Endpoint Security - Local Accounts

Creating and maintaining local admin accounts

Maintaining secure local access accounts can be a challenging prospect for MSPs. Learn how the RMM Suite allows MSPs to create accounts and change passwords on any frequency they desire without any manual effort.

The LAUSER Account

Back in 2019, a customer related an experience of when a VIP user at a major customer was in an airport lounge. The user needed to print their presentation and needed admin access to install the print driver. The WiFi was limited to http protocol access, which prevented the MSP from using their RMM to provide support. They had no choice but to provide the user with their internal use password. This required changing the password throughout that customer environment. We suggested that a commonly named account ("lauser") could be created and our automation could maintain and update the credentials on a weekly basis. We rolled that process into ITP and began deploying this account for our customers soon after.

A few years later, MSPs are looking to improve security and decide to use the LAUSER account for their local access. This led to an additional improvement in this component, allowing multiple accounts to be created using this process.

One of the unique security features of this process is that the password is generated based on using the date, time, and hostname, along with other logic, to seed the password generation logic. This ensures that the password is machine-specific and impossible to re-synthesize.

The RAUSER & CAUSER Accounts

The RMM Suite has long supported the use of per-client accounts for the MSP (RAUSER) and the customer (CAUSER), first via Managed Variables in Kaseya VSA and now via self-ciphering Cloud Script Variables on all RMM platforms. These accounts offer the flexibility of selecting the actual login ID, display name, and password. These credentials apply to groups of agents, whether an entire customer organization or specific location or department.

RMM Suite Account Management Tools

The RMM Suite continues to support multiple methods of local account management.

  • If the RAUSER (or CAUSER) Cloud Script Variable (CSV) is defined (both UserID and Password), the account will be created, added to the local administrators group, and the defined password will be set on the account. This happens automatically the first time that an agent checks in. These accounts can be updated at any time by updating the account password stored in the CSV and then executing the appropriate WIN-Local Account script on the RMM platform, targeting the endpoints where the account should be updated.
  • The LAUSER technology has been enhanced and migrated into our Daily Maintenance tool. Simply create a Weekly or Monthly task to run the LAUSER command. This will generate a long, complex password; create the account and add it to the Administrators group if necessary; then set the password. The password will be ciphered and written to the system registry, where it can be collected by the Daily Audit tool, deciphered, and pushed into the RMM or your documentation engine such as Hudu or IT Glue. You can define multiple tasks in Maintenance with the LAUSER command to create any number of local admin accounts with unique credentials. 
    • If no argument is defined, the account name "lauser" is targeted. This maintains the process we implemented several years earlier and allows this account to be given to the user as necessary. It may be appropriate to update the frequency of this account change.
    • If an argument is provided, it will be used as the account name. This argument should be a single word without spaces, following the usual guidelines for user account IDs.
