Add and remove certificates

If an app or network that you want to use needs a certificate that you don't have, you can install that certificate manually.

Digital certificates identify computers, phones, apps and other devices for security. Just like you'd use your driver’s licence to show that you can legally drive, a digital certificate identifies your device and confirms that it should be able to access something.
