Customer Profile Registration and Commercial Registration Certificate Issuance. All customers that have created online account need to provide customer registration information, which is used to capture customer profile as well as generate and issue commercial registration certificate.

Should I login after registration?

It can be safe to auto login if the user already has an active session as the correct user during the confirmation step. If you think about it, it's not actually "automatically logging them in" but simply keeping them logged in as they was before. During all that time, there was no reason to end the session.
