# section of this file.
# Enable registration for new users.
#
#enable_registration: false
# Optional account validity configuration. This allows for accounts to be denied
# any request after a given period.
#
# ``enabled`` defines whether the account validity feature is enabled. Defaults
# to False.
#
# ``period`` allows setting the period after which an account is valid
# after its registration. When renewing the account, its validity period
# will be extended by this amount of time. This parameter is required when using
# the account validity feature.
#
# ``renew_at`` is the amount of time before an account's expiry date at which
# Synapse will send an email to the account's email address with a renewal link.
# This needs the ``email`` and ``public_baseurl`` configuration sections to be
# filled.
#
# ``renew_email_subject`` is the subject of the email sent out with the renewal
# link. ``%%(app)s`` can be used as a placeholder for the ``app_name`` parameter
# from the ``email`` section.
#
# Once this feature is enabled, Synapse will look for registered users without an
# expiration date at startup and will add one to every account it found using the
# current settings at that time.
# This means that, if a validity period is set, and Synapse is restarted (it will
# then derive an expiration date from the current validity period), and some time
# after that the validity period changes and Synapse is restarted, the users'
# expiration dates won't be updated unless their account is manually renewed. This
# date will be randomly selected within a range [now + period ; now + period + d],
# where d is equal to 10%% of the validity period.
