Two-Factor Authentication

Two-factor authentication adds a second check — such as a code or app confirmation — on top of a password, making a child's accounts much harder to hijack. Helping children turn it on for their key accounts is one of the simplest protective habits; the official guide is linked below.

The second factor matters because it changes what a stolen password is worth: the credential alone stops being sufficient, which is a different kind of protection from making the password harder to guess.

The factors are not equivalent to one another — a code sent by message, a code generated by an application, and a hardware key do not resist the same things — and it is the resource cited here, rather than this page, that sets out those differences.
