Microsoft's Policy Regarding Missing or Invalid Passwords
ID: Q189126
|
The information in this article applies to:
-
All Windows, Windows NT, Macintosh, and MS-DOS versions of the following Microsoft Office family programs:
-
Microsoft Mail
-
Microsoft Word
-
Microsoft Excel
-
Microsoft Access
-
Microsoft Outlook
-
Microsoft Project
-
Microsoft Exchange
-
Microsoft PowerPoint
-
All other Microsoft programs in which passwords may be applied to files and features within files
SUMMARY
In many of the programs listed at the beginning of this article, you can
prevent unauthorized users from opening a file by applying a password to
the file. When you attempt to open the file, the program requests the
password; if you do not enter the correct password, you are unable to open
the file.
Also, there are certain features within these programs to which you can
apply passwords. For example, you can password-protect a project in the
Visual Basic Editor in the programs included in Microsoft Office 97 and
Microsoft Office 98 Macintosh Edition.
This article explains Microsoft's policy regarding missing or invalid
passwords.
MORE INFORMATION
Microsoft has added password protection to the programs listed at the
beginning of this article so that you can prevent unauthorized access to
important information. For this reason, if you are unable to access
information because you do not know the correct password,
MICROSOFT ENGINEERS CANNOT ASSIST, UNDER ANY CIRCUMSTANCES, IN THE
BREAKING OF PASSWORDS APPLIED TO FILES AND FEATURES WITHIN MICROSOFT
PROGRAMS.
It is technically not possible for Microsoft engineers to break the
password on a password-protected file or feature within a Microsoft
program. The password-protection systems built into Microsoft programs
are designed to be unbreakable; there would be no point in including a
password-protection system that could be broken.
If you are unable to open a file that is protected with a password, follow
the steps in the "If Your Password Isn't Working" section, below. If you
are still unable to open the file, Microsoft engineers cannot assist you.
However, you may be able to obtain assistance from a third-party password
breaker.
Note that you may want to read the remainder of this article for
suggestions about how to effectively use passwords in the future.
If Your Password Isn't Working
In all of the programs listed at the beginning of this article, passwords
applied to files are case-sensitive. For example, the following passwords
are all different
hello
Hello
HELLO
because the letters are in different cases in each password.
A common problem that occurs when you enter a password is to use the
incorrect case for one or more of the letters in the password. If your
password is not accepted, try the following:
- Press the CAPS LOCK key, and then enter the password again. If you
remember holding down the SHIFT key when you originally applied the
password, make sure you press the SHIFT key as appropriate, even if
the CAPS LOCK key has been pressed.
- Enter the password using different combinations of upper- and lower-
case characters. For example, if the password "hello" is not working,
try "Hello".
- If someone else provided you with the file, check with that person to
see if he or she still has the password.
If none of these suggestions work, you may want to take a look at the
following articles in the Microsoft Knowledge Base:

Third-Party Password Breakers
There are third-party companies who claim to be able to break passwords
that have been applied to files and features used by Microsoft programs.
For legal reasons, Microsoft cannot recommend or endorse any of these
companies. If you require assistance in the breaking of a password, you
may, at your own risk, locate and contact a third-party company who can
provide you with such assistance.
Protecting Yourself Against Password Loss
If you are finally able to open the file, you may want to apply one or more
of the following suggestions to make sure that the problem does not occur
again:
- Change your passwords so that they are easier to remember. For example, "ty65dr58geT" is hard to remember. "Pyramid5" is easy to remember, but still a valid password.
- If you have a secure location, such as a safe or a safety deposit box, you may want to store a written copy of your passwords there.
- Also, you can save unprotected copies of your files to a floppy disk,
removable hard disk, or other external storage device, and then store
the disk in a secure location.
Password Recommendations
When you apply passwords to files or features within Microsoft programs,
you may want to use one or more of the following suggestions to increase
the security of your files:
- Don't use words that are in the dictionary as passwords. Instead, use
two or more words joined together. Or, use a combination of words and
numbers. For example, instead of "dog", use "dogcat" or "dog5".
- Don't use personal information, such as names of family members or
pets, your date of birth, social security number, or other similar
information as part of a password. Since such information may be
public, you should not use it in a password, even in combination with
other characters.
- Use a combination of upper- and lower-case letters in your passwords.
Since passwords are case-sensitive, you may be able to prevent a break-
in if someone else hears, as opposed to sees, your password.
- Passwords should usually be at least six characters in length.
- Don't use obvious passwords like "password", "guest", "user", or
"admin".
Employees and Passwords
A problem occurs when either of the following are true:
- One of your employees left your company. The employee used a number of files, some of which were/are password-protected. Now, the employee is
gone, and you do not know the passwords for the files.
-or-
- Prior to their departure/dismissal from your company, a disgruntled
employee applied passwords to some of your files. Now, you are unable
to open the files, and the employee refuses to reveal the passwords to
you.
If either of these problems occur, remember that Microsoft engineers cannot
assist you in the breaking of passwords applied to the files.
To help prevent these problems from occurring:
- When employees leave your company, make sure that they either remove
all passwords from their files or provide you with a complete list of
all of their passwords. Also, make sure that you maintain correct
contact information for the employees, so that you can get in touch with
them should a password not work correctly.
- To protect your files from deliberate, malicious password application,
make sure that you keep backup copies of all of your files. You should
make backup copies of critical files on a daily basis; other files may
be backed up as required.
- If you store your files on a Windows NT server, you can quickly suspend
an employee's access to the server, thereby preventing the employee from
making further changes to files. You can also prevent users from
accessing files to which they do not need access.
A Note Regarding Microsoft PowerPoint
In Microsoft PowerPoint, you cannot apply a password to a presentation
file; this feature does not exist in Microsoft PowerPoint. However, in
later versions of Microsoft PowerPoint, you can still apply a password to a
Visual Basic project.
