[nodebb-plugin-2factor] Two-Factor Authentication

julian

In addition to regular authentication via username/password or SSO, a second layer of security can be configured, permitting access only if a time-based one-time password is supplied, typically generated/stored on a mobile device.

The Two-Factor Authentication plugin will expose this feature to end-users, allowing them to configure their
devices and enabling this enhanced security on their account.

Requirements

Requires NodeBB v0.7.2 or newer.

Installation

Install the plugin via the ACP/Plugins page.

Very nice! Works fine.

julian

Good to hear it @revunix

I hope to add support for reset keys and ACP deactivation, as currently, if you lose your device, you won't be able to bypass

drew

@julian I recently had my phone smashed by a drunk friend (I could just make out the numbers on a flickering screen) and discovered how terrible the "reset code" or "add code to another device" situation is with a new phone on sooo many websites where I had 2FA, even if you can get in with your current one.

Robert

@drew Indeed, I don't know how many support tickets I will need to make for all the sites where I use 2 factor auth, 3 Google accounts, Steam, Cloudflare and much more...

Anyways 2FA looks nice.

julian

Published an update. (Changelog in OP)

@drew @kowlin At least now the administrator can reset TFA keys, although getting in touch with the admin is another matter altogether

Nicholas "LB" Braden

Are backup codes supported now btw? I see a closed GitHub issue for them, which suggests they are.

julian

@LB Yep, they are, although they are generated only when you start the 2FA setup process, so you will want to disable 2FA, trash your record, and re-generate one. The backup codes will be displayed a single time for you to record.

When I scan this with Authy or Google Authenticator it says "QR code is invalid" no matter how many times I create a new one. Is there a fix?

Alex Bro

@cookieman768 The same situation(((

Plug-ins no longer work with the version «1.7.5».

julian

@ilya Can you elaborate on what doesn't work? Saying "no longer work" doesn't help narrow down any problems.

Yosimoto

@julian The problem was solved with FreeOTP Authenticator (Android).

@ilya This plugin no longer works with 1.17. Error below

I've just seen an update for this plugin. Is it compatible now ?

julian

v5.0.0 of the 2factor authentication plugin has been published. It now allows for concurrent second factors, so you can have both a hardware key and an authenticator app in use at the same time.

When challenged, you can use either option to verify your identity.

julian

v7.4.0 of this plugin now notifies you in the event that your account was accessed, but the second factor challenge was not passed.

This provides a much-needed notification for the user that their password has been compromised and is in need of changing.

NodeBB (@[email protected])

Attached: 1 image The Two-Factor Authentication plugin that comes bundled with #NodeBB was just updated to v7.4.0. It now notifies you if your account was accessed, but the second factor challenge was not passed. If you see this notification, and it wasn't you, you just might want to change your now-compromised password! Oft forgotten, this feature provides much needed positive reinforcement that, yeah, #2FA works! #appsec #security #2factor

@julian this is amazing feature!!! Thank you!

RazielKanos

when i try to add a hardware key i instantly get the message "hardware key registration abborted" and in the logs i found this:
2023-11-20T06:03:39.301Z [4567/995] - info: [plugin/2factor] Denying socket access for uid 2 pending second factor.

Any idea how I can fix this?

julian

Hmm, that actually sounds like a bug. Can you let me know your NodeBB version and 2factor plugin version?

I'll try to take a look tomorrow
