How do I register an account without remembering passwords?

I found a laptop on http://www.renewone.de. But no account registration is needed. Does anyone have experience with online shopping without logging in to their account. Does it work with shipping and tracking, etc?

You have to be a little more specific with your "… No account registration…"!

Which account are you talking about? If you mean an online account - i.e. Microsoft, Google, Samsung, Lenovo, Facebook, Twitter etc. - such an account is not absolutely necessary.

On the other hand, you have to be able to specify an email account if you want to shop online. The seller needs a way to communicate with you. He informs you about the current status of your order and sends you, among other things. The request for payment, the invoice and / or other documents. In addition, he gives the transport data to his parcel delivery company so that he can provide you with the tracking data (shipment tracking).
