# Licenses > Issue\, binding\, limits\, rotation and suspension\. *Billing \& payments → Account \& licenses* A License is the authorisation object that lets the Expert run\. It is issued per entitlement and is never transferable\. | Property | Behaviour | | --- | --- | | Scope | One entitlement\, one active MT5 account | | Binding | Broker\, server\, account\, device and IP | | Visibility | Masked in the workspace\; only you and an authorised operator can reveal it | | Rotation | Operator\-reviewed\, audit logged\, previous binding invalidated | | Suspension | Immediate\; the Expert stops authorising | > **TREAT A LICENSE LIKE A PASSWORD** — Do not paste it into a ticket\, a screenshot\, a forum\, or any chat\. Support never needs the full value\. ## When to request rotation - You changed broker or the server name changed\. - You replaced the machine that runs the terminal\. - You believe the value was exposed\.
