Authenticator Login Plus (2FA)

Critical · no install count published · SA-CONTRIB-2026-197 · on drupal.org · Week of 7 October 2026

It provides two factor verification for the login process.

A person with a valid password reset link could access an account without passing the second security step. They could skip the extra security check entirely. This could allow them to see and change restricted data.

  • Who could do thisAnyone visiting the site. No login needed.
  • Does it apply to youA site is affected if an attacker has access to a valid one time login link for a victim.
  • Has it been used in attacksNo sign of it.
  • How urgentDrupal rates this critical. Cyber Essentials expects a fix within 14 days. Do it this week.

For developers: what the fix changed

The fix updates src/Form/LoginChallengeForm.php and src/Controller/ResetRequestController.php to properly enforce two factor authentication for users logging in via a one time login link. It ensures these users are correctly redirected to the password reset page after verification.

Tell your developerUpdate Authenticator Login Plus (2FA) to 1.0.1.

For developers: what the fix changed

The fix modifies the login enforcement subscriber to check if two factor authentication is enabled rather than merely existing. It also updates the user enrol form to force re enrolment if a user has disabled their two factor authentication.

Also in this release REST login endpoints and reset request controllers were updated to handle edge cases and block invalid sessions.

Not sure what your site is running?

Send me your Drupal site's address.

I'll tell you what I can see from outside, what the Drupal 10 end of life on 9 December means for it, and what it would cost to have me keep it patched. There's no charge for that and no obligation. peter@peterbrady.co.uk

Get in touch

Tell me who you are, what your organisation does, and what you need. That might be a Drupal site that needs looking after, an upgrade to get done before December, or an agency that needs Drupal cover.

If I can help, I'll say so and suggest a call. If I can't, I'll tell you straight away rather than waste your time.

For context: I work mainly with UK charities, membership bodies and research organisations, and with the agencies that look after their websites. Not recruiters.

Or start smaller and connect with me on LinkedIn. That's where I post what I find digging around in charity and grants data, and where the free tools turn up first.
