To improve security in MS
Excel and protect your workbooks from unnecessary modification by
unauthorized users, Microsoft has introduced advanced
password-protection. You can secure your whole workbook or some
specific elements in your workbook by applying a password. Only
authenticated users will have the right to make changes to the
workbook or its individual elements. You can apply two different
types of passwords to an Excel workbook: 'Password To Open' and
'Password To Modify'.
The 'Password To
Open' feature can be used to prevent the illicit or unwanted users
from opening the Excel workbook. This feature uses any of the
standard encryption methods to secure data in the file. You
can do this via Save As>>Tools>>Security Options and an
existing one Main Menu>>Tools>>Options>>Security.
Additionally, if you want to keep
other users from changing the structure of your Excel workbook, you
can use the 'Password To Modify' feature. With this feature, you can
define a guideline for others and then, they need to follow this
guideline for modifying the content or formatting of your workbook.
To do so,
go to Tools and choose Protect Document or Unprotect Document.
However, if there are a hell lot of
passwords, there is always a high risk of losing these passwords.
These passwords will keep on clogging up your brain and consequently,
you forget them when trying to unlock your password-protected Excel
workbooks. At this stage, you need to take help of professional MS
Excel password recovery software.
Let
me tell you my example. I joined at a new office last week. The
person who left the organization had protected some of his Excel
files. He didn't tell the passwords to anyone. However, I had to use
those files in order to start my work. But, I found out that I cannot
even open some of the important files. I immediately narrated the
whole situation to my Team Lead and he recommended me to contact the
system administration department. I contacted them and told them this
problem. To recover Excel
password,
they installed a password recovery software on my computer and it was
all over in just a few clicks. All the passwords were saved in the
text document at a specified location in my system.
An
efficient Excel password recovery software can easily recover both:
'password to open' and 'password to modify' set to your Excel
workbook. These software use Brute-Force attack mechanism to give you
the recovered password with 100% accuracy. The software which I used
provided me various options to narrow down the Excel password search.
