Work with Certificates

Use client and Certificate Authority (CA) digital certificates to enable your phone to access VPN or secured Wi-Fi networks, and also to provide authentication to online servers. You can get a certificate from your system administrator or download it from sites that require authentication.


  • Some apps such as your browser or email client let you install certificates directly in the app. See the app’s help for details.
  • You must set a lock screen PIN or password before installing a digital certificate.

  5. If you have more than one certificate in the root folder, select the certificate you want to install.
