DifiByte Digi-ID Authentication:

Country config only give access to the basic servers even for Plus subscribers. This limits the number of IPs which are randomly cycled through by a Plus user and takes away a lot of incentive to upgrade.
It would be useful to have Plus specific country config files.

XRP is a crypto that could be implement in protonmail.
Advantages :
- secured
- low fees (nearly free)
- very fast (4seconds)
XRP will be a standard.

I would like to see an "Undo Send" feature, as found in Gmail. This is essentially a delay in sending, I guess, during which you can click an "Undo" link that appears in the bottom of the screen after you have hit "Send" on an email, for a varying amount of time that you can set (ex. 20 seconds). This gives you the chance to abort the send and tweak the message if, after hitting send, you realized you had forgotten something or you wanted to change the tone. It's something I find I use quite often for work.

A proton mail client protonmail that combine all the features and design from the proton web UI and allows the user to synchronise other mailboxes.

1 user, 1 domain = 48€/year
If you need 2 users, 1 domain = 150€/year
Why a so big price increase when you need 2 users ? Could you have an better offer, for example at 70€/year. Seems more logical.

Best regards

I use replicant operating system and not android, for evident ethical and security reasons.
I don't want to use google play, because I'm against google and don't trust them.

It will be very nice to put protonmail app in f-droid repository!

Allow us to set profile pictures that can be seen by those who receive our emails, proton and non proton users alike.

The Lightning Network is in beta, but it allows for instant payments (no confirmations) and almost 0% fees, provided the user has a channel open. You already accept Bitcoin... and the Lightning Network is a major upgrade to way people will use BTC to make payments. If you do it soon, you will also get a P.R. boost, as it will inevitably be mentioned in the Bitcoin media.

DANE (DNSSEC) would be hugely beneficial to the security and privacy of ProtonMail. DANE makes Man-in-the-Middle attacks practically impossible.

This is a necessary addition and should certainly be prioritized over-all, as it is at the core of what ProtonMail represents: privacy and security.

It's currently a feature available over at Tutanota (https://tutanota.com) and definitely sets it apart as an arguably more secure option, here's a great read on the topic: https://tutanota.com/blog/posts/dane-everywhere

Bitcoin transactions fees are now too much, and it may take up to a few hours for a transaction to be confirmed. There's a payment system, which is nearly same of Bitcoin, Bitcoin Cash. Its devs have a better vision "low fees, 1 block (10 minutes) transaction confirm time." If you haven't heard of it, here (https://bitcoin.stackexchange.com/a/58969/38618) you can see that many wallets support it.

Kind regards.

With the latest FIDO2 updates and all of the major web browsers supporting this (including Windows now for login!) will you be adding support for security keys like the Yubikey? This is a feature that I would REALLY like to utilize for MFA.

Would It is possible to know if the recipient open or read the mail? as https://www.mailbutler.io/en/ or https://mailtrack.io/en/

That would be great!
Thanks

Make a stealth version of your VPN so that ISP or telcos that block VPNs should not be able to tell by packet analysis that VPN is in use

Domain registration via Protonmail, Instead of pointing the domain there. Regester the domein via Protonmail.

In keeping with Protonmail's commitment to privacy and security I would like them to develop an app for Purism's upcoming Librem 5 smartphone. This would provide a genuine mobile alternative to Google and Apple.

I would love to see a proper ProtonVPN Linux Client with GUI that looks similar to the Windows version and with the same features. The current Linux client does not look good and it's too much and not plain and simple like with the Windows version. Is there anyone else that are not happy with the current client and want a better one?

Either allow multiple accounts to be open simultaneously in the iOS app or add option to switch between accounts without having to formally log out and log in between each swap.

Despite allowing multiple aliases for a single account, if you have a personal account but also shared an account (eg with a spouse) aliases don’t suffice. The idea of forwarding every email from one account to another is archaic, lose for user and lose for proton mail because you’ll be storing the same message twice unnecessarily.

Multiple account support is a basic feature for email apps.
