I wish to higher the security level of my account. How do I activate/deactivate 2-step verification?

If you use direct HTC account log in, you can enable 2-step verification by visiting Login & Security tab on HTC account website (account.htcvive.com). Go to Recovery Method & 2-step Verification, click on Activate next to 2-step verification. Follow the instruction to complete the process. After activation, you will need to provide both your log in credential AND a set of verification code sent to you each time you login.

Please note login via social media cannot use the 2-step verification log-in service.
