Workspaces are provisioned by K1.

There is no self-serve sign-up. K1 sets up your organization and issues its founding Project Manager credential as a single-use invite link; the Project Manager then invites the rest of the team from Settings. Every password is set by its owner — K1 never holds one.

Have an invite link? Open it — it signs you in. Expecting one that never arrived? Ask your project manager, or your K1 contact.
