## Registration ##
#
# Registration can be rate-limited using the parameters in the "Ratelimiting"
# 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 - d ; now + period],
# where d is equal to 10%% of the validity period.
#
#account_validity:
# enabled: true
# period: 6w
# renew_at: 1w
# renew_email_subject: "Renew your %%(app)s account"
# # Directory in which Synapse will try to find the HTML files to serve to the
# # user when trying to renew an account. Optional, defaults to
# # synapse/res/templates.
# template_dir: "res/templates"
# # HTML to be displayed to the user after they successfully renewed their
# # account. Optional.
# account_renewed_html_path: "account_renewed.html"
# # HTML to be displayed when the user tries to renew an account with an invalid
# # renewal token. Optional.
# invalid_token_html_path: "invalid_token.html"
# Time that a user's session remains valid for, after they log in.
#
# Note that this is not currently compatible with guest logins.
#
# Note also that this is calculated at login time: changes are not applied
# retrospectively to users who have already logged in.
#
# By default, this is infinite.

# Set the number of bcrypt rounds used to generate password hash.
# Larger numbers increase the work factor needed to generate the hash.
# The default number is 12 (which equates to 2^12 rounds).
# N.B. that increasing this will exponentially increase the time required
# to register or login - e.g. 24 => 2^24 rounds which will take >20 mins.
#
#bcrypt_rounds: 12
# Allows users to register as guests without a password/email/etc, and
# participate in rooms hosted on this server which have been made
# accessible to anonymous users.
#
#allow_guest_access: false
# The identity server which we suggest that clients should use when users log
# in on this server.
#
# (By default, no suggestion is made, so it is left up to the client.
# This setting is ignored unless public_baseurl is also set.)
#
#default_identity_server: https://matrix.org
# The list of identity servers trusted to verify third party
# identifiers by this server.
#
# Also defines the ID server which will be called when an account is
# deactivated (one will be picked arbitrarily).
#
# Note: This option is deprecated. Since v0.99.4, Synapse has tracked which identity
# server a 3PID has been bound to. For 3PIDs bound before then, Synapse runs a
# background migration script, informing itself that the identity server all of its
# 3PIDs have been bound to is likely one of the below.
#
# As of Synapse v1.4.0, all other functionality of this option has been deprecated, and
# it is now solely used for the purposes of the background migration script, and can be
# removed once it has run.
#trusted_third_party_id_servers:
# - matrix.org
# - vector.im
# Handle threepid (email/phone etc) registration and password resets through a set of
# *trusted* identity servers. Note that this allows the configured identity server to
# reset passwords for accounts!
#
# Be aware that if `email` is not set, and SMTP options have not been
# configured in the email config block, registration and user password resets via
# email will be globally disabled.
#
# Additionally, if `msisdn` is not set, registration and password resets via msisdn
# will be disabled regardless. This is due to Synapse currently not supporting any
# method of sending SMS messages on its own.
#
# To enable using an identity server for operations regarding a particular third-party
# identifier type, set the value to the URL of that identity server as shown in the
# examples below.
#
# Servers handling the these requests must answer the `/requestToken` endpoints defined
# by the Matrix Identity Service API specification:
# https://matrix.org/docs/spec/identity_service/latest
#
# If a delegate is specified, the config option public_baseurl must also be filled out.
#

#email: https://example.com # Delegate email sending to example.com
#msisdn: http://localhost:8090 # Delegate SMS sending to this local process
# Users who register on this homeserver will automatically be joined
# to these rooms
#
#auto_join_rooms:
# - "#example:example.com"
# Where auto_join_rooms are specified, setting this flag ensures that the
# the rooms exist by creating them when the first user on the
# homeserver registers.
# Setting to false means that if the rooms are not manually created,
# users cannot be auto-joined since they do not exist.
