I forgot my HTC Account password. Can I reset it?
Check your email for further instructions. On the email, click the Reset your HTC Account password link to confirm your request. The link will expire within an hour if not used.
If you didn't receive the reset password email, check your spam mail or resend another email by clicking Forgot your password? again.
If you used a social network account when you registered for an HTC Account, you would need to reset your password from your social network account.
