Second EU Passport is for people who are looking to get just a second Passport from any of the EU member states. With the Second Passport, you will legally use it and travel to Europe as a citizen and this will also come with a Naturalization/Citizenship Certificate which you will have to use to legally apply for other documents such as ID Card and Driver’s license after you have traveled to Europe.
This option is mostly picked by people who have insufficient funds to take the Complete citizenship. So with this, we just have to process your Citizenship and provide just the Passport with Naturalization certificate which you can use the Naturalization certificate to legally apply for other documents from the Country’s authorities. Even after your Passport expires, you have all legal rights to renew.
