Every Decidim is multi-tenant by default. That means that you can have multiple organizations inside of your same installation. This is being used for instance for the Barcelona and Girona Provincials Governments, for offering Decidim installations to many small cities, or by the City of Barcelona, for giving service to lots of organizations (NGOs, cooperatives, etc).

Even if you only have one Organization you also need to create one through the System Panel. It’s available after you’ve installed Decidim, at /system. For instance if you domain is, then it should be available at

After you’ve freshly installed Decidim, you’ll be redirected to the System panel log-in page:

system panel log in

1. Create an admin account

For logging in to this dashboard, you’ll need to create a system admin account from your terminal:

bin/rails decidim_system:create_admin

You’ll be asked for an email and a password. For security, the password will not get displayed back at you and you’ll need to confirm it.

2. Access the Dashboard

With the email and password that you’ve added in the past step, you’ll be able to log in. After you’ve logged in, you’ll see an empty dashboard:

system empty dashboard

3. Create a new organization

Inside of the system panel, you need to create your Organization through the form:

Please mind that some of these fields can’t change through the System Form, as changing them could potentially leave your database in a broken state. You can change it through the console, but you’ll be on your own.
Table 1. System New Organization form
Field Type Description



Name of your organization. For instance, "Decidim Barcelona".

Reference prefix


The reference prefix is used to uniquely identify resources across all organizations. It’s for identifying different resources inside of Decidim. For instance, "BCN". You can change how it’s created this reference through Decidim’s initializer (see Custom resource reference).



Fully qualified domain name. For instance, "" or "".

Secondary hosts


Others domains or subdomains that point to this same installation. Normally this shouldn’t be used. Enter each one of them in a new line. For instance, ""

Organization admin name


Name of the admin account. For instance, "Admin"

Organization admin email


Email for the admin account. For instance, ""

Organization locales


You’ll need to configure at least one language. Decidim is multilanguage, meaning that you can have most of the admin contents with any number of languages. For seeing other languages you’ll need to configure first the Decidim’s initializer.

Force authentication


Check if you want to Force users to authenticate before access organization. That means that they don’t see any published content and they only have access to the log-in form.

Users registration mode


Control how you want the login / participant register or signup to work. See below.

Available authorizations


How you want to authorize and verify that your participants are who they say they are. It depends a lot on your Organization, country, etc. See Authorizations customization.

SMTP settings


Allows you to configure different SMTP servers for every Organzation in this installation. See SMTP configuration.

Omniauth settings


Allows you to configure through external OAUTH providers for every Organization in this installation. See Social providers configuration.

Users registration mode

Allow participants to register and login

Most of the installations use this setting. Means that everyone can register a participant account and login, without restrictions, only with an email account confirmation (and you can disable that confirmation also if you want to through Decidim’s initializer)

Don’t allow participants to register, but allow existing participants to login

This is for when you make a manual import of participants' accounts.

Access only can be done with external accounts

In the case where you have an external provider configured (like the Omniauth settings) and you want to have accounts from only this provider.

[Optional] 4. Edit an organization

Finally, you can also Edit an organization, although some fields can not be changed as some contents in the database depends on them.

For accessing your newly created Organization, you can do it going to the domain or subdomain that you’ve configured in Host.
