Hi There. I am Bing and I look forward to helping you with your issue today.
Please clarify if the device is Asus Asus X55 series?
Which version of Linux are you using?
What kind of password ***** you referring to? The password ***** log in the Linux OS?
You no need to pay more and I am telling you the answer now.
Follow the steps in below link and reset the password ***** none.
The extra payment is for Premium Service, such as providing remote assistance, which is not suitable in your case. As the steps shown in the above link, you need to physicaly access the target Linux host and reboot for a few times. There is no remote session could help you this way.
Have you already tried the suggestion? Worked? Any issues?
