Hello Susanne,
Unfortunately there currently is no password-reset function on the Farm, nor is there a tutorial on the dashed sentence controller. Feel free to send an email to support@pcibex.net with your Farm username and details (approximate time of registration, list of projects on the account as you remember them) and I’ll reset the password for you. You can look at this documentation to learn more about the options of the DashedSentence controller.
