Extended CE: Sign Up Page

Sign Up Page

The Sign Up page allows the site administrator to let users register themselves on an Overleaf CE+ server.

The behavior of the registration page is controlled by the following environment variables:

• OVERLEAF_ENABLE_REGISTRATION_PAGE

  • If set to true, the Sign Up page is enabled.
  • If set to false, the Sign Up page is disabled.
  • If not set, the Sign Up page is disabled if any external authentication method is enabled; otherwise, it is enabled.

• OVERLEAF_ALLOWED_REGISTRATION_EMAIL_DOMAINS

  • If defined, restricts user registration to email addresses whose domain matches one of the configured domains.
  • The value is a whitespace- or comma-separated list of domain names.
  • Domain names may include a leading *. wildcard to match subdomains.

Example: To allow registration for users with email addresses such as name@mymail.org, name@company.com, name@math.company.com, and name@sub.example.org, set:

OVERLEAF_ALLOWED_REGISTRATION_EMAIL_DOMAINS=mymail.org, company.com, *.company.com, *.example.org

Note, this configuration does not allow name@example.org.
