How do I find my device's UUID?

[AC Question]

I am looking over my LastPass account details and there are five "trusted devices" listed by their UUID. I have only two devices. I need to figure out which of these two is considered trusted and delete the other three. I cannot seem to find where it is listed on the device in any menu. Please advise.

Well - here's my non-technical way around it.
Set them both to "Disable".
Enable one - enter password.
If that doesn't work your other big long number is your UUID.
