Yes. However, we strongly advise you make serious background research. Not all online service providers are genuine, and if you fall in such hands, you will not like the experience. Genuine providers are cautious about their clients’ data and work to ensure it is not susceptible to online theft.
You will never hear such providers asking you for sensitive information like passwords. If anyone asks you for such things, you are dealing with a scammer, and you should stop negotiating with them.
