Append Mode

Applications and devices that don't support the inline Duo Prompt or a secondary passcode field can use append mode. You'll enter both your password and an authentication method into the password field.

How to Use Append Mode

Enter your password and the authentication method you want to use, separated with a comma. It will look something like this:


In place of authentication_method:

Type... To...
password,passcode Log in using a passcode, either generated with Duo Mobile, sent via SMS, generated by your hardware token, or provided by an administrator.
Examples: "mypass123,123456" or "mypass123,1456789"
password,push Push a login request to your phone (if you have Duo Mobile installed and activated on your iOS, Android, or Windows Phone device). Just review the request and tap "Approve" to log in.
password,phone Authenticate via phone callback.
password,sms Get a new batch of SMS passcodes.
Your login attempt will fail — log in again with one of your new passcodes.

You can also add a number to the end of these factor names if you have more than one device registered. For example, push2 will send a login request to your second phone, phone3 will call your third phone, etc.
