Password Management?

I was curious how others are keeping track of all their admin passwords.
With all of the SOX requirements and the mandate that we change passwords on
a frequent and consistent basis, I'm now having to keep up with multiple
(complex) passwords for my iSeries and other servers, and my poor little
brain's memory just isn't what it used to be. I have a local file that I use
and is protected from others using it, but I worry about losing it, or it
being compromised. Not to mention losing access to QSECOFR and/or my own
password, which are the only *SECOFR profiles on the system. If you would
rather reply off-list, please feel free to send directly to me email.
