another type of characters to hide the token code

[OmlineEditor]

Is it possible to add an option to select a symbol to hide the token code in the settings? now there are only circles. is it possible to add bold minus symbols as in the application FreeOTP+?
it improves perception and helps people who have switched from another application feel better.
you can add a square, minus, or any other big character the user wants. It's simple, make it possible for the user to choose the symbol they like.

Thanks for the suggestion, but we're happy with the way this currently looks (still considering #672 though), so I don't think we'll be adding an option for this. We also want to keep the number of unnecessary customization options to a minimum.
