Variable Elements (cont.)

• Variable elements can be used to differentiate between classes of access

• For example, using the same formula for super-user and normal-user access on the same system may result in passwords that have only minor differences

• Adding a variable element helps to mitigate this similarity. By adding the characters ‘0:’ (super-user) or ‘1:’ (normal-user) to the beginning of the formula, we can increase complexity and identify class of access:

• <0|1>:<u>@<h>.<d>;
