Parameters

-AsJob: Runs the cmdlet as a background job. Use this parameter to run commands that take a long time to complete.
-CAServer: Specifies the certification authority (CA) servers that issue certificates for OTP authentication. Specify a server in the following format: -- CAServer_Name\CAService_Name.
-CertificateTemplateName: Specifies the name of the certificate template used for OTP certificate enrollment.
-CimSession: Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
-ComputerName: Specifies the IPv4 or IPv6 address, or host name, of the server on which the cmdlet should run.
-Confirm: Prompts you for confirmation before running the cmdlet.
-Force: Forces the command to run without asking for user confirmation.
-PassThru: Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
-RadiusPort: Specifies the RADIUS server port listening for authentication requests.
-RadiusServer: Specifies the IPv4 or IPv6 address, or the fully qualified domain name (FQDN), of the RADIUS server used for OTP authentication.
-SharedSecret: Specifies the shared password used for communications between the Remote Access server and the RADIUS server.
-SigningCertificateTemplateName: Specifies the name of the certificate template used to enroll the certificate used by Remote Access to sign certificates used for OTP authentication.
-ThrottleLimit: Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0 is entered, then Windows PowerShell® calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
-UserSecurityGroupName: Specifies the security group containing users who are exempt from two-factor authentication.
-WhatIf: Shows what would happen if the cmdlet runs. The cmdlet is not run.

Prerequisites

Windows with the RemoteAccess module and the Windows feature or management tools that provide it. Confirm target connectivity and version compatibility using the linked Microsoft reference.

Security considerations

This cmdlet changes system state. Review every target and parameter in the official reference, test outside production, and prepare an appropriate backup or rollback. Do not execute the example automatically.

Examples

Example 2

Enable-DAOtpAuthentication -CertificateTemplateName DAOTPLogon_v2 -PassThru -Force

This example enables OTP authentication for DA users while keeping the OTP settings for RadiusServer and CAServers that were set before OTP authentication was disabled. The CertificateTemplateName setting was updated to the new value. The new smart card logon short lived certificates template should be created before running this cmdlet.
