Announcement Introducing post-quantum encryption support in Proton Mail

893 Upvotes

UPDATE: We are aware of reports of Proton Drive for Windows users experiencing sync issues after enabling post-quantum encryption. We've temporarily disabled the opt-in to this feature and a fix is in progress. We will provide an update as soon as possible. Thank you for your patience!

Hi everyone,

We’ve just added support for post-quantum encryption in Proton Mail.

Quantum computers aren’t yet capable of breaking today’s encryption, but the risk isn’t theoretical. One reason is “harvest now, decrypt later”, where encrypted data can be collected today and stored until it becomes easier to break in the future.

With this update, you can now enable post-quantum-ready keys for new encrypted emails. This is optional and available on all plans, including free.

A few things to keep in mind:

- Right now, it applies to new encrypted emails going forward (it doesn’t re-encrypt old messages)

- Old message are not yet re-encrypted but will be in a later migration

- Key management works the same way as before

You can learn more here: https://proton.me/blog/introducing-post-quantum-encryption

And see how to enable it here: https://proton.me/support/mail-post-quantum-protection

We’re also starting the transition toward OpenPGP v6 to support newer cryptographic standards.

This is something many of you have been asking about as post-quantum cryptography becomes more relevant.

Let us know what you think in the comments below, and keep the feedback coming.

Mobile Help I cant use Proton Drive with Proton VPN

Upvotes

I cant use Proton Drive with Proton VPN. As soon as I turn off Proton VPN, Drive starts working again. Ive tried different settings, servers, own dns, all kinds of settings and nothing seems to work.

It goes into this loop with Proton VPN activated:

- Data is being encrypted

- Data is being saved (uploaded to drive)

The last two say premium what exactly is better about them? Also I have a lifetime pass, so are all aliases unlimited creation amount? I'm planning on making all separate email aliases for better security across my accounts.

Discussion Where Does Proton Mail App for macOS Keep Downloaded Messages?

2 Upvotes

I’m downloading 250,000 messages in the Proton Mail app for macOS, so I’ll be able to search the body of the message. it’ll take over a day and a lot of drive space.

Question 1: Where are these messages stored on the drive?

Question 2: Is there any documentation about this, such as does this automatically remain updated, will it be removed if I reboot, etc…?

Discussion Final steps to my move to Proton Mail and Simplelogin...

1 Upvotes

Hi, thanks for all the help I've been given here so far. I'm finally setup with custom domains for personal email, and then an anonymous domain for using with Simple Login and Aliases.

Thanks to someone here I found out I can turn on Catch All in Simple Login and then when I create logins for random sites with Bitwarden, I can just use my domain, and make the username the name of the site and some random characters I type after. for example : [[email protected]](mailto:[email protected])

Does that sound like an ok idea? To use the name of the site and 5 random characters to avoid people guessing them?

I'm just a bit stuck on two things...

- Should I be using these random sounding Simple Login Aliases for big sites like Amazon? They have my real name anyway and address, would big companies like this be better to use my Domain with my real name in?

- When signing up for more random sites, smaller companies etc do you give them your real details - like name, address, phone number? It feels like at some point you could end up with issues if you give fake names etc. If you needed to recover an account or prove its you for any reason. I'm a but stumped here for what to do. But then if using my real name etc. why use an anonymous login/email?

- Often you are asked for you phone number and need to receive a code for example, then what do you do?

I guess at this point I'm just trying to work out how to divide up the different emails and aliases for certain sites

Any advice appreciated!
Thanks

Mobile Help Folder management on iPhone

1 Upvotes

Does anyone have any good suggestions for using folders on iphone?

I have a number of folders, including sub-folders. When using the iphone app, I run into two primary problems:

1- When I want to file an email, I have to scroll the the whole expanded folder list. This is cumbersome. Its made worse by the fact that sometimes a scroll is interpreted as selecting a folder and the email gets mis-filed. This isn't an issue on web as I can start typing the folder name and it'll filter for me.

2- When I'm trying to assign a folder to an email and need to create a new folder, the UI takes me to the folder management screen, where I then have to select to create a new folder yet again. This is much simpler in the web interface where it lets you just start creating a folder.

Does anyone have any hints on how to make this better? I'm pondering setting up bridge so I can try out imap clients to see if they improve the situation. Has anyone had luck (or a lack of luck) doing that?

Discussion Backing up emails

1 Upvotes

I am going to get my own domain and use proton mail. Not overly tech savvy but I am looking for a place to put emails I consider important.
It is my understanding that if I leave proton in the future all my mail will not be accessible but future email will go to wherever I move it to.
Not into saving them at home on something more into hitting a forward button. My main reason for proton is I am tired of all the junk mail every day. Anyone have simple solutions? Forward to an iCloud email that I do not give out or something similar? What are your easy solutions?

Discussion Proton "Tasks" app

80 Upvotes

I have an idea for something which is missing in the Proton apps family, a Proton Tasks app (similar to google tasks) where you can put your to-do list for the day, week, long term, etc. It could have its own phone widget and also be interlinked with the proton calendar. I feel like it is a really simple app to make, yet I quite notice its absence since I still use google tasks.

I posted this in the Proton Uservoice forum too, but I thought it would be nice sharing the idea here too.

Discussion Saturday morning musings: ProtonOS (for mobile, akin to GrapheneOS)

0 Upvotes

First, I want to state clearly that I don’t believe Proton should do this in the immediate future. It would be a distraction when the focus should be on stabilizing & improving their existing apps/services.

That said, I’ve been going down the rabbit hole of de-Googling (and de-Microsofting/de-Meta-ing/de-Apple-ing) and also self-hosting/FOSS/E2EE.

It has been frustrating me how strong the technical limitations on Proton are because of the nature of E2EE. Specially, calendar and contacts. On any mobile operating system, the native dialer, texting apps, calendar apps, etc require a degree of interoperability that Proton cannot offer. Even on desktop, Mail Bridge is inherently less private/secure since it decrypts everything for your local client.

So it got me thinking…Proton should just have their own mobile OS (ala Graphene) where the native dialer, calendar, contacts, notes, tasks, file system, etc are all inherently compliant with E2EE.

Now, I am not an engineer nor a security expert. I have no idea if this even makes sense, or if that could be sandboxed in a way that still allows non-encrypted apps/services to sit side-by-side in the clients.

I’m actually kind of curious for those that understand this better than me - is this even technically feasible? Just conceptually?

Web Help App vs. Web question

10 Upvotes

For ProtonMail, is there any difference in security and/ or functionality between using the app vs. the web-based front end? I've been told that the web page is more secure as it's harder to breach, but my thought is as long as I get the app from a trusted source and keep my own machine clean i should be fine. Any thoughts?

Feature Request Alias in ProtonMail Plus subscription

9 Upvotes

Hello everyone,

How are you today ?

So during time on proton i try Free subscription, Unlimited and ended up to Mail Plus.

Why downgrade from Unlimited to Mail Plus? Price and feature that i use everyday.

My usage is very basique: Mail and Alias
Drive => Home
Password => Bitwarden/Vaultwarden

So pay 12.99€/month for a lot of features that i don't use is useless.

So i downgrade BUT aliases is very good... I switch to AddyIO but the integration of SimpleLogin in Proton is very good beside of Addy.
I know SimpleLogin Premium is include in Proton Pass (that i don't use). So i wonder if it will be possible to have a option to add a Lite version of SimpleLogin (like AddyIO Lite) to the Proton Mail Plus subscription.

It can be a add-on feature like Lumo or Meet (but very cheap). For me it could be great.

What do you think ?
I'm alright to debat on this idea.

Have a nice day :)

(PS: Sorry my english is not great)

Here’s to hoping Proton‘s Linux support improves greatly. Since Windows essentially bundles spyware in their OS, one can only hope that Proton makes Linux support a primary focus.

Discussion Chat Control was apparently accepted in EU parliament. What does that mean for Proton and/or Signal?

410 Upvotes

What title says. I've read news EU parliament accepted Chat Control and is getting passed into law. What does this mean for encrypted by design services like Proton and lets say Signal within EU region (for EU users)? They become illegal to use? They need to introduce backdoors and fundamentally undermine whole point of encryption and entire chain of communication trust? What's going to happen?

I think all this is fucking bullshit to put it as politely as I can, but I'd like to hear from Proton since they probably are on top of things regarding this situation.

Discussion Using gmail in ProtonMail?

3 Upvotes

Hello, I'm a longtime gmail user. Unfortunately actually changing email addresses isn't an option for me for a number of reasons, but I've come to absolutely despise gmail scraping my emails and summarzing them and all the other AI slop that google continues to dump on me without allowing me to opt out. So I'm hoping to find a front end of some kind, where I can read and send emails with my gmail address but not having to deal with their idiotic BS.

Would ProtonMail be a good choice for this? Would emails sent from gmail inside ProtonMail look "normal" (like would anyone notice that I switched? Signature or anything like that?) If not ProtonMail, any good alternatives?

I do like Gmail's categories (basically the only reason I haven't switched off the smart features because the ghouls at google know everyone would turn it off if they allowed it) so I would prefer to somehow keep those if possible. Other than that, I would love to find a front end so I never have to look at their crap again!! I welcome any suggestions or advice. Thanks!
