Add & 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, and apps for security. Just like you'd use your driver’s license to show that you can legally drive, a digital certificate identifies your phone and confirms that it should be able to access something.

Important: Some of these steps work only on Android 9 and up. Learn how to check your Android version.

Install a certificate

  1. Open your phone's Settings app.
  2. Tap Security & location And then Advanced And then Encryption & credentials.
  3. Under "Credential storage," tap Install from storage.
  4. In the top left, tap Menu Menu.
  5. Under "Open from," tap where you saved the certificate.
  6. Tap the file. (If needed, enter the key store password. Tap OK.)
  7. Type a name for the certificate.
  8. Pick VPN and apps or Wi-Fi.
  9. Tap OK.

If you haven't already set a PIN, pattern, or password for your phone, you’ll be asked to set one up.

Remove custom certificates

Important: Removing certificates you've installed doesn't remove the permanent system certificates that your phone needs to work.

  1. Open your phone's Settings app.
  2. Tap Security & location And then Advanced And then Encryption & credentials.
  3. Under "Credential storage," tap Clear credentials And then OK.
