### Session controls for Combined Registration
By default Combined registration enforces all MFA capable users to strongly authenticate prior to registering or managing their security info. If a user is currently signed in, and previously completed MFA as part of a valid session, no additional MFA is required by default, unless a user is attempting to add or modify a passkey (FIDO2) method. Adding or modifying a passkey (FIDO2) method requires users to have strongly authenticated within the past 5 minutes. If MFA hasn't been completed in the past 5 minutes, the user is asked to sign-in and complete fresh MFA. Organizations can modify the authentication requirements by defining [Conditional Access policies for securing security info registration.](~/identity/conditional-access/policy-all-users-security-info-registration.md).

Use hyphenation for the compound modifier here: "MFA-capable users" (not "MFA capable users").

"sign-in" is used as a verb here. Update to "sign in" (verb) to match Microsoft style and the rest of the article.

- Starting August 25, 2025, as announced in MC1135479, users are required to complete multi-factor authentication (MFA) when managing credentials or accessing My Sign Ins if they haven’t done so within the last 10 minutes of their current session.

This bullet mixes a few inconsistent terms/typography used elsewhere in the doc:

  • Use "multifactor authentication" (no hyphen) for consistency.
  • Use consistent product naming for "My Sign-ins" (the article uses "My Sign-ins" elsewhere).
  • Replace the smart apostrophe in "haven’t" with a straight apostrophe for consistent Markdown text.

Enforcing Authentication Strengths to security info registration can conflict with both aforementioned requirements, with end-users potentially experiencing the error message *"Let’s try something else. Another sign-in method is required to access this resource. Close your browser and try again, but choose another way to sign-in"*. Changes can be made at the tenant level, such as enforcing "Sign-in frequency: every time" to the "Register security info" user action or enabling Passkeys for Windows Hello for Business users, or at the user level, such as ensuring they authenticate with a session at most 10 minutes old or ensuring they authenticate with a combination of methods included in the enforced Authentication Strength.

This paragraph has several consistency/clarity issues:

  • In running text, use lowercase "authentication strengths" unless you’re referring to the UI label.
  • "Enforcing … to security info registration" is ungrammatical; use "for" instead of "to".
  • Consider splitting this into shorter sentences (or a short list) to improve readability, and avoid "end-users" in favor of "users" per Microsoft style.
  • The final "Authentication Strength" reference should be consistent (likely "authentication strength").

You can make changes at either the tenant level or the user level:
- At the tenant level, enforce **Sign-in frequency: Every time** for the **Register security info** user action, or enable passkeys for Windows Hello for Business users.
- At the user level, ensure that users authenticate with a session that's no more than 10 minutes old, or ensure that they authenticate with a combination of methods included in the enforced authentication strength.

Combined registration sessions are only valid for 15 minutes. If a user's registration or management actions take longer than this time period, the session expires and the user is asked to sign back in to continue.
