I can't create a password shorter than 6 digits
Remove the 6-digit requirement for a password. I need to be able to do a 4-digit password. I tried the workaround in the registry but it's not working. I am not sure why Adobe feels the need to set this requirement when it's not their document that is being protected.
@Adobe, for additional details about this specific Bug/Feature request, please see:
Why isn't there an Acrobat Setting to control how many characters are required for .pdf passwords?
Please allow users to decide what level of security they feel comfortable with.
Why do paying users need to fiddle with complex "workarounds", which no longer work?
