= '/Pages/Shared/_Layout.cshtml' ДЄlso assign the layout for all the manage pages from the Identity pages: = '_Layout.cshtml' Define the layout in the Identity/Account/Manage/_Layout.cshtml file. Scaffold the Identity pages into the app. Var identity = (ClaimsIdentity)principal.Identity Д«ecause the Identity service setup changed in the Startup class, the layouts of the Identity need to be updated. Var principal = await base.CreateAsync(user) Public async override Task CreateAsync(IdentityUser user) : base(userManager, roleManager, optionsAccessor) Public AdditionalUserClaimsPrincipalFactory( Public class AdditionalUserClaimsPrincipalFactory : If the database view is read from the database directly instead of using the claim, it's possible to access the view without MFA directly after activating the MFA. The claim is added here because the user should only access the higher protected view if the identity has logged in with MFA. The claim's value is read from the database. The AdditionalUserClaimsPrincipalFactory class adds the amr claim to the user claims only after a successful login. public void ConfigureServices(IServiceCollection services)Д¬onfiguration.GetConnectionString('DefaultConnection')))

The AddIdentity method is used instead of AddDefaultIdentity one, so an IUserClaimsPrincipalFactory implementation can be used to add claims to the identity after a successful login.

The demo code is setup using ASP.NET Core with Identity and Razor Pages.

For example, users might be able to view the profile data using a password login, but an administrator would be required to use MFA to access the administrative pages. This could be useful for apps where different levels of access exist for the different identities.

MFA could be forced on users to access sensitive pages within an ASP.NET Core Identity app. NIST guidelines Configure MFA for administration pages using ASP.NET Core Identity Too many known attack vectors exist for this type of implementation. However, using SMS as a second factor is no longer recommended. MFA with SMS increases security massively compared with password authentication (single factor). For more information, see Passwordless authentication options for Azure Active Directory. FIDO2 can be used for MFA or passwordless flows.ДЄzure Active Directory provides support for FIDO2 and passwordless flows.

The only MFA flow that protects against phishing attacks.ДЄt present, ASP.NET Core doesn't support FIDO2 directly.

See the following link for implementation details:Д®nable QR Code generation for TOTP authenticator apps in ASP.NET Core MFA FIDO2 or passwordless This can be used together with any compliant authenticator app, including: MFA using TOTP is a supported implementation using ASP.NET Core Identity. MFA TOTP (Time-based One-time Password Algorithm) Two-factor authentication (2FA) is like a subset of MFA, but the difference being that MFA can require two or more factors to prove the identity. MFA requires at least two or more types of proof for an identity like something you know, something you possess, or biometric validation for the user to authenticate.

Force ASP.NET Core OpenID Connect client to require MFA.

Send MFA sign-in requirement to OpenID Connect server.

Configure MFA for administration pages using ASP.NET Core Identity.What is MFA and what MFA flows are recommended.The additional factor isn't easily obtained or duplicated by an attacker. When you require a second form of authentication, security is enhanced. This prompt could be to enter a code from a cellphone, use a FIDO2 key, or to provide a fingerprint scan. Multi-factor authentication (MFA) is a process in which a user is requested during a sign-in event for additional forms of identification.
