# User Authentication Overview

Grafana provides many ways to authenticate users. Some authentication integrations also enable syncing user
permissions and org memberships.

## OAuth Integrations

- [Google OAuth]({{< relref "auth/google.md" >}})
- [GitHub OAuth]({{< relref "auth/github.md" >}})
- [Gitlab OAuth]({{< relref "auth/gitlab.md" >}})
- [Generic OAuth]({{< relref "auth/generic-oauth.md" >}}) (Okta2, BitBucket, Azure, OneLogin, Auth0)

## LDAP integrations

- [LDAP Authentication]({{< relref "auth/ldap.md" >}}) (OpenLDAP, ActiveDirectory, etc)

## Auth proxy

- [Auth Proxy]({{< relref "auth/auth-proxy.md" >}}) If you want to handle authentication outside Grafana using a reverse
    proxy.

## Grafana Auth

Grafana of course has a built in user authentication system with password authentication enabled by default. You can
disable authentication by enabling anonymous access. You can also hide login form and only allow login through an auth
provider (listed above). There is also options for allowing self sign up.

### Anonymous authentication

You can make Grafana accessible without any login required by enabling anonymous access in the configuration file.

Example:

```bash
[auth.anonymous]
enabled = true

# Organization name that should be used for unauthenticated users
org_name = Main Org.

# Role for unauthenticated users, other valid values are `Editor` and `Admin`
org_role = Viewer
```

If you change your organization name in the Grafana UI this setting needs to be updated to match the new name.

### Basic authentication

Basic auth is enabled by default and works with the built in Grafana user password authentication system and LDAP
authenticaten integration.

To disable basic auth:

```bash
[auth.basic]
enabled = false
```

### Disable login form

You can hide the Grafana login form using the below configuration settings.

```bash
[auth]
disable_login_form ⁼ true
```

### Hide sign-out menu

Set to the option detailed below to true to hide sign-out menu link. Useful if you use an auth proxy.

```bash
[auth]
disable_signout_menu = true
```
