1. An Information Handling System (IHS) comprising:
a keyboard and/or keypad;
a display;
a processor coupled to the keyboard and/or keypad and the display; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the processor to:
initiate a password input session;
create a random transformation algorithm (RTA) that defines a transformation of an input character sequence to a transformed character sequence different from the input character sequence;
instruct a user of the IHS to apply the RTA to entry of a character sequence of the password by changing an input character sequence of the password to a transformed character sequence of the password, wherein instruct the user comprises communicate RTA instructions to the user via a third party device;
accept from the user entry of the transformed character sequence of the password via the keyboard and/or keypad; and
reverse transformation of the user entry of the character sequence in accordance with the RTA to logically arrive at the password.
