What Hacker News says
11 sourcesHey again, so I got curious about this "Alexa ranking" requirement - and it's fucking crazy bananas at this point.
The current maintainers are actively removing data that doesn't meet the "Alexa 200K" "requirement", and other PRs have been closed as "not in Alexa 100K".
https://github.com/2factorauth/twofactorauth/search?q=alexa&...
If this were a project I'd started and saw the new maintainers doing what they are, I'd be livid.
I cannot fathom the scenario where it makes sense to remove correct, useful information like this.
In 2FA Notifier – Know when a site supports 2FAHey, the two PR's are here: https://github.com/2factorauth/twofactorauth/pulls?utf8=&q=i...
As mentioned, one has been merged, but with incorrect information. The company in question (VentraIP) has actually got a better document about this now (https://ventraip.com.au/faq/article/two-factor-authenticatio...), but I'm honestly beyond done with the current maintainers of that repo so I'm not willing to add further info to the PRs.
In 2FA Notifier – Know when a site supports 2FAI am not a core committer for twofactorauth.org (yet! I hope to become one!), so I cannot say whether they will accept a PR like that. However, there is an open issue discussing this topic that is worth reading over [1].
2FA Notifier has a bit of an easier job since we don't have to render anything or make it searchable (as of today). I would happily review any PRs along these lines! The data is currently hard coded in a Typescript file, which makes it really easy to update [2].
I plan to document criteria for contributing data to 2FA Notifier like this, but just haven't had the time. One entry per PR would be ideal if you are motivated to contribute!

In 2FA Notifier – Know when a site supports 2FAThat is a great idea! I am 100% in favor of helping the users understand the security tradeoffs between the 2FA methods.
We definitely have it on the roadmap to update 2FA Notifier to include more educational content. Thanks for the feedback!
I am currently writing a series on 2FA on my site All Things Auth [1] that gets into the details explaining how each method works and exploring the security and usability tradeoffs of each. I want to put together a summary and/or infographic highlighting the main takeaways and hopefully like to something like that from 2FA Notifier.
Currently, we use the data from twofactorauth.org [2] as our main data feed. I definitely encourage you to check out their community on GitHub and propose your idea there too!

In 2FA Notifier – Know when a site supports 2FAThe problem seems to be that no German bank I know of support 2FA for login purposes which is what that list tracks[0] (although they don't state that clearly – it took me a few minutes to track that down)
But listing "Sparkasse" as one German bank is misleading as there are 400 independent banks sharing that brand with different policies. They use at least a few different backends for their online system although there seemed to have been some consolidation in recent years.

In Two Factor Auth List of WebsitesHmmm, what are you seeing that's not clickable? I don't use vimium and I can click on the site name, docs links, and tell-them-to-two-factor-via-twitter.
Whoop. Looks like the tiling system is relying on JavaScript instead of <a> tags for links:
```
<div id="communication" class="category column" style="display: block;">
<h5 class="ui icon header">
<i class="circular chat icon"></i>
<small>Communication</small>
</h5>
</div>
```
The contributors are pretty responsive, so I'd recommend noting the issue: https://github.com/2factorauth/twofactorauth/issues
