Lost AS400 Password

10 pts.
AS/400 security
We have lost our AS400 password, and we don't have a service contract. Any ideas where we should start or were we can go for help.

Thanks. We'll let you know when a new response is added.

with the midrange AS/400 systems the IBM service engineers have system disks that they can use to reset the Security Officer and Systems Manager passwords. That is the only way I know to do it.


To get useful help, some clarification is needed. Simply stated, which password did you lose? There are numerous passwords possible. Did you lose your user profile password? …the QSECOFR profile password? …some different profile password? …aDST profile password? (Which one? QSECOFR? …a different DST profile password?) …the ‘system’ password? (Why do you need the ‘system’ password?)

Different passwords have different recovery possibilities.

    I believe buddy is right, especially if no is left who knows their password that has enough access rights to reset the SECOFR/SECOPR (etc) account's password. Other than that, the only way I know is to call IBM out or a consultant out (assuming they will do time and materials work) or try to see if you can sweet talk a IBM service rep into helping you without a contract.

    Hi, You might be able to start DST (dedicated service tools) from an IPL and with a bit of luck you will still have the original service tools users and passwords :- http://publib.boulder.ibm.com/infocenter/systems/scope/i5os/index.jsp Then you should be able to sign-on as a service tools user and reset passwords for other profiles.

    If you don't have your DST password you can set the password to default (QSECOFR) using the command: CHGDSTPWD PASSWORD(*DEFAULT) this will set the DST QSECOFR passowrd to QSECOFR (case sensitive). You can then do a manual IPL and sign on to DST and you will have to change the password again. There is one further method to get QSECOFR poassword but you need to be fairly desparate as it means doing a full system reload. If you do this you will originally sign on with no password and then you can reset QSECOFR. Whichever way you go you should create a second profile with QSECOFR authority so you don't get caught like thbis again.

    If you can get into DST from Manual Mode try this Select option 6 (Service Tools Security Data) from the Work with DST Environment menu. Select option 1 (Reset Operating System Default Password) from the menu that appears, and follow the directions to reset the QSECOFR password. After executing this option, the QSECOFR user profile password will be reset to its default value of QSECOFR for this IPL only. Exit back to the Use Dedicated Service Tools menu, and select option 1 to IPL your system. When the system comes up, change the QSECOFR user profile to *ENABLED (if it's currently set to *DISABLED), and be sure to change QSECOFR's password to another password that is harder to crack. The default password, QSECOFR, is well-publicized on the Internet, and it will be the first password a cracker tries as he attempts to hack your system. It's also important to change your password immediately because some IBM documentation on this technique specifies that the system default password reset may only last for this one iSeries or AS/400 IPL. Reset your OS/400 IPL options back to normal mode. This is the procedure I used to test resetting the QSECOFR password under OS/400 V5R1. For OS/400 V4R5 machines, the procedure is similar but the options inside the Work with DST Environment menu are different. With V4R5, you would select option 3 (DST User Profiles) and Option 4 (Reset System Default Password) in steps 4 and 5. For earlier OS/400 releases, you may find that these options are also slightly different. Also you should alwasy have a backup User Profile with QSECOFR Authorities for just an occasion then you can sign on with this profile and chgusrprf qsecofr to renable or change password....Rick
