In a text message, the passcodes come in a list of 10. This option is useful if the you are an area with limited mobile service. IdentityNow provides a hint in the strong authentication prompt by indicating the starting number of the passcode in the list that is needed to authenticate.
NOTE: When you are prompted for strong authentication, you might have the opportunity to request additional passcodes.
You might receive a passcode from your Duo mobile app.
You might contact an administrator to request a passcode, also known as a bypass code, that the administrator can generate and provide to the user.
