An "Age Gate" is a digital tool used on websites and applications to restrict access based on a user's age. It typically requires users to enter their birthdate or confirm that they are above a certain age, ensuring compliance with legal regulations regarding age-restricted content, such as alcohol, tobacco, or adult entertainment. Age gates help protect minors from accessing inappropriate material and assist businesses in adhering to laws like the Children's Online Privacy Protection Act (COPPA). By implementing age verification, companies can create a safer online environment while also minimizing legal risks associated with underage access.
