# Configure authentication
|
|
|
|
Grafana provides many ways to authenticate users. Some authentication integrations also enable syncing user permissions and org memberships.
|
|
|
|
The following table shows all supported authentication providers and the features available for them. [Team sync]({{< relref "../configure-team-sync" >}}) and [active sync]({{< relref "./enhanced-ldap#active-ldap-synchronization" >}}) are only available in Grafana Enterprise.
|
|

## 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 the login form and only allow login through an auth
|
|
provider (listed above). There are also options for allowing self sign up.
|
|
|
|
### Login and short-lived tokens
|
|
|
|
> The following applies when using Grafana's built in user authentication, LDAP (without Auth proxy) or OAuth integration.
|
|
|
|
Grafana uses short-lived tokens as a mechanism for verifying authenticated users.
|
|
These short-lived tokens are rotated on an interval specified by `token_rotation_interval_minutes` for active authenticated users.
|
|
|
|
Inactive authenticated users will remain logged in for a duration specified by `login_maximum_inactive_lifetime_duration`.
|
|
This means that a user can close a Grafana window and return before `now + login_maximum_inactive_lifetime_duration` to continue their session.
|
|
This is true as long as the time since last user login is less than `login_maximum_lifetime_duration`.
|
|
|
|
#### Remote logout
|
|
|
|
You can logout from other devices by removing login sessions from the bottom of your profile page. If you are
|
|
a Grafana admin user, you can also do the same for any user from the Server Admin / Edit User view.
|
|
|
|
## Settings
|
|
|
|
Example:
|
|
|
|
```bash
|
|
[auth]
|
|
|
|
# Login cookie name
|
|
login_cookie_name = grafana_session
|
|
|
|
# The maximum lifetime (duration) an authenticated user can be inactive before being required to login at next visit. Default is 7 days (7d). This setting should be expressed as a duration, e.g. 5m (minutes), 6h (hours), 10d (days), 2w (weeks), 1M (month). The lifetime resets at each successful token rotation (token_rotation_interval_minutes).
|
|
login_maximum_inactive_lifetime_duration =
|
|
|
|
# The maximum lifetime (duration) an authenticated user can be logged in since login time before being required to login. Default is 30 days (30d). This setting should be expressed as a duration, e.g. 5m (minutes), 6h (hours), 10d (days), 2w (weeks), 1M (month).
|
|
login_maximum_lifetime_duration =
|
|
|
|
# How often should auth tokens be rotated for authenticated users when being active. The default is every 10 minutes.
|
|
token_rotation_interval_minutes = 10
|
|
|
|
# The maximum lifetime (seconds) an API key can be used. If it is set all the API keys should have limited lifetime that is lower than this value.
|
|
api_key_max_seconds_to_live = -1
|
|
|
|
# Enforce user lookup based on email instead of the unique ID provided by the IdP.
|
|
oauth_allow_insecure_email_lookup = false
|
|
```
|
|
|
|
### 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
|
|
authentication integration.
|
|
|
|
To disable basic auth:
|
|
|
|
```bash
|
|
[auth.basic]
|
|
enabled = false
|
|
```
|
|
|
|
### Disable login form
|
|
|
|
Hide the Grafana login form using the below configuration settings.
|
|
|
|
```bash
|
|
[auth]
|
|
disable_login_form = true
|
|
```
|
|
|
|
### Enable email lookup
|
|
|
|
Enable user lookup based on email in addition to using unique ID provided by IdPs.
|
|
|
|
By default, Grafana relies on the user unique ID provided by the identity provider.
|
|
Looking up users by email can be safe for some identity providers (for example, when they are single tenants and unique non-editable, validated emails are provided), as well as in some infrastructures.
|
|
|
|
We strongly recommend against enabling email lookups, however it is possible to do with the following configuration.
|
|
|
|
```bash
|
|
[auth]
|
|
oauth_allow_insecure_email_lookup = true
|
|
```
|
|
|
|
### Automatic OAuth login
|
|
|
|
Set to true to attempt login with specific OAuth provider automatically, skipping the login screen.
|
|
This setting is ignored if multiple auth providers are configured to use auto login.
|
|
Defaults to `false`.
|
|
|
|
```bash
|
|
[auth.generic_oauth]
|
|
auto_login = true
|
|
```
|
|
|
|
### Avoid automatic OAuth login
|
|
|
|
To sign in with a username and password and avoid automatic OAuth login, add the `disableAutoLogin` parameter to your login URL.
|
|
For example: `grafana.example.com/login?disableAutoLogin` or `grafana.example.com/login?disableAutoLogin=true`
|
|
|
|
### Hide sign-out menu
|
|
|
|
Set the option detailed below to true to hide sign-out menu link. Useful if you use an auth proxy or JWT authentication.
|
|
|
|
```bash
|
|
[auth]
|
|
disable_signout_menu = true
|
|
```
|
|
|
|
### URL redirect after signing out
|
|
|
|
URL to redirect the user to after signing out from Grafana. This can for example be used to enable signout from OAuth provider.
|
|
|
|
```bash
|
|
[auth]
|
|
signout_redirect_url =
|
|
```
|
|
|
|
### Protected roles
|
|
|
|
{{% admonition type="note" %}}
|
|
Available in [Grafana Enterprise]({{< relref "../../../introduction/grafana-enterprise" >}}) and [Grafana Cloud]({{< relref "../../../introduction/grafana-cloud" >}}).
|
|
{{% /admonition %}}
|
|
|
|
By default, after you configure an authorization provider, Grafana will adopt existing users into the new authentication scheme. For example, if you have created a user with basic authentication having the login `jsmith@example.com`, then set up SAML authentication where `jsmith@example.com` is an account, the user's authentication type will be changed to SAML if they perform a SAML sign-in.
|
|
|
|
You can disable this user adoption for certain roles using the `protected_roles` property:
|
|
|
|
```bash
|
|
[auth.security]
|
|
protected_roles = server_admins org_admins
|
|
```
|
|
|
|
The value of `protected_roles` should be a list of roles to protect, separated by spaces. Valid roles are `viewers`, `editors`, `org_admins`, `server_admins`, and `all` (a superset of the other roles).
