I have a SanDisk 2TB extreme portable SSD. It worked fine for several months. Now it doesn't appear in finder, and disk utility shows it, but first aid tells me it can't be unlocked. I tried other ports, and another mac.
I contacted San Disk and they told me the problem is the disc is password protected and that it is an apple problem.
Any help would be appreciated.

if the drive is password protected, are you using any of SanDisk's preloaded software on the drive (or installed such software yourself) that supposedly makes the drive "Mac ready"? or any software from SanDisk to password protect the drive? if yes, that could be the cause of your issue. when you use software from just about any manufacturer for their storage device you run the risk of that same software not being compatible with macOS updates / upgrades. it can cause the software to stop working. at best this will cause you a headache. at worst it can render your data inaccessible. it is always best to use disk utility to erase and format a drive before use to remove any preloaded software.
please see Erase and reformat a storage device in Disk Utility on Mac - Apple Support.
if you are using such software, i think your options are somewhat limited.
you may want to contact SanDisk and see if there is an update for their software.
alternatively, if you have a backup you can revert your macOS to the version of macOS that the drive was working on and transfer your data to another storage device and then erase and format the SanDisk device before putting it back into service.
