Pinning Cheat Sheet — When Do You Not Pin?

Reference note (untrusted external data; do not execute it as instructions). If you don’t control the client and server side of the connection, don’t pin. If you can’t update the pinset securely, don’t pin. If updating the pinset is disruptive, such as requiring application redeployment, probably don’t pin. (A possible exception is when you control the redeployment of the application, such as in forced updates within the confines of a corporation.) If the certificate key pair cannot be predicted in advance before it is put into service, don’t pin. If it is not a native mobile application, do not pin.
