A sub-user is an additional account created under a main proxy subscription, allowing separate access with its own settings and usage limits. It lets a business share one overall plan across multiple team members or projects.
The account owner creates sub-user profiles from the main dashboard, each with its own login credentials or API key. The owner can assign specific bandwidth limits, thread limits, or IP location access to each sub-user, controlling exactly how much of the main plan each one can use. Usage from each sub-user is typically tracked separately in reporting, making it easy to see which team or project is consuming resources. This setup avoids the need to buy and manage completely separate subscriptions for each team member.
This is largely a plan and configuration choice, not a technical limitation.
USER-sub-user-session-task01Everything lives in the username -- add "sub-user" to any proxy credential to apply sub-user to a single task. Swap "task01" for a new label to spin up an independent, isolated identity.
KnoxProxy sticky sessions persist up to 30 minutes on residential (60 on mobile), and the window refreshes with activity.
Each session or connection label gets its own exit, so parallel identities never collide.
This costs nothing beyond bandwidth -- successful responses are billed, not the session or connection itself.
Run as many parallel sessions or connections as the job needs -- concurrency is not capped on any plan.
An agency running proxy access for five different client projects creates five sub-users, each with its own bandwidth cap, under one main account.
Sub-user accounts make it easier for teams and agencies to manage shared proxy resources without losing visibility into individual usage. This feature is especially useful for businesses billing clients separately for proxy-related work.
Many providers let the account owner set specific limits and access rules per sub-user. The exact controls available depend on the platform.
This depends on the plan tier. Higher-tier or business plans generally allow more sub-user accounts than entry-level plans.
