Summary
For companies of all sizes, the task of supporting users can prove to be taxing on the IT
staff, especially the Help Desk and Administrators. Most studies show the cost of pass-
word resets can range from $25 to $75 per incident and make up around 30 percent or
more of Help Desk calls. This provides ample reason and demand for password reset and
recovery tools which empower the user. By allowing users to self-service their own ac-
count and password management needs, organizations can effectively offer 24/7 access
and maintain productivity.
Shopping for a tool such as this can be challenging, so the first step is to understand your
requirements by documenting your user access scenarios. For example, how will roaming
users change their password remotely or how will a forgotten password be recovered on a
laptop with an encrypted hard drive. Along with these requirements determining your
budget and current Help Desk costs without a solution in place will allow you to forecast
your ROI and further narrow down the vendor selection.
Another point to consider is the evolution of self-service password reset and whether the
vendors you are evaluating are keeping pace. Many tools you’ll find are not compliant with
most companies’ current security standards. The problem of forgotten passwords has
been around since passwords were first used, but expanding access scenarios and ad-
vanced attacks are requiring more advanced solutions. For example, entry point solutions
are now expected to go beyond simple password resets to accept multiple scenarios
which may include disconnected users, auditing and leveraging devices such as mobile
phones.
Of course, true success of a self-service password management solution will be measured
by the users’ satisfaction and an overall reduction in the frequency of their calls to the Help
Desk for support.
The Basics
Self-service password reset is the process a user initiates to prove their identity with the
end goal of resetting their password. Self-service password recovery is similar, but the end
goal is obtaining the current password value without changing it. The user can be authenti-
cated using various methods.
Most tools use challenge question and answer as an acceptable means of authenticating
the user. However, associated security threats including easily guessed answers or infor-
mation readily available on their Facebook page raise valid concerns. A secure solution
puts additional precautions in place. For example, not allowing the same answer for each
question, requiring a minimum answer length, and requiring a larger subset of questions
(e.g. 3 out of 6) to be answered.
For increased security, two-factor authentication can be added to the password reset and/
or recovery to ensure only an authorized user is setting the password.
PortalGuard Centralized Self-service Password Reset
PortalGuard’s self-service password reset is flexible and offers a complete solution which
has evolved with industry demands. By providing the exact same interface for both Win-
dows Desktop and Web-based self-service, the user’s learning curve is minimized and
overall user adoption is increased.

The available self-service actions that PortalGuard offers are password reset, password
recovery, and account unlock. These actions can also be performed from mobile devices
such as iPads and smartphones. PortalGuard integrates seamlessly with Microsoft Active
Directory, Novell eDirectory, any LDAP-compliant directories and custom SQL user reposi-
tories.
PortalGuard also supports users who are offline or disconnected from the network, allow-
ing them to perform a password recovery. In this case, the password is divided into mathe-
matically-represented “shares” with each share being AES-256 encrypted by a separate
challenge answer. All shares are then bulk encrypted with AES-256 using a separate key
and stored locally on the user’s machine. When the user attempts to recover their pass-
word, they will be asked to prove their identity by correctly answering a certain number of
challenge questions. Once decrypted, the user is shown the password in clear text allow-
ing them to continue working. For security purposes, if a disconnected user strikes out
while attempting to authenticate, the encrypted recovery information is deleted from the
local machine, so the user will be forced to reconnect to the network to perform the recov-
ery.
To authenticate the user during an online self-service action, PortalGuard leverages chal-
lenge questions and answers and/or two-factor authentication via a one-time password
sent to a mobile phone or email address. Challenge answers are cryptographically hashed
and stored on a central server to support roaming users and prevent the need to re-enroll
on multiple machines.
By providing auditing and reporting around user access, an Admin App for the mobile
phone, and user verbal authentication through a Help Desk console, PortalGuard is a
comprehensive self-service password reset solution.

How It Works
The following steps show the enrollment and process of resetting a password using Portal-
Guard’s self-service functionality. The screenshots provided are showing the process be-
ing completed from a web browser. A user can also complete the process from the Win-
dows desktop using the same steps and identical interface.
Enrollment
Once self-service password reset is made available, the user will be prompted to enroll
their challenge questions and answers. PortalGuard provides flexibility around this process
by allowing you to configure whether the enrollment will be forced or able to be postponed
“x” number of times by the user. This increases the usability for users, giving them options
around a process some may find obstructive.
NOTE: If other authentication methods are enforced, such as two-factor authentication, then those
enrollment actions will also be displayed, as configured by the admin.

Enrollment Process
NOTE: The screenshots below illustrate the use of PortalGuard’s “sidecar” functionality. It
allows rapid integration of PortalGuard’s self-service features into existing websites or user
processes.
Step 1: The user attempts to login to a company’s existing portal as usual.
Step 2: In this case, the user has not yet enrolled their challenge information so Portal-
Guard automatically displays the enrollment screen in “sidecar” mode. This dialog shows
that the administrator has configured the PortalGuard policy to allow the option of skipping
enrollment temporarily. Doing so will close the PortalGuard dialog and continue the origi-
nal login process. The user can enroll now by clicking “Continue”.

Step 3: The user is prompted to provide answers to the challenge questions. The number
of both mandatory and optional questions the user is required to answer is configurable.
PortalGuard also increases security by helping the user perform best practices when sup-
plying answers, such as not repeating answers or avoiding using words which are included
in the question text.
Throughout the enrollment process the user is provided with helpful warning notices, such
as the number of answers remaining, to ease the frustrations some may feel during this
process.
Step 4: The process is complete and the user is now enrolled. Clicking the link shown will
close the PortalGuard dialog and continue the original login process.

Self-service Password Reset Process
Step 1: The user attempts to login to a company’s existing portal but has forgotten their
password. The user then clicks the “Forgot your password?” link.
Step 2: The user selects from “Recovery Actions Available” which self-service action they
would like to perform. The user selects the “Reset Forgotten Password” radio button and
clicks “Continue”.
NOTE: The dialog shows the most common actions, an account unlock and password re-
set, but password recovery is also available.

Step 3: The user is then prompted to provide their enrolled answers to the enrolled chal-
lenge questions. PortalGuard provides users with helpful warning messages throughout
this process. Once the user has supplied the required number of answers they click
“Continue”.
Step 4: The user’s identity has been verified and they are able to set a new password.
Added usability and security features such as the “Show Password” checkbox and virtual
keyboard can be easily enabled or disabled.
