02 Authentication Logging in as the first user on a new installation To log in under these circumstances, all you have to do is run nf auth . It will create a key file which the server will automatically accept as there are no configured users. Logging in as a previously created user Simply run nf with whatever parameters you need to achieve your goals. You will be logged in automatically. If you are using a different user name than you were when you set up your account, you can use nf set --user then use nf as normal. Logging in as a new user on an existing system This depends on how your account was set up.
