# Set-PSUAuthenticationMethod

Set-PSUAuthenticationMethod configures authentication settings in PowerShell Universal, including SAML2, OIDC, and other provider types.

## SYNOPSIS

Sets authentication-method settings.

## DESCRIPTION

Configures Forms, SAML2, OIDC, WS-Federation, Domain, and logout authentication settings. For OIDC, use `-ClientCertificate` to supply a client certificate and `-ClientCertificatePassword` when the certificate requires a password. This supports certificate-based client authentication in addition to a client secret.

## EXAMPLE

```powershell
Set-PSUAuthenticationMethod -Type OIDC -CallbackPath '/signin-oidc' -ClientId 'psu' -Authority 'https://identity.example.com' -ClientCertificate 'C:\certs\psu.pfx' -ClientCertificatePassword $env:PSU_OIDC_CERT_PASSWORD
```

## PARAMETERS

* **ClientCertificate**: Client certificate path or value used for OIDC client authentication.
* **ClientCertificatePassword**: Password for the OIDC client certificate.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/powershell-universal/powershell-commands/set-psuauthenticationmethod.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
