Windows PE on a virtual flash drive for some of the Windows imaging work that we do.I've used this for laptop/PC imaging, driver installs, Live CDs with various 'fixing' tools, as well as updating network switches and routers.

The drive supports AES encryption (but if you're booting from the drive, the time it takes to unlock it may get in the way of your being able to boot to it, such as on Surface laptops). It also emulates an optical disk drive (you select the ISO to 'load' using the on-device screen/keypad) for booting as well as up to 4 additional drives (appearing as memory sticks or USB-connected hard drives).

I use the iodd Mini (search Amazon for it), which has an M.2 SSD at the core (up to 1TB). There are certainly other methods to do this but it's relatively easy and safer than a text document in a (protected) network share, I guess. We mainly need it since we have to manage licenses in some web uis for programs from Adobe and autodesk for example so it allows us to use generated passwords whitout having to exchange said passwords all the times since they can be hidden from some users. Not sure what feature you expect from a password manager but so far it seems to do the job for us. You can have 2fa by having their phone application so you don't have to use SMS texts which is apparently unsafe(r) than other 2fa methods so that's also a plus, I guess. Not sure about the pricing tho, my boss handles that. So far it seems to be fine and does what it should. So far it looks to work well, you can create different groups and assign individual users to those groups and decide if they can see passwords or not for example.

We only started using it recently and are still working on importing all our accounts.
