login when this option is enabled, then it shows a warning message on the login screen: “The system is locked down. Please contact the system administrator.”

The standard user can not view/edit this setting. It can be set up only by super admins.

Steps to Enable System Lockdown

Click on Settings → Administrative → System lockdown → Enable/Disable.

By default, the value is set to Disabled.

Open

Click on the ‘Enable’ button and ‘Save’.
