IA.L2-3.5.9 · NIST SP 800-171 3.5.9

Temporary Passwords

Allow temporary password use for system logons with an immediate change to a permanent password.

1 point if not metPOA&M eligible1 assessment objective

What gets scored, the objectives

IA.L2-3.5.9 is met only when every one of these 1 objectives, from NIST SP 800-171A, is satisfied. A single missed objective makes the whole requirement not met.

  • a.an immediate change to a permanent password is required when a temporary password is used for system logon

How this is assessed

NIST SP 800-171A defines three assessment methods. For IA.L2-3.5.9, whoever assesses it, including your own team in a self assessment, uses these:

Examine

Identification and authentication policy; password policy; procedures addressing authenticator management; system security plan; system configuration settings and associated documentation; system design documentation; password configurations and associated documentation; other relevant documents or records

Interview

Personnel with authenticator management responsibilities; personnel with information security responsibilities; system or network administrators; system developers

Test

Mechanisms supporting or implementing password-based authenticator management capability

What it means, in context

Changing temporary passwords to permanent passwords immediately after system logon ensures that the necessary strength of the authentication mechanism is implemented at the earliest opportunity, reducing the susceptibility to authenticator compromises.

Users must change their temporary passwords the first time they log in. Temporary passwords often follow a consistent style within an organization and can be more easily guessed than passwords created by the unique user. This approach to temporary passwords should be avoided. Example One of your duties as a systems administrator is to create accounts for new users. You configure all systems with user accounts to require users to change a temporary password upon initial login to a permanent password [a]. When a user logs on for the first tim e, they are prompted to create a unique password that meets all of the defined complexity rules.

What passing evidence looks like

The first logon flow: temporary passwords force an immediate change to a permanent one, shown from the setting or a walkthrough of the new user process.

The step by step walkthrough for Microsoft 365 GCC High, Google Workspace, and on premises setups, plus the exact evidence to capture, lives inside the CMMC Level 2 plan.

Prove IA.L2-3.5.9, and the other 109

The Level 2 workspace walks your team through all 110 requirements at the objective level, drafts your SSP section by section from your own record for your team to read and accept, gives a prime or your own internal auditor a read only seat on the same record, and a credentialed officer reviews every step.

No credit card, and Level 1 and Level 2 are both open, so sign up for the level your contracts call for. Self assessed and self attested: you score yourself in SPRS on a three year cycle and your senior official affirms it every year. As of September 3, 2026 a class deviation directs contracting officers to remove third party assessment from contracts. The program rule still provides for it, so your solicitation sets the track. Your team builds the same evidence either way. DFARS 252.204-7012 is unaffected, and the NIST SP 800-171 Rev 2 baseline is unchanged.

IA.L2-3.5.9 questions, answered
