Paxton's Net2 access control system is one of the most widely deployed solutions for managing building security, from small offices to multi‑door facilities with up to 1,000 doors and 50,000 users. At the heart of Net2 lies a Microsoft SQL database that stores every critical piece of system information—user credentials, cardholder data, door permissions, event logs, and access schedules. Understanding how to manage, secure, and recover the passwords associated with this SQL database is essential for any system administrator or security professional.
Before we decode the password, we need to understand the architecture. Paxton Net2 (versions prior to Net2 Plus) relies on a back-end database to store all access control data: user credentials, access levels, time zones, door settings, and event logs. By default, Net2 uses one of two database engines:
Altering the SQL database password for Paxton Net2 is not as simple as changing a password in SQL Server Management Studio (SSMS). If you change the password in SQL Server without updating Net2, the Net2 Server service will fail to connect, crashing your entire access control system.

Paxton stores passwords , not on the access control units themselves (ACUs). The code is obfuscated “to prevent decryption as much as is possible,” though Paxton also acknowledges that “with enough time and patience, any system can be hacked”.
Newer versions of Net2 have introduced "Secure Mode." Enabling this restricts communication ports to the database and locks down specific API endpoints. By default, newer Net2 installations should have the API disabled, and Secure Mode should be turned on immediately. Paxton's Net2 access control system is one of
Net2 typically uses to host its data. During installation, the software creates a database instance (often named PAXTON ) and configures specific service accounts to interact with it.

In both cases, the database is protected by authentication credentials. This is where the concept of the exclusive password enters the conversation.
in certain security contexts, Paxton does not officially publish a static "exclusive" password for the SQL Recovering Database Strings
With write access to the SQL database, a malicious actor could theoretically insert a new token number or alter user permissions. This allows them to grant unauthorized access to a physical building without triggering an immediate alert on the Net2 monitoring console. Lateral Movement
An attacker who discovers the Net2 SQL password can connect to the database remotely or locally via SSMS. Once connected, they can view sensitive employee data, including full names, department details, card/fob token numbers, and historical access logs. Access Control Manipulation
