Full Discussion: Show Asterisks when changing Password
Top Forums UNIX for Advanced & Expert Users Show Asterisks when changing Password Post 303002797 by Corona688 on Friday 1st of September 2017 12:34:40 PM
Old 09-01-2017
The UNIX login / password system is called PAM, or shadow (part of PAM). Open source PAM actually used to have this feature (GETPASS_ASTERISK) but it was removed for security reasons sometime 2006-ish. It prevents people from guessing your password's length - same reason web browsers show the wrong number of asterisks on autofill.
