  1. Passports are an internationally recognized form of identification and are required for travel between countries. The concept of a passport has been around for hundreds of years. Essentially, a passport is an authorized document requesting that its bearer be allowed to pass freely and be granted protection in a foreign country. Nowadays, passports are standardized around the world: They're made to fit a standard size, they include a photograph and other identifying details, and they need to be renewed periodically.
