For some reason I have it in the back of my mind that they were at one point accused of being a honeypot for US intelligence because of their association with MIT. Probably complete BS, but maybe not. Are they as open source as they claim to be? Looks like they're on github. F-Droid seems to think they have some Google libraries or whatever that they use.

ProtonMail users, how do you like/dislike it?

I’m on the edge of quitting protonmail. The issues:

  • #CAPTCHA hell. At least for Tor users.
  • no app in f-droid
  • API shenanigans and/or CAPTCHA breaks hydroxide (the foss bridge)
  • protonvpn: you can no longer fetch all the configs in one download. You have to click “download” >120 times now to get all the configs
  • account locks if you do not login frequently enough (i think every 6 months)
  • if you supply your login creds but get a CAPTCHA and say fuck this, and walk, it does not count as a full login needed to reset the expiration clock
  • the CAPTCHAs are graphical which forces you to enable images in your browser; but when you do that you get images that junk up your screen and waste bandwidth
  • no public keyring. Hushmail was better in this regard. An advanced user could upload their PGP public key to Hushtools and then encryption just worked for hushmail users contacting that person. After Hushmail started charging, I would tell the normies who need comms w/me to get a gratis Protonmail account. But then I have to send them my public key and they have to figure out how to attach it to my profile in their phonebook. It’s a show-stopper in many situations.

For what it's worth, I think if you add the izzysoft repo to F-Droid (https://apt.izzysoft.de/fdroid/repo) then you'll get the ProtonMail App; I think regular F-Droid has only the VPN.

[–] [email protected] 2 points 5 months ago

Protonmail failed to satisfy F-Droid’s inclusion criteria because it requires gms (playstore framework) and because it uses Firebase messaging.

Since I’ve disabled gms in my device I’m not sure how Protonmail would work for me. Someone tells me I might simply lose push notifications capability. But I am confused because Snikket pushes notifications just fine on my device.

Proton AG lost me as a customer the minute they backdoored a binding arbitration clause into their TOS last year.

The difficulty of proving damages in breach of privacy cases combined with generally weak privacy legislation globally means the threat of a class action often serves as one of the only practical deterrents to abuses of power by corporations controlling sensitive personal information. By changing its terms of service, Proton essentially immunized itself from suffering any significant penalty in the event its negligence leads to a mass breach of privacy of its users.

Tactics like the use of binding arbitration clauses are hallmarks of inherently untrustworthy corporations.

My only major complaint is their free-tier is a bit lacking compared to what Skiff had (or I guess has, but not for much longer.) I think their platform is great, and definitely worth paying for, but given I'm a broke college student that's not much of an option. Also their support for third party clients (or lack thereof) isn't great, though I don't use those as much. Otherwise I like it quite a bit!

[–] [email protected] 6 points 6 months ago (1 children)

Only thing would be the closed source server and no third party apps. They do have an API, but I haven't found anything written on top of that.

I'm not entirely sure why expected a user-owned private key 🤔 How do they ensure zero knowledge if you send them the username and password?

Not 3rd party of course but most of their official clients are FOSS.

Because you don't. I haven't looked into how it works exactly but all your browsers sends is your username and a proof of you having access to the password

General rule of thumb:

  1. Web: can change at any moment, can serve a highly secure mail web app... except to those it might decide to target, giving them zero notice, leaving close to zero trace.
  2. Electron based "app": if it can run random JS from the web, see first point.
  3. Compiled app: to change its way of working, the user needs to update/download a different version. An explicit user action is required, people can notice malicious changes and warn others about them.
  4. Compiled open source app: same as a compiled app, except people can also notice malicious changes before running the code, fork it to remove them, compile it themselves, and warn others.

ProtoMail, touts itself as a "secure web app", which is a contradiction.

If you use an open source app to access ProtonMail's service, the security lies in whatever app you use. At that point, might as well send E2E encrypted mail via GMail.

TL;DR: the way most people use it, is just security theatre.

From a security stand-point: Yes. From a privacy standpoint: Absolutely not.

[–] [email protected] 2 points 6 months ago* (last edited 6 months ago) (1 children)

Both privacy and security are the same in either case:

  • Both servers know who's connecting
  • Both servers see the connecting IP
  • Both servers know the source and target mail addresses
  • Neither server knows the message's content
  • Neither server controls the client's app

The moment you go off-VPN, or use a webapp, security goes out the window.

Privacy, as in social network/contacts, goes out the window the moment you use a fixed email address; more so if it's associated to your IRL identity.

There's a large difference between surrendering massive amounts of highly critical metadata aswell as some data* to a known abuser vs. an entity that prides itself in not abusing your data and which even takes specific technological measures to make it as hard for them as possible (zero access encryption at rest, automatic key discovery).

(* Partial social graph, interaction timestamps, political interests, health, hobby interests and much of that usually even in plain text data form when receiving email; stored in in plain text forever.)

Right, "don't be evil" 🙄. Corporations are corporations.

Also called "encryption". Just so we're on the same page:

  • 1991: initial release of PGP
  • 2016: initial proposal and implementation of WKD

Enigmail for Thunderbird supports both since 2018. The mail service, be it ProtonMail, GMail, Outlook, etc., is irrelevant regarding security or privacy.

[–] [email protected] 2 points 5 months ago (1 children)

FYI Thunderbird now natively supports PGP (and possibly WKD?) without the need for Enigmail.

Proton fell into the black hole when they pitched to replace Gmail on Huawei phones. Being eager to do business with the CCP was a dealbreaker.

That said, I have a Tuta account. I don't use it for everything, but I have no complaints.

[–] [email protected] 12 points 6 months ago

I've had good luck. Reliable and fast as any other service.

I'm a 3rd year subscriber of the Unlimited plan, $158 for 2 years at a time. I utilize the drive, aliases, mail and VPN.

No real complaints. I still use Google calendar because it integrated more with Android phone. I still consider going back to Gmail occasionally for simplicity. I really hate Gmail though but email is garbage. Does it really matter?

I basically priced out good vpn's, and the two year price of proton was pretty similar to most other quality VPN plans. So why not stick with it and get the rest of the ecosystem too.

I don't think about it too much, it's email and it works.

I do not care about secure email because I don't communicate with anyone else using it, but I do like how it automatically blocks trackers and cleans email links for me.

My experience has been fine. If you go into Proton Mail with the understanding that you're doing it to stop Google from data mining your email, and not for the sake of truly private/anonymous email, you'll have a good time. The aliasing feature is super nice as well.

[–] [email protected] 2 points 6 months ago (1 children)

I can't get contact photos to display on PM. Tuta doesn't have this feature at all, but the fact that PM appears to, but doesn't work; well, it shouldn't, but little things like that drive me crazy.

[–] [email protected] 2 points 6 months ago

Funnily enough, I don't know that I've ever even paid attention to contact photos (not that 99% of the people I email have would have them anyways.)

If you go into Proton Mail with the understanding that you’re doing it to stop Google from data mining your email

You're not really stopping anything if most of the people you're emailing are still using Google or Microsoft :) Because they'll get a copy of your email then anyway. This is really the problem with email IMO. Well, one of the problems, a lack of sender authentication is another one.

[–] [email protected] 4 points 6 months ago

I'm mostly just protecting the mountain of old stuff in my archives that I'm too much of a digital hoarder to delete. ;D

a lack of sender authentication is another one

This one is a nightmare. We spend bucketloads on DMARC shit in our department, only to still have loads of issues with email spoofing.

[–] [email protected] 9 points 6 months ago (1 children)

What qualifies as being truly private/anonymous email in your book? Or does such a thing even exist?

[–] [email protected] 18 points 6 months ago (1 children)

Based on the reading I've done, it doesn't really seem like one exists - it's just not what email was designed to do. I'm not an infosec professional, but that's the impression I've been given by others in the field.

[–] [email protected] 2 points 6 months ago

it's just not what email was designed to do.

Email was designed decades ago, before the concept of data-mining even existed. It probably didn't occur to the creators how universally accepted it would be. Much less rampant.

That being said, its' privacy is entirely dependent on who stores your data and whether they give a shit.

[–] [email protected] 13 points 6 months ago* (last edited 6 months ago)

Nothing really. They did once put a scan on someone's IP after the authorities asked them to. But it was a court order. Makes sense.

I don't use them because I think Email is beyond saving anyway. 90% of our mail goes to or from Amazon, Google or Microsoft anyway. OpenPGP is not used by anyone, even Phil Zimmermann famously refused to use it. There is so much spam and phishing that most institutions no longer send anything of value by email, it's just a notification service for "please log in to our portal to view your message". Email is just so broken and the workarounds so feeble that it's beyond fixing.

Email as we knew it is just gone and done. I just use O365 because it's cheaper and offers me a lot more (like 1TB cloud storage which I use with Cryptomator). Proton Drive is too expensive for me and I like doing the encryption on the user-end anyway because that offers real end to end security. I applaud what proton are trying to do but it's too little too late and I don't want to use a special email client. If they want to promote privacy they should do it with something where that's still possible.

And for VPN I prefer mullvad anyway because I like the way they sell scratch cards on Amazon. And my password manager I self-host.

But really it's not a bad service if you can afford it and don't want to go for Microsoft and Google.
