PRTG Manual: Use Multifactor Authentication with PRTG Hosted Monitor

You can use multifactor authentication with PRTG Hosted Monitor. In combination with an authenticator app that supports the Time-based One-time Password algorithm (TOTP), such as Google Authenticator, you can make your PRTG Hosted Monitor instance even more secure.

Multifactor authentication is only available in PRTG Hosted Monitor. For more information, see the Knowledge Base: How to integrate Microsoft Entra ID into PRTG Hosted Monitor?
