This form will search for a farmOS instance based on the email address that was used to registered it. It will then send a one-time login link via email.
This will not work for email addresses that were added to a farmOS after it was registered. It also will not work if you have changed your email address within farmOS after logging in.
If you already know the URL of your farmOS, you can also go there directly to login. If you don't know your password, you can use the "Request new password" link from there.
