What is two-factor authentication and should I use it?
It adds a second check to your login so a stolen password alone is not enough.

Yes, you should turn it on, especially for email, banking and social media.
Types of 2FA
Authenticator apps and physical security keys are stronger than text-message codes. Text codes are still better than nothing.
Set it up
Look for "security" or "login" settings in your account, choose your method and save the backup codes somewhere safe.
Keep access
