### Changing the default SYSDBA password

 Created by Russ Hartle, Modified on Tue, 11 Nov, 2025 at 10:25 AM by Russ Hartle

Generally, the SYSDBA password will be changed through the RMS installer/patch. However, if you need to manually change the SYSDBA password from its default “masterkey”, please follow the steps below:

Open a new CMD window and navigate to the bin directory of the Firebird installation. In this example the bin directory is located: “C:\\Program Files\\Firebird\\Firebird\_2\_1\\bin”

Type the following command (without quotes): “gsec -user sysdba -password masterkey” and then press the “Enter” key to start the GSEC Utility

Type the following command (without quotes): “modify sysdba -pw j316fgsl” and then press the “Enter” key to change the default Firebird password to “j316fgsl”.
