Access Policy

Authara supports an optional email allowlist to restrict which users may access the system.

When enabled, only explicitly allowed email addresses are permitted to:

  • register new accounts
  • authenticate via any provider (password or OAuth)
  • create and refresh sessions

This feature is designed for controlled environments such as internal tools, early-access products, or staged rollouts.

Overview

The access policy operates as a central enforcement layer across Authara:

  • evaluated during signup
  • evaluated during login
  • enforced during session creation
  • enforced during session refresh

This ensures that access restrictions remain consistent even after a user has already authenticated.

Enabling the allowlist

Enable the feature via configuration:

AUTHARA_ACCESS_POLICY_ALLOWLIST_ENABLED=true

When disabled, all emails are allowed and no additional access-policy checks are performed. The admin allowlist UI is hidden, admin allowlist routes return 404 Not Found, and allowlist service methods reject use.

When enabled, admins can manage allowlisted emails under /auth/admin/allowlist. The management page supports paginated live search. Add and remove operations are state-changing POST actions and require CSRF protection.

Behavior

Allowed email

If an email is present in the allowlist:

  • signup proceeds normally
  • login succeeds if credentials are valid
  • sessions can be created and refreshed

Disallowed email

If an email is not present in the allowlist:

  • signup is rejected
  • login is rejected
  • session refresh is rejected

Use cases

  • Internal applications with restricted access
  • Private beta or invite-only products
  • Gradual rollout of new systems
  • Security-sensitive environments requiring strict admission control
