When you create your first data campaign, LeadPost automatically creates an FTP site to automatically feed matched data to, as well as to receive suppression data from, if applicable. If you need to access your FTP credentials or reset the FTP password, you can click on Account >> Credentials.
If you'd like to reset your FTP password, you can click the 
button, which will generate a new password. However, please note that the prior password will no longer function once this reset is done.
