Can I use the same key on multiple Cursor installs that I personally control?

Technically a single key can be configured in multiple trusted environments, but you should still manage access carefully. If you want cleaner isolation between work, personal, or team use, separate orders or separate keys are easier to reason about.

• Use the matching reference page Open the linked docs or trust page below instead of guessing the next step from memory.
• Keep the order number if payment or delivery is involved That is the fastest way for support to trace what happened without asking you to repeat the whole story.
• Escalate early if the answer does not match your live case If your real order, setup, or delivery state looks different, switch to support quickly instead of waiting for the issue to compound.
