As of May 28th, MongoDB's Management Service (MMS) requires Two-Factor Authentication (2FA) for all users, adding a layer of security by requiring both a password and a physical item to prove identity. Users can receive 2FA codes through Google Authenticator on their smartphone, text messages, or voice calls to their cell phone, with recovery codes available as an alternative when access to these methods is unavailable. While this requires slightly more work, the added security benefits make it a worthwhile investment for MMS users.
