Email (OTP) authentication
Firezone supports email authentication using a one-time password (OTP).
This connector is enabled by default for all plans and is designed to get you up and running with Firezone quickly. For production deployments, we recommend setting up Universal OIDC, Google Workspace, Microsoft Entra ID, or Okta authentication.
Firezone's OTP-based email authentication connector sends a one-time password to the user's email each time authentication is requested. This password is short-lived and can only be used to authenticate once.
User / group sync is not supported with the Email (OTP) connector. See the Google Workspace, Microsoft Entra ID, or Okta connectors for automatic directory sync.
Disabling email authentication
The email authentication connector can be disabled completely for your account, forcing all users and admins to authenticate with another connector. However, this can lead to issues signing in if one of your other authentication connectors stops working. For that reason, you may want to leave the email authentication connector enabled with at least one admin for recovery purposes.
