Limit devices or seats

An activation limit caps how many devices or seats a single key can be used on. That gently prevents one purchase from serving a whole group, which is exactly the leak you want to close.

Set a realistic number

The limit should reflect how a genuine customer uses your product. Too low and you frustrate honest buyers with legitimate multiple devices; too high and you leave the door open to sharing. The right number fits real use. Related: Protecting Your Product Without Punishing Customers

Allow for real life

Customers replace devices and reinstall. A good activation system lets a genuine user move their license within the limit, so the cap curbs sharing without trapping a paying customer on an old laptop. Related: Validating Keys Without Frustrating Users
