Accounts
There is nothing to log in to yet, and that is on purpose.
You do not need one
Floza runs entirely on your own machine. Your courses are saved on it, not on a server somewhere, so there is no account to make and nothing of yours is held anywhere else.
Accounts will arrive when there is something they are actually for: syncing work between your laptop and your desktop, sharing a course with a colleague, or paying for a plan. Making you sign up before any of that exists would be asking for your details in exchange for nothing.
When accounts arrive
What they will be for
Your work on more than one machine, sharing a course, and paying for a plan.
What they will not be for
Reaching your courses. Anything you build now keeps working without an account, and published files never check in with anybody.
Will I have to make one?
Only for the parts that need one. Building and publishing will not.
