Self-Service Password Reset (SSPR)

20 mins

Understanding the Concept

Self-Service Password Reset (SSPR) allows users to reset their own passwords without contacting the helpdesk. This reduces IT support costs while improving user productivity. SSPR requires users to register authentication methods that can be used for verification during reset.

SSPR can be configured for cloud-only users or hybrid environments. Password writeback enables cloud-initiated password resets to flow back to on-premises Active Directory, ensuring password synchronization in hybrid identity deployments.

SSPR policies define how many authentication methods are required (one or two), which methods are available (email, phone, authenticator, security questions), and whether users are required to register during their next sign-in.

Key Points

  • SSPR reduces helpdesk password reset calls by 50-70%
  • One or two methods required for verification during reset
  • Combined registration: SSPR and MFA use the same registration flow
  • Password writeback enables cloud resets to sync to on-prem AD
  • SSPR can be scoped to specific groups or enabled for all users

SSPR with Password Writeback

Step 1

User Locked Out

User cannot remember password or account locked

Step 2

Click Reset

User initiates self-service from the sign-in page

Step 3

Verify Identity

User proves identity via registered auth methods

Step 4

Set New Password

User creates new password meeting complexity rules

Step 5

Writeback

New password synced to on-prem AD via Entra Connect

Why This Matters in Real Organizations

Password resets account for 20-50% of helpdesk calls in most organizations. Each call costs $15-25 on average and reduces employee productivity. SSPR directly reduces these costs while empowering users. Combined with MFA registration, it forms a complete self-service authentication management experience.

Common Mistakes to Avoid

Enabling SSPR without password writeback in hybrid environments
Requiring only one auth method for reset (two is more secure)
Not enforcing SSPR registration before it is needed
Using security questions as the only SSPR verification method

Interview Tips

  • Quantify the cost savings from SSPR (helpdesk call reduction)
  • Explain password writeback and its requirements
  • Discuss the combined registration experience for MFA and SSPR

Exam Tips (SC-300)

  • Know the SSPR authentication methods and configuration options
  • Understand password writeback requirements (Entra Connect + P1)
  • Know the difference between one-method and two-method SSPR policies
