Create a separate article for this one since it's usually an important security topic and deserves its own page. It should cover:

• What 2FA is

• Benefits of enabling 2FA

• How to set up an authenticator app

• Backup recovery codes

• Disabling or resetting 2FA

• Troubleshooting login issues after enabling 2FA

This structure matches what users expect from SaaS help centers like Intercom, HubSpot, Zendesk, and Crisp.
