# Import PFX Certificate

The **Import PFX Certificate** option allows you to import a code signing certificate using a PFX file that includes the certificate private key. This certificate is used to sign content published by the Publisher.

When importing a new certificate, the Publisher checks whether an existing certificate is already configured. If the current certificate is still valid, you are prompted to confirm before it is replaced. This helps prevent accidental replacement of an active and trusted signing certificate.
