# Authentication Options

### 1. Authentication Settings

Authentication options are configured through a mix of UI and Environment variables. To make changes in the UI visit the **Settings > General** tab.

{% hint style="info" %}
Only admins can view and change authentication settings. Some authentication options will not appear in the UI until the corresponding environment variables have been set.
{% endhint %}

### 2. Password Login

By default, the application authenticates users with an email address and password. This is called *Password Login* on the **Settings > General** tab. After you enable an alternative authentication method you can disable password login.

{% hint style="info" %}
The application stores hashes of user passwords that were created through its default password configuration. The first time a user authenticates through SAML or Google Login, a user record is created but no password hash is stored. This is called Just-in-Time (JIT) provisioning. These users can *only* log-in through the third-party authentication service.

If you use Password Login and subsequently enable Google OAuth or SAML 2.0, it’s possible that a user with one email address has two passwords to log-in: their Google or SAML password, and their original password.

We recommend disabling Password Login if all users are expected to authenticate through Google OAuth or SAML as it will reduce confusion.
