Two-factor authentication

About two-factor authentication

To enable two-factor authentication for yourself, permission to access Setup → My Info. To enable two-factor authentication for you organization, you must be an Administrator.

Two-factor authentication (2FA) is a security process in which a second level of authentication is added to the account login credentials. Both factors of authentication must be used and must be correct in order to establish the person's identity beyond doubt. The two factors may include:

  • Something that the user possesses, such as a token, a card, a key, etc.
  • Something that the user knows, such as a username, password, PIN, etc.
  • Something that is inseparable from the user, such as a fingerprint, iris, voice, etc.


In Datto RMM , 2FA requires login credentials (username and password) and a one-time password (OTP) issued by an OTP token application.

  • To enable two-factor authentication for yourself, you must have at least View permission for the Setup → My Info tab.
  • A 2FA-token-generating application such as Google Authenticator (Android & iOS), Authy (Android & iOS), or HDE OTP (iOS) must be installed on your smartphone or tablet.
  • You should have a valid phone number set up that can receive SMS messages. Refer to Edit your user details. The phone number will be used for recovery purposes or when disabling 2FA on a single user account when logging in.

Ensure that you use the correct +XX country code format.
For example, a UK phone number entered as +447407123456 uses the correct format and will receive codes. The same number entered as 00447407123456 uses an incorrect format and will not receive codes.

We strongly recommend that you assign Administrator access to more than one user in the Datto RMM account. This is to ensure recovery, should there be an issue authenticating during the initial configuration or if the authenticating device encounters a problem or is lost.
