ProtonMail v3.16 Release Notes

The latest version of the ProtonMail webapp includes three new features for improved security and convenience.

ProtonMail version 3.16 now offers elliptic curve cryptography, an optional link confirmation warning to guard against phishing attacks, and an “undo move” feature for those moments you accidentally send an email to the trash or the wrong folder.

Elliptic curve cryptography (ECC)

ProtonMail joins a growing number of tech services offering elliptic curve cryptography. ECC is a more modern alternative to RSA that allows you to use smaller keys while accomplishing the same level of security. If you choose to upgrade your mailbox to the new ECC keys, you may notice slightly shorter encryption times.

Because of the unique nature of elliptic curves, ECC saves processing power (allowing you to log in, load, and send emails faster), memory (freeing up space for other apps), and energy (longer battery life), especially on mobile phones.

To switch to ECC and to learn more about how it works, check out our recent article.

Link confirmation

Link confirmation is a new security feature in ProtonMail version 3.16 that can help you identify possible phishing attacks. While link confirmation is enabled, whenever you click on a link in an email, a window first pops up asking whether you’re sure you would like to visit the URL. Phishing emails are the most common method for hackers to deliver malware or gain access to your account. Link confirmation helps you avoid accidentally landing on a malicious webpage.

You can learn how to enable and disable link confirmation in the webapp, Android, and iOS here.

Undo move

Here’s something that’s mildly annoying: when you hit “move to trash” but you meant to click on “move to archive”. We’ve added a new undo move feature for just such occasions.

Instead of hunting for it in the incorrect folder and moving it, it’s now easy to undo the action by clicking on the UNDO button at the top of your mailbox. The button works when you send an email to any folder and restores it to the previous folder. For example, if you move an email from your Spam folder to your Inbox, you can quickly move it back to Spam. But click fast: the button disappears after a few seconds.

We’re excited about these new updates and we look forward to hearing your feedback!

Best Regards,
The ProtonMail Team

  • What is new here? All these features were in the variour iterations of 3.15. There doesn’t seem to be anything new here at all, this is very confusing.

  • Undo move is a nice feature, but I think the real issue is a design mistake: the archive button shouldn’t be in between trash and spam. It should be over with “Move to” and “Label as”, or separate altogether.

    • Our calendar is under active development right now. It is very challenging to build in a completely encrypted way, that is why it is taking longer. We will have more to share about this later this summer.
