Multi-Factor Authentication (MFA) helps enhance account security by requiring a second form of verification— an email-based One-Time Passcode (OTP) or SMS OTP— in addition to a password. When enabled, users are prompted to supply the additional OTP. This feature provides an extra layer of protection for accounts with administrator roles, safeguarding sensitive data and organizational settings.
Note
The Samsara dashboard logs an event when MFA is enabled. You can track these changes in the Activity Log.
Refer to the following topics for more information on MFA:
All users with highly-privileged access must sign in using Multi-Factor Authentication (MFA). This includes:
-
Users assigned pre-built system roles such as Full Admin, Standard Admin, Read-Only Admin, and Organizational Admin in organizations that do not use SSO.
-
Users in custom roles that provide elevated access permissions—such as those managing users, roles, billing, or security settings.
The following table outlines the custom permissions that constitute admin-level access in the Samsara platform. Users assigned any of the listed permissions will be required to use MFA.

As of October 7, 2025 MFA is required and once enabled, it cannot be disabled.
Multi-factor authentication (MFA) is one of the most effective ways to prevent unauthorized access, especially in situations where a password might be lost, stolen, or shared. With a second layer of verification, MFA helps safeguard your data, reduce the risk of operational disruptions, and ensure compliance with industry standards.
These changes are part of Samsara’s broader commitment to delivering enterprise-grade security, aligning with industry best practices, and maintaining your trust as your operational technology partner.
To enable MFA, you must have a Full Admin role or have a custom role with the Security Policies user permission Update Security Policies enabled.

After successful credential entry and MFA setup, you’ll be prompted to enter a six-digit One-Time Passcode (OTP) sent to either your registered email address from
<noreply@samsara.com>, or through SMS. If you'd like to receive your OTP through SMS, see Add SMS OTP as an MFA Option for more information.The code is valid for 10 minutes.
-
If you opted to receive OTP through SMS, check your text messages for the OTP. Otherwise, check your inbox for the OTP email. If you don’t receive it, check your spam folder.
Tip
When you locate the email, mark the email as not spam to ensure future OTPs are delivered to your inbox.
-
Enter the OTP on the sign in screen. If the code expires, select to receive a new OTP.
You can use SMS OTP as an MFA option if you have a verified phone number and selected that delivery method.
If you'd like to use SMS OTP as an MFA option, perform the following workflow:
-
Select the icon for your user menu and select Profile to access your user profile.
-
Click Edit.
-
Confirm your phone number is correct.
If you don't have a phone number in your profile, add one, and then Save.
-

You will have the option to receive the MFA code through SMS during your next sign-in attempt.
