i cant login how do i restart freedombox to make a new username and start from scratch again?

i am only getting the option to log in and not to sign up.

how do you delete all files so freedombox makes you register a new account

i forgot the password for my account

If you just installed FreedomBox, the easiest thing might be to re-flash your SDcard and start from scratch.
As far as I know the first user (the admin) is required for creating any new users – if you lost access to that I don’t think it is trivial to fix that.

If you can, just re-download and re-flash your SDcard and create a new admin user that way.
