Use only characters from a predefined set of allowed characters.
Cannot be set at the same time as the characters option.
The distinguishable set contains only uppercase characters that are not easily confused: CDEHKMPRTUWXY012458. It can be useful if you need to print out a short string that you'd like users to read and type back in with minimal errors. For example, reading a code off of a screen that needs to be typed into a phone to connect two devices.
