If you're moving a site to Craft from a legacy system like ExpressionEngine, Wordpress, or BigCommerce, you can use Legacy Login to authenticate and migrate your legacy users — seamlessly, without inconveniencing your users unnecessarily.


Legacy Login plugin provides a way to authenticate users from a legacy system into your Craft CMS site.

The legacy-login/login custom action stands in for Craft's native login form action. If a submitted loginName/password fails Craft's native authentication, the plugin checks the legacy system(s) and tries to authenticate a user from there. If a matching legacy user is found and authenticated, the plugin creates or updates the User in Craft and logs into the newly created/matched account.

What legacy systems are supported?

Legacy Login provides drivers for authenticating legacy users from:

  • Craft CMS 4.x
  • Craft CMS 3.x
  • Craft CMS 2.x
  • ExpressionEngine 2.x
  • WordPress

Two legacy drivers are not yet ported to the Craft 4 version of Legacy Login:

  • BigCommerce (Self-hosted)
  • Wellspring

Price includes 1 year of updates.
$9/year per site for updates after that.
