Several workspaces, one login
Run a side project or a second business from the same email, with no extra account.
Use one email for everything. Create another workspace for a side project, a client or a second business and switch between them from the workspace menu. Each workspace keeps its own files, branding, domain and team.
You can own up to 10 workspaces, plus one more for every paid workspace you own.
Up to 2 of them can be on the Free plan.
You can also link a workspace owned by another account to use it from yours.
