Notifier

Authelia sometimes needs to send messages to users in order to verify their identity.

Startup Check

The notifier has a startup check which validates the specified provider configuration is correct and will be able to send emails. This can be disabled with the disable_startup_check option:

# Configuration of the notification system.
#
# Notifications are sent to users when they require a password reset, a u2f
# registration or a TOTP registration.
# Use only an available configuration: filesystem, smtp.
notifier:
  # You can disable the notifier startup check by setting this to true
  disable_startup_check: false
