Users sometimes forget their primary PC login password or trigger an intruder lockout. It is desirable to enable these users to access self-service to resolve their problem, but there is a catch: they cannot sign into their PC so cannot access a conventional web browser or other PC application. How then can they access self-service?

The technical challenge is how to connect users to a self-service mechanism from a pre-login context. The mechanism offered must be evident (or users won't find it), easy to use and secure.

There are three contexts that complicate this problem:

  1. When a user is locked out of the OS login screen; and
  2. When a user is physically off-site; or
  3. When a user is unable to unlock the encrypted filesystem of his PC, at a pre-boot password prompt.

Solution Alternatives

When users forget their primary password or trigger an intruder lockout, they are in a Catch-22 situation: they cannot log into their computer and open a web browser but cannot open a web browser to fix their password and make it possible to log in.

Hitachi ID Password Manager includes a variety of mechanisms to address the problem of users locked out of their PC login screen. Each of these approaches has its own strengths and weaknesses, as described below:

  Option Pros Cons
1

Ask a neighbor: Use someone else's web browser to access self-service password reset.

  • Inexpensive, no client software to deploy.

  • Users may be working alone or at odd hours.
  • No solution for local passwords or mobile users.
  • Wastes time for two users, rather than one.
  • May violate a security policy in some organizations.
2

Hitachi ID Login Assistant: Extends the login screen of Windows systems

  • User friendly, intuitive access to self-service.
  • Can be configured to assist mobile users who forgot their cached domain password (by automatically establishing a temporary VPN connection).
  • Works on Windows Terminal Server and Citrix Presentation Manager.

  • Deployment of client software to every PC.
3

Secure kiosk account (SKA): Sign into any PC with a generic ID such as "help" and no password. This launches a kiosk-mode web browser directed to the password reset web page.

  • Simple, inexpensive deployment, with no client software component.
  • Users can reset both local and network passwords.

  • Introduces a "generic" account on the network, which may violate policy, no matter how well it is locked down.
  • One user can trigger an intruder lockout on the "help" account, denying service to other users who require a password reset.
  • Does not help mobile users.
4

Hitachi ID Mobile Access: Deploy a mobile app, combined with a proxy server in the cloud, to allow users to access the password reset system from their smart phone.

  • Secure and convenient.

  • Does not help with passwords cached on the user's PC, which are not affected when the user's domain password is changed without connection to the PC.
5

Telephone password reset: Users call an automated system, identify themselves using touch-tone input of a numeric identifier, authenticate with touch-tone input of answers to security questions or with voice print biometrics and select a new password.

  • Simple deployment of centralized infrastructure.
  • No client software impact.
  • May leverage an existing IVR system.
  • Helpful for remote users who need assistance connecting to the corporate VPN.

  • New physical infrastructure is usually required.
  • Users generally don't like to "talk to a machine" so adoption rates are lower than with a web portal.
  • Does not help mobile users who forgot their cached domain password.
  • Does not help unlock PINs on smart cards.

Solutions Using Password Manager

Of the above solutions, the first three require no special software. Hitachi ID Systems offers software for each of the remaining alternatives:

Notes and Recommendations
1

Mobile Access

Reset the password using an app on the user's phone.

A proxy server, hosted in the cloud, must broker communication between the user's phone, which is connected to the public Internet and typically has no VPN connection and the on-premise Password Manager server.
2

IVR password reset

Either extend the call flow in an existing IVR system or deploy Hitachi ID Telephone Password Manager, included with Password Manager, to allow users to reset forgotten passwords via phone call. Authentication may be via touch-tone input, speech to text or biometric voiceprint matching.

This mechanism is especially helpful to reset forgotten PINs to OTP tokens, which are often used to sign into the VPN.
3

Domain SKA

Allow users to sign into their network-attached PC with a generic domain account, such as "help" (typically with no password). Launch a kiosk-mode web browser instead of the Windows desktop, to connect users to the password-reset system.

Two drawbacks: the user must be on-premise and a generic account is created on the network. One advantage: easy to deploy.
4

Credential Provider

Adds a new tile to the Windows login screen, used to launch the Login Assistant, which enables access to self-service for locked out users.

Very popular, especially with VPN integration to support off-site users.

Choosing the Right Solution

Ultimately, the choice of technology and business process solutions to the "locked out of login prompt" problem is up to Hitachi ID customers. Password Manager technology supports every technically possible solution.
