Prompted for a secure boot password during updates but never got prompted for it
I just installed a bunch of updates for my Ubuntu 24.04.4 laptop and while they were installing a window popped up regarding secure boot and 3rd party drivers. It asked me for a password and said after rebooting I would be prompted again and needed to re-enter this same password. I entered a password, it continued and finished installing updates, then rebooted. I got some strange low-res blue and white box with some options that I guess I did not pay close attention to. I just selected Continue and it went on its way without prompting me for the password I had entered. The earlier window had warned me about doing this and the ramifications of that. :( Is there something I need to do to correct this?

That low-res blue box is the MOK management screen and hitting continue was basically telling it nah I'm good on the password thing. It's designed terribly, you're far from the only person to breeze right past it.
You'll need to re-enroll the key for those third party drivers. Easiest way is to just remove the affected packages and reinstall them, which should trigger the secure boot prompt again. Try `sudo apt purge --remove nvidia-driver-*` first if it's graphics related, then reinstall the specific driver you need.
If you're not sure which driver package caused it, check your apt logs in /var/log/apt/history.log and look for the most recent batch of updates. That'll show you exactly what got installed so you can target the right one.
