Working with secure certificates
If your organization’s VPN or Wi-Fi Network relies on secure certificates, you must obtain the
certificates and store them in your phone’s secure credential storage, before you can configure
access to those VPN or Wi-Fi networks on your phone.
If your network administrate instructs you to download the certificates from a website, you are
prompted to set a password for the credential storage when you download the certificates.
