If you are not able to get into your Egnyte account, you can reset your password by using the "Forgot password" option on the login page.
Note that this option is only shown on the second step of the login flow. You will need to provide a valid username or email before you can reset your password.
You will see a screen like this once you click the "Forgot password?" link. Click "Continue" to proceed.
You will receive an email containing a button that will take you to a page where you can reset your password. This button can only be pressed once, and will only be active for two hours.
