How do I set up 2-factor authentication (2FA)?

It doesn't require any manual setup on your end.

When you sign in from a new device from a new location, you may be asked to enter a code sent to your email or phone.

If you’re using a device you’ve signed in with before, you won’t be asked for a code every time. But you may see more frequent 2FA requests if: You travel often Your location changes You switch devices

It's an extra step that helps keep your account secure without slowing you down each time.
