Manage certificates
Certificates are used when creating secure connections in, for
example, web browser and mail. You can install, view, and
delete certificates.
Certificates are used to authenticate the server or the user.
Do not add new certificates unless you have verified that they
are genuine. Adding arbitrary certificates may decrease the
security of your encrypted connections.
User certificates are typically provided to you by your service
provider or company IT department.
