Up until recently, a passport pretty much covered everything for travel but according to new requirements, that's not going to be enough.

If you're from the United States and intend to travel soon, you may want to look at these regulations coming soon so that you're prepared. Afar is reporting that in 2021, using a passport to get to Europe is not going to be enough.

Starting on January 1, 2021, any citizen from the United States who wishes to travel to the 26 members of Europe's "Schengen Zone" will have to register with European Travel Information and Authorization System (ETIAS) or may be turned away at the border.

The European Union has implemented this to strengthen their borders, but it is not technically a visa. You will need this new registration for: Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, and Switzerland as well as micro-states San Marino, Vatican City, and Monaco.

To get one, you'll have to register online and must have a valid passport, email address, or credit/debit card. Then, once you pass the security and health-related questions, it will be sent via email. It will be valid for three years.
