NIST Bans Periodic Password Rotation While Russia's FSTEC Mandates 90-Day Changes for Government Systems

In July 2025, NIST released the final version of SP 800-63B, explicitly prohibiting periodic password changes with the requirement that verifiers and CSPs shall not require subscribers to change passwords periodically. Eight months later, in April 2026, FSTEC approved a methodological document requiring passwords in state information systems and critical information infrastructure to be changed at least every 90 days, with mobile devices limited to 30 days and no reuse of the last 12 passwords. The requirements originate from Order No. 117, which itself contains no mention of passwords, but delegates details to lower-level methodological documents including the April 2026 guide that defines measure IAF.3. Compliance is enforced through the KZI protected indicator calculation submitted to FSTEC twice a year, with penalties including zeroing of the 0.25 weight group for repeated failures and immediate zeroing during penetration testing. The policy applies to government bodies, state unitary enterprises, institutions, and CII subjects, while commercial organizations outside this scope retain flexibility to set their own policies based on threat models. NIST and FSTEC requirements align closely on minimum length, failed attempt limits, MFA for privileged accounts, and prohibition of default passwords, differing primarily on the rotation mandate.
