# Admin guide

You can use Hideez Authenticator as your sole SSO method or explore its full functionality, which includes both passwordless and password-based PC login options. Here are the two possible use scenarios and configuration for them:

1. [**Windows Login:**](/hideez-authenticator-app/admin-guide/setup-for-pc-login-scenario.md)
   * [**Passwordless PC login**](/hideez-authenticator-app/admin-guide/setup-for-pc-login-scenario/passwordless-pc-login-setup.md)
   * [**Password-based PC login**](/hideez-authenticator-app/admin-guide/setup-for-pc-login-scenario/password-based-pc-login-setup.md)

{% hint style="info" %}
**To set up your system environment for passwordless or password-based login, you need to configure SSO on Hideez Enterprise Server.**
{% endhint %}

2. **Single Sign On login to Web Services:**

* [**SSO passwordless login**](/hideez-authenticator-app/user-guide/login-with-hideez-authenticator/sso-login.md#sso-passwordless-login)
* [**SSO login as a second factor**](/hideez-authenticator-app/user-guide/login-with-hideez-authenticator/sso-login.md#sso-login-as-a-second-factor)

{% hint style="info" %}
Additionally, you can use the Hideez Authenticator solely for OTP generation. To do this, configure SSO on HES and then refer to the corresponding guide for [Android](https://authenticator.hideez.com/user-guide/android-guide/otp-generation) or [iOS](https://authenticator.hideez.com/user-guide/ios-guide/otp-generation).
