Disable SMS for MFA Without the Risk
Reduce exposure to SMS-based MFA risks by avoiding phone-based authentication and using stronger methods like authenticator apps or security keys in NinjaOne.
Key Benefits of Disabling SMS for MFA
Reduce MFA Security Risks
Avoid relying on SMS-based authentication, which is more vulnerable to phishing and SIM swap attacks, and strengthen access security by using more reliable authentication methods.
Enable Faster, More Convenient Logins
Use authentication methods like biometrics, authenticator apps, or security keys to make logins quicker and more seamless, offering a secure and flexible experience across different access scenarios.
Avoid SMS-Related Delays
Stop depending on text messages that can be delayed, blocked, or unavailable, and use more reliable authentication methods that work consistently across devices.
What does this product do?
Authenticator App (TOTP Codes)
Set up an authenticator app like Google Authenticator or Authy to generate secure login codes, using a quick QR code setup directly in the platform.
Hardware Security Keys
Log in using a physical security key or built-in device features, offering a fast and secure way to access the platform without entering codes.
Single Sign-On (SSO) Support
Sign in through an external provider using SSO, allowing you to manage access in one place and apply additional security settings outside of NinjaOne.
(Optional) SMS Authentication
SMS can be added as a login method, but it’s optional and marked as the least secure, making it easy to avoid and rely on stronger options instead.
Common Use Cases for Avoiding SMS MFA
Switching away from SMS-based authentication helps improve both security and user experience. Here are a few real-world scenarios where avoiding SMS makes a clear impact:
A Team Needs to Reduce Security Risks
When an organization is strengthening its security posture, relying on SMS can become a concern due to phishing and SIM swap risks. In these cases, IT teams move users to more secure methods like authenticator apps or security keys to better protect access.
Users Want a More Seamless Login Experience
In day-to-day operations, entering SMS codes can slow users down, especially when they need to switch between devices. Teams looking to simplify access often adopt methods like built-in device authentication or apps to create a more consistent and seamless login experience.
Login Issues Caused by Delayed SMS Codes
When users experience delays or failures in receiving SMS codes, it can disrupt access and create frustration. To avoid these issues, organizations switch to more reliable authentication methods that don’t depend on mobile networks.
Stop Relying on SMS for MFA
Stronger authentication doesn’t have to be complicated. By moving away from SMS and using more reliable MFA methods, you can improve security and make access easier for your users at the same time.
- Strengthen access security with better MFA methods
- Simplify logins without relying on text messages
- Avoid delays and issues caused by SMS verification

Disable SMS for MFA FAQs
How do I disable SMS as a multi-factor authentication method in NinjaOne?
In NinjaOne, SMS is not enabled by default and must be manually configured by adding a phone number. To avoid using SMS, simply do not set it up and instead configure stronger authentication methods like an authenticator app or hardware security key in the user’s security settings.
Why should SMS-based MFA be disabled?
Because SMS is easier to break than other methods. Attackers can trick users or take control of phone numbers to get access codes, while stronger options like apps or security keys are harder to bypass.
What are the security risks of using SMS for MFA?
SMS can be intercepted or redirected, especially in cases like SIM swap attacks or phishing. This means someone else could receive your login code and gain access without your permission.
What alternative MFA methods are recommended?
Authenticator apps and hardware security keys are recommended because they are more secure and don’t rely on text messages. In NinjaOne, users can set up options like authenticator apps (such as Google Authenticator or Authy), hardware security keys, and Single Sign-On (SSO) for a more secure and reliable login experience.
Can I disable SMS MFA for all users or only specific accounts?
In NinjaOne, SMS is configured at the user level, meaning each user can choose whether to set it up. To avoid SMS across your organization, users should not configure it and instead use stronger authentication methods.
Will users be required to set up another MFA method after disabling SMS?
Yes, users will need to have at least one MFA method configured to access NinjaOne, so they should set up an alternative like an authenticator app or security key if SMS is not used.
Is there any benefit to enabling SMS MFA in NinjaOne?
SMS can be useful as a backup MFA method in case other options, like authenticator apps or security keys, are unavailable. However, since it is considered the least secure method, it’s recommended to use it only as a secondary option rather than a primary authentication method.
Does avoiding SMS MFA affect existing authentication workflows?
No, avoiding SMS does not disrupt authentication workflows. Users can continue to log in using other configured methods like authenticator apps, security keys, or SSO without any impact on access.
How does NinjaOne support more secure MFA options?
NinjaOne supports secure MFA options by allowing users to choose stronger authentication methods like authenticator apps, hardware security keys, and SSO. It also clearly identifies SMS as the least secure option, helping guide users toward safer choices when setting up their authentication.
