User access is one of the most important parts of ERP security. Strong access controls help ensure employees can perform their responsibilities while reducing exposure to sensitive financial, customer, vendor, and operational data.
ACC helps customers review user access, security roles, MFA options, and single sign-on considerations for Acumatica, Sage 100, and related systems.
When access controls are overlooked, businesses can unintentionally create security gaps through excessive permissions, inactive accounts, weak passwords, or shared logins. A structured access management strategy helps reduce risk while improving accountability and visibility across the organization.
Multi-factor authentication (MFA) adds an extra layer of protection when users log into a system. Instead of relying only on a password, MFA requires an additional verification step, such as:
Even if a password becomes compromised, MFA helps prevent unauthorized access by requiring a second form of verification.
Passwords alone are no longer enough to protect business systems. Cybercriminals commonly target login credentials through phishing emails, password reuse, and automated attacks.
MFA significantly reduces the likelihood of unauthorized access by adding another checkpoint before a user can enter the system.
For ERP environments, MFA is especially important because these systems often contain:
ACC works with customers to review MFA availability and implementation options within their ERP and related applications.
Single sign-on (SSO) allows users to log into multiple connected systems using one secure identity provider and one set of credentials.
Instead of maintaining separate usernames and passwords across different applications, users authenticate once through a centralized login process.
Benefits of SSO can include:
SSO can also make it easier to disable access quickly when an employee leaves the organization.
Administrator accounts typically have elevated permissions that allow users to manage security settings, modify system configurations, and access highly sensitive information. Because of this, administrator accounts should receive additional protection and regular review.
Organizations should limit administrative privileges to only the users who genuinely require elevated access for their responsibilities. MFA should be enabled for all administrator accounts whenever possible, and shared administrative credentials should be avoided entirely.
Many organizations also benefit from separating standard user activity from administrative activity by using dedicated administrator accounts instead of performing routine work with elevated permissions.
Regular reviews of administrator access can help identify outdated privileges, unnecessary accounts, or lingering access for former employees and consultants.
User access requirements often change over time as employees move between departments, take on new responsibilities, or participate in temporary projects. Without periodic review, users can gradually accumulate permissions that are no longer necessary for their current role.
Regular role reviews help organizations confirm that employees only have access to the systems, reports, approvals, and operational functions required for their responsibilities. These reviews may include financial permissions, reporting visibility, approval workflows, inventory access, operational controls, administrative privileges, and integration-related permissions.
Maintaining properly aligned user roles helps reduce unnecessary exposure while improving accountability and operational visibility.
ACC assists customers with reviewing ERP security roles and helping align user access with real-world business responsibilities.
One of the most common security oversights is failing to remove access promptly after an employee leaves the organization. Inactive accounts can create unnecessary exposure, particularly when remote access, administrative privileges, or integration credentials remain active.
Organizations should establish a consistent offboarding process that includes disabling ERP access immediately upon separation, removing access to connected applications, revoking administrator permissions, and disabling remote access where applicable.
Depending on the environment, offboarding reviews may also include integration credentials, API access, VPN access, or connected authentication platforms tied to the employee account.
Promptly removing unused accounts helps strengthen overall access governance while reducing avoidable security risk.
Shared user accounts can create significant visibility and accountability challenges within an ERP environment. When multiple individuals use the same credentials, it becomes difficult to accurately track activity, investigate issues, or confirm who performed specific actions within the system.
Shared credentials also tend to create inconsistent password management practices and increase the likelihood that former employees or outside users may still know active login information long after access should have been removed.
Whenever possible, each employee should use their own individual login credentials. Unique user accounts improve audit visibility, simplify access management, strengthen accountability, and support more effective security monitoring across the organization.
User access and security settings should not be reviewed only once. Regular reviews help organizations identify outdated permissions, inactive accounts, and policy gaps before they become larger issues.
A common review schedule may include:
| Review Area | Recommended Frequency |
| User access reviews | Quarterly |
| Administrator access reviews | Quarterly |
| Former employee account checks | Ongoing |
| MFA verification | Annually or after major changes |
| Security role reviews | Annually |
| Password and authentication policy reviews | Annually |
Organizations with compliance requirements or higher security risks may require more frequent reviews.
ERP security is not only about technology. It also depends on consistent user management, strong authentication practices, and controlled access to sensitive business data.
ACC helps organizations evaluate user access structures, review security roles, discuss MFA and SSO options, and improve access management practices within Acumatica, Sage 100, and related business systems.
