Inviting a user to Grafana adds a person to the current organization with a chosen organization role. Use an invitation when the user should accept access with their own account instead of sharing an administrator login or manually creating a password for them.
The invite form is under Administration → Users and access → Users → Organization users. An organization administrator can enter an email address for a new user or a username for an existing Grafana user, then assign Viewer, Editor, Admin, or No basic role.
The Send invite email switch requires working email delivery in Grafana. When email is not configured, leave the switch off and use Pending Invites to copy the invite link for a separate message.

Use the organization switcher first if your account belongs to multiple organizations and the invitation belongs somewhere other than the current organization.

Name is optional. Grafana creates the user account on first sign-in when the invitation uses a new email address.
Viewer can view dashboards and query data sources. Editor can edit dashboards and folders. Admin can manage organization users, teams, data sources, and settings. Use No basic role only when RBAC or another permission model will grant the required access.
Leave it off to create the invite without email and copy the invitation link from Pending Invites.
