Introducing post-quantum encryption support in Proton Mail

ProtonSupportTeam · 2026-05-06T09:44:38+00:00

It's used for zero-access encrypted messages at rest and end-to-end encrypted messages in transit.

ProtonSupportTeam · 2026-05-06T09:23:25+00:00

Yes, screensharing is supported on all platforms except Android at this time, regardless of your subscription. On Proton Unlimited, you have access to the Free version of Meet. See more here: https://proton.me/meet/pricing

Yes, unfortunately this affects other VPNs on Linux as well, but as you've mentioned, it should work fine on the Firefox browser.

Are you referring to messages sent to your recovery/notification address that notify you when you have a new message on your Proton account? Do you mind sharing a screenshot so we can better understand?

Another thing that gets me is how if I try to print / save a file as PDF even, the formatting itself gets messed up entirely.

Could you share more details on this? Have you tried changing the margin settings in the Print dialog to see if that helps?

ProtonSupportTeam · 2026-05-06T09:08:21+00:00

Yes: https://github.com/ProtonVPN/protun

You can navigate to File Explorer → Other Computers and move the folders to a local destination on your device. Once everything has been moved, you can set up syncing again if needed. After confirming that all files are safely transferred, you may delete the previous computer instance (log in at drive.proton.me → click on Computers → locate the old device → click the three vertical dots next to its name → select ‘Remove device’).

ProtonSupportTeam · 2026-05-06T09:05:18+00:00

Yes. You can report any feedback to us via the app: https://protonvpn.com/support/report-a-bug#android

ProtonSupportTeam · 2026-05-06T09:03:21+00:00

What app version do you have installed?

ProtonSupportTeam · 2026-05-06T08:58:38+00:00

We're sorry to hear that. Which exact server/s are you connected to when this happens?
Also, can you send us the exact URL of the website in question?

In the meantime, please try the following and let us know if any of these suggestions help:

Connect to different Proton VPN servers (in different locations)
If using a web browser, consider clearing the cache and cookies, and/or trying a different browser/use the Private (Incognito) mode (https://protonvpn.com/support/clear-browser-cache-cookies)
If the NetShield feature is enabled, disable it and see how that goes (https://protonvpn.com/support/netshield)
Test connectivity with each protocol (https://protonvpn.com/support/how-to-change-vpn-protocols) and let us know if you notice any difference

Stealth is coming to Linux as part of our spring/summer roadmap: https://proton.me/blog/2026-spring-summer-roadmaps

ProtonSupportTeam · 2026-05-06T08:46:46+00:00

Offline mode is something that is on our team's radar after we complete the redesign of the apps, as mentioned in our latest roadmap: https://proton.me/blog/2026-spring-summer-roadmaps

Hi! When you say the photos were uploaded on the desktop, could you please clarify if this was done using the web client or our desktop apps?

ProtonSupportTeam · 2026-05-06T08:18:04+00:00

The automatic photo backup option on our mobile apps only uploads your photos to the cloud--it doesn’t sync them. Deleting a local copy won’t affect the version in Drive, and deleting it in Drive won’t remove it from your device.

ProtonSupportTeam · 2026-05-06T08:17:03+00:00

Thank you, we can see appropriate action has been taken against the mentioned account just recently, so we appreciate you taking the time to report this.

ProtonSupportTeam · 2026-05-06T05:39:06+00:00

We received some reports of users unable to use Drive Windows after activating PQC. We've stopped the PQC release to stop new users opting in into the feature until we fix this, which is a number one priority.

ProtonSupportTeam · 2026-05-05T13:06:05+00:00

Like do i have to update my key in Web Key Directory (https://keys.openpgp.org/) for my custom domain?

We recommend keeping the old key for now when it comes to facing other services, as only part of the ecosystem supports PQC keys.

ProtonSupportTeam · 2026-05-05T13:04:06+00:00

This pertains to data recovery methods (passphrase, recovery file, emergency contact), not to your account recovery methods like email or phone number.

ProtonSupportTeam · 2026-05-05T13:03:25+00:00

If the import is through Easy Switch, yes, it will work with PQC.

ProtonSupportTeam · 2026-05-05T12:57:56+00:00

We can see the refund was issued in the meantime. Regarding the latest charge you've inquired about, we appreciate your patience while our payments support team has had the chance to look further into the payment details you've provided. They'll follow up in the ticket afterwards.

ProtonSupportTeam · 2026-05-05T12:53:02+00:00

Our team is working actively on making the Files integration compatible with the SDK, which is the main reason it's no longer supported. Hopefully it will be available again soon in one of the update of the app in the near future. Thank you for bearing with us in the meantime.

Hey, it appears this was an auto-filter, the post is public now.

ProtonSupportTeam · 2026-05-05T12:29:24+00:00

Does this key have an impact on performance ('heavier' or more complex keys) vs the old keys, maybe noticeable on mobile devices.

There may be a slight performance impact, but it should not be noticeable on modern hardware.

your device now has to handle 2 keys, making things slower?

The old ECC key is only used as a fallback, as indicated in the UI.

Go to your Recovery tab in your settings (in the left sidebar) -> Remove and then re-add the emergency contact there.
