1. A computer-implemented method comprising:
a computer processor determining a quantity of consecutive unsuccessful attempts to access a targeted item protected by a current password;
responsive to the quantity of consecutive unsuccessful attempts to access the targeted item exceeding a predefined threshold, the computer processor selecting a new password in a sequential order from a set of new passwords, wherein a length of the selected new password exceeds a length of a previous new password and the selected new password is based on a more complex set of password generation rules than the current password;
the computer processor changing the current password of the targeted item to the new password; and
the computer processor sending an encrypted message regarding the new password to a user associated with the targeted item.
