Password length is limited to a maximum of 168 characters because this is the maximum length passwordmanster.com can load at once without showing "not responding" message. The lowest is 16 because the limit for a secure password is 4 lower case, 4 upper case, 4 numbers and 4 symbols, and 4*4 is 16. Triple click the item in the 'Copy' list and press ctrl + c or left click and copy and paste your password whenever you want.
