WhatsApp update rolls out two-factor authentication for all users, helping keep messages safe

WhatsApp has finally added two-factor authentication to its app, letting people make sure their messages are kept safe. The change helps keep people from breaking into your WhatsApp account and reading your messages, even if they have a password. But it must be turned on manually and requires the latest version of the app. Two-factor authentication, often shortened to 2FA, allows people to keep their accounts more secure than just with a password. It also ties that same account to something else – like an email address or phone number – that anyone looking to get into the account needs to have access to as well.
