This page shows examples of the messages Cmd may display in your terminal sessions on Cmd-enabled servers, along with what they mean, and (if applicable) how you should respond.
Note: Many of these messages can be customized.

Custom terminal message

A Cmd trigger has fired due to an action you undertook, and is displaying a custom message.
Note: In the above example, the command has also been blocked (by the 'Block command' action). While the 'Display custom message' action is often useful alongside the 'Block command' action, displaying a custom message does not require interfering with server operation.


Enter your email for authentication

A trigger has fired due to an action you attempted, and you must provide authentication to complete the action (i.e. to connect to a server, execute a command, or change a file).

Enter the email address associated with your Cmd account, then select one of the 2-factor authentication methods that you have configured:

Provide the corresponding password or code:

If you choose to authenticate via webauth, the system will provide you with a URL to visit, where you'll type in your Cmd password.

If you choose another method, enter the relevant code instead.

Please wait while someone is approving your request.

A trigger has fired due to an action you attempted, and an authorized Duo Security user must approve or reject it.

If approved, you will see the terminal prompt return, and can continue as normal:

If rejected, you will see this screen instead and should contact your system administrator before trying again:
