What comes first registration or login?

Registration only happens the first time you access the system. It is a way to check your credentials. Every time after your initial registration, you will log on to the system using the username and password you created.

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.

Is login and Registration same?

Registering for something sometimes involves paying money, while signing in or logging in to something usually does not require a payment.

What is registration and login page?

A signup page (also known as a registration page) enables users and organizations to independently register and gain access to your system. It is common to have multiple signup pages depending on the types of people and organizations you want to register.
