MFA adds a second verification step, so even if a password is compromised, attackers can&#8217;t sign in without the second factor.<\/p>\n  <p>For more insights, see <a href='https:\/\/security.google.com\/' target='_blank' rel=\"nofollow noopener\">Google Security<\/a> and the overview at <a href='https:\/\/en.wikipedia.org\/wiki\/Password' target='_blank' rel=\"nofollow noopener\">Wikipedia: Password<\/a>.<\/p>\n  <p>External resources like <a href='https:\/\/www.whatsapp.com\/' target='_blank' rel=\"nofollow noopener\">WhatsApp<\/a> often rely on strong authentication to protect user accounts, which reinforces the same principles of password hygiene.<\/p>\n<\/section>\n\n<section class='section' id='how-to'>\n  <h2>How to protect yourself: 7 practical steps<\/h2>\n  <ol>\n    <li>Use a long passphrase rather than a short password.
