Verification is the act of confirming that something is true, accurate, or genuine, such as checking that a document matches known facts. Validation, by contrast, typically checks whether something meets a set of requirements or works as intended, such as testing that a product functions correctly.

Two-factor verification (often called two-factor authentication) is a security process that confirms a person's identity using two separate methods, such as a password and a code sent to their phone, adding an extra layer of confirmation beyond a single check.

Common examples include identity verification when opening a bank account, email verification when signing up for a website, or verifying a fact by checking it against a reliable source.
