<h3>Password Manager</h3>
|
|
|
|
<p>Password Manager preferences allow you to</p>
|
|
|
|
<ul>
|
|
<li><strong>Remember passwords:</strong> Select this checkbox to turn
|
|
Password Manager on, so that it asks to store your user names and passwords
|
|
at appropriate times and enters them for you automatically when
|
|
they're requested. To turn off Password Manager, deselect the same
|
|
checkbox.</li>
|
|
<li><strong>Manage Stored Passwords:</strong> Click this button to manage
|
|
information about your stored passwords and the sites whose user names and
|
|
passwords you don't want to be stored.</li>
|
|
</ul>
|
|
|
|
<p>For detailed information about using Password Manager, including how to
|
|
override it for individual sites and how to view and manage stored passwords,

<h3 id="encrypting_versus_obscuring">Encrypting Versus Obscuring</h3>
|
|
|
|
<p>If you use Password Manager or Form Manager to save passwords and personal
|
|
data, this sensitive information is stored on your computer in a file
|
|
that's difficult, but not impossible, for an intruder to read. This way
|
|
of storing information is sometimes described as <q>obscuring</q>. This
|
|
is the default setting that applies to information stored by Password Manager
|
|
or Form Manager.</p>
|
|
|
|
<p>For improved protection, you may choose to protect the file with encryption.
|
|
Encryption makes it more difficult (but again, not impossible) for an
|
|
unauthorized person to view your stored sensitive information.</p>
|
|
|
|
<ul>
|
|
<li><strong>Use encryption when storing sensitive data:</strong> Select this
|
|
checkbox to turn on encryption, or deselect it to turn off encryption.</li>
|
|
</ul>
|
|
|
|
<p>If you have not previously set a
|
|
<a href="glossary.xhtml#master_password">master password</a>, you will be
|
|
asked to create one. To do so, follow the instructions as they appear on your
|
|
screen.</p>
|
|
|
|
<p>Using encryption versus obscuring for stored sensitive data is a tradeoff
|
|
between improved security and convenience:</p>
|
|
|
|
<ul>
|
|
<li>If you use encryption, you will need to enter a master password
|
|
periodically, which can be inconvenient. (For information about controlling
|
|
how often it is requested, see the discussion of the Master Password
|
|
timeout at
|
|
<a href="#master_passwords">Privacy &
|
|
Security Preferences - Master Passwords</a>.)</li>
|
|
<li>If you use obscuring, you may not have to set a master password at all
|
|
(unless you're using certificates for identification purposes), but it
|
|
may be easier for a stranger who has access to your computer to steal your
|
|
passwords.</li>
|
|
</ul>

|
|
|
|
<p>This section describes how to use Password Manager dialog box to control
|
|
your stored passwords. If you are not already viewing it, follow these
|
|
steps:</p>
|
|
|
|
<ol>
|
|
<li>Open the <span class="mac">&brandShortName;</span>
|
|
<span class="noMac">Edit</span> menu and choose Preferences.</li>
|
|
<li>Under the Privacy & Security category, click Passwords. (If no
|
|
subcategories are visible, double-click Privacy & Security to expand
|
|
the list.)</li>
|
|
<li>Click Manage Stored Passwords.</li>
|
|
</ol>
|
|
|
|
<p>Alternatively, open the Tools menu, choose Password manager, and then choose
|
|
Manage Stored Passwords from the submenu.</p>
|
|
|
|
<p>The Password Manager has two tabs:</p>
|
|
|
|
<ol>
|
|
<li><strong>Passwords Saved:</strong> Click this tab to view the list of
|
|
sites for which Password Manager has saved your user name and
|
|
password—that is, the sites for which you selected <q>Yes</q>
|
|
in response to Password Manager's request to store logon
|
|
information.
|
|
|
|
<p>The second column shows the user name for each site. If the password is
|
|
stored in encrypted form, <q>(encrypted)</q> appears after the user
|
|
name.</p>
|
|
|
|
<p>By default, stored passwords are not displayed.</p>
|
|
|
|
<ul>
|
|
<li>To see the list of stored passwords, click Show Passwords and confirm
|
|
your choice.</li>
|
|
<li>To hide the passwords, click Hide Passwords.</li>
|
|
</ul>
|
|
|
|
<p>If you remove an entry from the list, the stored user name and password
|
|
will be discarded, and you will need to log in manually the next time you
|
|
visit that site.</p>
|
|
</li>
|
|
<li><strong>Passwords Never Saved:</strong> Click this tab to view the list
|
|
of sites for which you selected <q>Never for this site</q> in response
|
|
to Password Manager's request to store logon information.
|
|
|
|
<p>If a site is included on this list, you will always have to type in your
|
|
user name and password manually when you log onto the site.</p>
|
|
|
|
<p>If you remove an entry from this list, Password Manager will again ask
|
|
you, the next time you log onto the site, whether to store your user name
|
|
and password.</p>
|
|
</li>
|
|
</ol>
|
|
|
|
<p>Regardless of which tab you are viewing, you can remove entries from the
|
|
list as follows:</p>
|
|
|
|
<ul>
|
|
<li><strong>Remove:</strong> Select one or more entries that you want to
|
|
remove, then click Remove.</li>
|
|
<li><strong>Remove All:</strong> Click this button to remove all the entries
|
|
listed in the tab you are viewing.</li>

<h3 id="change_master_passwords">Change Master Password</h3>
|
|
|
|
<p>A master password protects a security device, which is a software or
|
|
hardware device that stores sensitive information associated with your
|
|
identity, such as keys or certificates.</p>
|
|
|
|
<p>For example, the browser has a built-in Software Security Device, and you
|
|
can also use external security devices, such as smart cards, if your computer
|
|
is configured to use them.</p>
|
|
|
|
<p>The master password for the browser's built-in Software Security Device
|
|
also protects stored sensitive information such as email passwords, website
|
|
passwords, and other data stored by the Password Manager and Form
|
|
Manager.</p>
|
|
|
|
<ul>
|
|
<li><strong>Change Password:</strong> Click this button to set or change any
|
|
of your master passwords. For information about using the Change Master
|
|
Password dialog box that appears when you click this button, see
|
|
<a href="#change_master_password">Change Master Password</a>.</li>
|
|
</ul>
|
|
|
|
<h3 id="master_password_timeout">Master Password Timeout</h3>
|
|
|
|
<p>After you first set a new master password, you will be asked to enter it
|
|
only when the newly launched browser first needs it to access personal
|
|
information, such as a user name and password, saved form data, or personal
|
|
certificates.</p>
|
|
|
|
<p>You can control how often the browser requests your master password:</p>
|
|
|
|
<ul>
|
|
<li><strong>The first time it is needed.</strong> This setting
|
|
(selected by default) causes the browser to request your master password
|
|
only the first time it needs access to the private key database after
|
|
launching. The browser will not request the master password again until
|
|
after you exit and relaunch it. This setting provides the lowest level of
|
|
protection.</li>
|
|
<li><strong>Every time it is needed.</strong> This setting ensures that the
|
|
browser will never access your saved personal information without first
|
|
requesting your master password. This setting provides the highest level of
|
|
protection.</li>
|
|
<li><strong>If it has not been used for __ minutes or longer.</strong> This
|
|
setting causes the browser to request your master password if it needs to
|
|
access your personal information and the specified interval has elapsed
|
|
since the last time it did so.</li>
|
|
</ul>
|
|
|
|
<h3>Reset Master Password</h3>
|
|
|
|
<p><strong>Warning:</strong> If you reset your master password, you will
|
|
permanently erase all the encrypted web passwords, email passwords, and form
|
|
data saved on your behalf by Password Manager and Form Manager. You will also
|
|
lose all your personal certificates associated with the
|
|
<a href="glossary.xhtml#software_security_device">Software
|
|
Security Device</a>.</p>
|
|
|
|
<p>Note that encrypted passwords and form data will be lost only if you have
|
|
turned on encryption for this stored information. For information about
|
|
turning encryption on or off, see
|
|
<a href="using_priv_help.xhtml#turning_encryption_on_and_off">Turning
|
|
Encryption On and Off</a>.</p>
|
|
|
|
<p>To change your master password rather than resetting it, click the Change
|
|
Password button in the Master Passwords preferences panel.</p>
|
|
|
|
<p>You must remember your old master password to change it with the Change
|
|
Password button.</p>
|
|
|
|
<p>If you are really sure that you want to reset your master password and
|
|
permanently erase all your encrypted personal information and
|
|
certificates:</p>
|
|
|
|
<ul>
|
|
<li><strong>Reset Master Password:</strong> Click this button to reset the
|
|
master password for the Software Security Device. For more information,
|
|
see <a href="#reset_master_password">Reset Master Password</a>.</li>
|

</ul>
|

|
<h2 id="change_master_password">Change Master Password</h2>

|
|
<li>Click Change Password.</li>
|
|
</ol>
|
|
|
|
<p>A master password protects a security device, which is a software or
|
|
hardware device that stores sensitive information associated with your
|
|
identity, such as keys or certificates.</p>
|
|
|
|
<p>For example, the browser has a built-in Software Security Device, and you
|
|
can also use external security devices, such as smart cards, if your computer
|
|
is configured to use them.</p>
|
|
|
|
<p>The master password for the browser's built-in Software Security Device
|
|
also protects your master key. Your master key is used to encrypt sensitive
|
|
information such as email passwords, website passwords, and other data stored
|
|
by the Password Manager and Form Manager.</p>
|
|
|
|
<p>You use the Change Master Password dialog box to provide the following
|
|
information:</p>
|
|
|
|
<ul>
|
|
<li><strong>Security Device:</strong> Each security device requires a
|
|
separate master password. For example, if you are using one or more smart
|
|
cards to store some of your certificates, you should set a separate master
|
|
password for each one. If more than one security device is available, a
|
|
drop-down list at the top of the Set Master Password dialog box allows you
|
|
to choose the device whose password you want to change.</li>
|
|
<li><strong>Current password:</strong> If you are changing an existing master
|
|
password, you must first type the current password. If you don't type
|
|
the current password correctly, you will see the message <q>You did not
|
|
enter the current correct Master Password</q> after you click OK. If this
|
|
happens, you must retype your current password.</li>
|
|
<li><strong>New password:</strong> Type your new password into this
|
|
field.</li>
|
|
<li><strong>New password (again):</strong> Type your new password again. If
|
|
you don't type it the second time exactly as you did the first time,
|
|
the OK button remains inactive. If this happens, try typing the new
|
|
password again.</li>
|
|
</ul>
|
|
|
|
<p>If someone uses your computer who knows or can guess your master password,
|
|
that person may be able to access websites while pretending to be you. This
|
|
can be dangerous—for example, if you manage your financial accounts
|
|
over the Internet.</p>
|
|
|
|
<p>Therefore, it's important to select a master password that's
|
|
difficult to guess. The <strong>password quality meter</strong> gives you a
|
|
rough idea of the quality of your password as you type it based on factors
|
|
such as length and the use of uppercase letters, lowercase letters, numbers,
|
|
and symbols. It does not guarantee, however, that no one will be able to
|
|
guess your password.</p>
|
|
|
|
<p>For further guidelines, see the online document
|
|
<a href="http://home.netscape.com/security/basics/passwords.html"
|
|
target="_blank">Choosing a Good Password</a>.</p>
|
|
|
|
<p>It's also important to record your master password in a safe
|
|
place—and <strong>not</strong> anywhere that's easily accessible
|
|
to someone else. If you forget this password, you may not be able to access
|
|
important information, such as websites that require passwords or
|
|
certificates stored on your computer.</p>

<li>Click Reset Password.</li>
|

</ol>
|
|
|
|
<p><strong>Warning:</strong> If you reset your master password, you will
|
|
permanently erase all encrypted web passwords, email passwords, and form data
|
|
saved on your behalf by Password Manager and Form Manager. You will also lose
|
|
all your personal certificates associated with the
|
|
<a href="glossary.xhtml#software_security_device">software security
|
|
device</a>.</p>
|
|
|
|
<p>Encrypted passwords and form data will be lost only if you have turned on
|
|
encryption for this stored information. For information about turning
|
|
encryption on or off, see
|
|
<a href="using_priv_help.xhtml#turning_encryption_on_and_off">Turning
|
|
Encryption On and Off</a>.</p>
|
|
|
|
<p>If you remember your master password and decide to change it, you can do so
|
|
without danger of losing any personal information. If you are viewing the
|
|
Reset Master Password alert and you decide you want to change your password
|
|
rather than resetting it, click Cancel to return to the Master Passwords
|
|
preferences panel, then click Change Password. For details, see
|
|
<a href="#change_master_password">Change Master Password</a>.</p>
|
|
|
|
<p>Resetting your master password is a last resort that you should use only if
|
|
you are absolutely sure you've forgotten it. The seriousness of the
|
|
situation depends on how much personal data your forgotten master password
|
|
protects.</p>
|
|
|
|
<p>Resetting your master password does not create a new password. Instead, it
|
|
removes all the data your old master password protects. You will be asked to
|
|
specify a new master password the next time the browser needs to store
|
|
personal information.</p>
|
|
|
|
<p>After you reset your master password, you may also want to re-save personal
|
|
information that you want to have prefilled in the future. For example, as
|
|
you browse you may want Password Manager to save website and email passwords
|
|
again.</p>
|
|
|
|
<p>You will also need to enter data by hand until Form Manager accumulates
|
|
enough data to fill in forms automatically. In addition, any personal
|
|
certificates associated with the software security device will be permanently
|
|
erased and you will need to apply for new ones.</p>
|
|
|
|
<p><strong>Note for smart card users:</strong> Each smart card has its own
|
|
master password. The master password for a smart card protects only the data
|
|
on that smart card (such as personal certificates). You can normally change
|
|
the master password for a smart card (assuming that you remember it), but you
|
|
cannot reset it.</p>
