I just migrated off of Authy last week but I was probably caught in this breach, ugh. Never liked it but they make it extremely difficult to export your data. I used this project for exporting: https://github.com/alexzorin/authy EDIT: it appears this project was actually using the unauthenticated endpoint (used in breach, too) to facilitate exporting, lol. Good luck to anyone trying to get off of Authy, Twilio really…

What did you end up moving to?

I have removed all SMS based 2FA from every account that allows it and you should too.

I'm a bit confused how this is relevant. Authy is a OTP app, nothing to do with SMS.

Authy uses SMS based recovery of your entire account, a weaker link that a single service using SMS based OTP

Earlier quoted context omitted.

I also just recently left for Aegis and have been very happy. I feel much better knowing that my 2FA is completely offline

Right, I did the same a while back. Aegis for Android and 2FAS for iOS. Never looked back. Also, if anyone is going either direction, Android iOS, both of these open source options allow easy export.

2FAS also exists for Android, is Aegis superior or you don't use 2FAS on Android for another reason?

> Twilio has detected that threat actors were able to identify data associated with Authy accounts, including phone numbers, due to an unauthenticated endpoint. We have taken action to secure this endpoint and no longer allow unauthenticated requests How do I avoid such problems in my own app? Force authentication for all requests with row-level security? Rate limiting? Any testing frameworks that would catch this? S…

This is actually a use-case I use for interviews.

1. Everyone tests authenticated user can do the right thing.

2. Can authenticated user access the data?

3. Can an unauthenticated user access data?

If there’s a testing framework that does this scaffolding automatically, I’d love to hear it.

Has anyone found a single open-source app that supports both mobile and desktop though? That was the attraction of Authy before they killed their desktop apps.

Does anyone have a recommendation for an Open Source 2FA OTP app? That's the only thing I use Authy for, to scan the QR Codes into the App and generate the 2FA tokens, but in a way that allows me to migrate to another phone without having to re-set all the 2FA tokens on the vendor side.

For Android, if you happen to use Keepass as your password manager, I really like KeePassDX[0]. If the camera app you use doesn't support QR scanning, though, you'd need an app for that (and I don't think any FOSS camera apps implement this, as for as I can tell). This one[1] seems the most up-to-date, by a German research group. You'd share the link as text to the KeePassDX app, search for the entry it's for, and it…

I started with Keepassium but ended up with Strongbox which has been great.

I think that is intentional, AFAIK phone communication is more protected than other types so allowing spam to continue unabated is in the governments interest. Outsourcing the harassment to 3rd parties, similar to how prison torture is outsourced to the inmates. The government could fix these things but would rather not.

I think we just don't have very much competition in telecommunications so things never get fixed. Why bother? It's easier to extract rent off largely the same offerings as the rest of your market (difficult to understand pricing tiers that function as a congestion tax more than a transaction, often region-specific monopolies or duopolies, indistinguishable quality of service) and bring home large profits, market effi…

Almost no-one is pro-spam, it’s pretty much universally hated, and in many cases it’s already illegal so it’s more of a matter of enforcement. It is also trivial to detect.

Sure there probably is some regulatory capture but if anything at all can be regulated it’s spam calls / messages. If the government can’t regulate spam then what could it be expected to regulate.

The general population is increasing worried about scam calls for their elderly relatives, it’s already a big deal.

I use Authy’s iOS app to generate 2FA tokens for a few accounts. I cannot remember ever entering my phone number into it, or establishing an Authy account of any kind. Is there some other way they would have acquired my phone number? I’m trying see if the issue is some unanticipated issue with the iOS client app itself, or if it is only affecting people who created online accounts with Authy to sync their 2FA credent…

Entering your phone number was mandatory. This was what turned me away [1] from Authy to Duo Mobile on my Apple devices.
