This is a must have for me, I don't want to use the Proton Mail app on my work computer without this feature

Been missing this feature since day 1 when u downloaded the mail trugh browser and made it an app!XD just saying privacy first! n00t c00l to n00t have iT! 0r the option to do so! if u have some1 sniffing in the hearth of ur sytem! XD Both on startup and after inactivity, PLZ!

This should be a no brainer to make. All your other products have this security feature, including android app for mail. Why don't you have this for the mail desktop app?

Please, Proton Team, add it already!
Use the same system as with Pass, it works perfectly.

This is a critical feature and i don't understand why this is not implemented by default. Please add it...

The Proton mail web app needs the same pin lock as the Pass web app, as soon as possible. This should be as standard for a secure mail app.

For users that count on Proton apps for security and privacy, I believe adding a feature to authenticate after minimizing, restarting or rebooting the system is critical especially if one happens
to forget to log off, anything could happen. At a minimum a PIN (like in Pass) or bio / 2FA. Much less burden than having to log off and on again.

Please add option to password-protect deskop mail app after some time of inactivity.
Ideally it could work just like Proton Pass.

Otherwise I suggest that first login per session requires greater protection (such as 2FA or whatever) and then you only need to enter password or 6-digit PIN (as in Pass) to unlock the app after inactivity.

Should be implemented on all Proton applications…ESPECIALLY MAIL!

This needs to be implemented across the board. Same for Linux and MacOS

This is the ONLY reason I don't use the desktop app. I simply don't understand how this wasn't implemented. I would imagine a windows machine is less secure than my iPhone and yet the phone has a pin function.

I know it's perfectly possible to have this feature as other windows apps do, so come on Proton, get this sorted. So disappointing from a security focused company.

For this reason, I've installed Tutamail to see what I think of it. Oh look, there's a lock feature. I will certainly keep Proton but looks like I'll also use tuta too.

Seems like a no-brainer. Same security level everywhere. And sometimes I don't carry my desktop with me.

It would be nice if the Proton Mail Desktop App could lock like the Proton Pass Desktop App.

Was shocked when I found out the app stayed logged in to my account even after restarting the PC. Please add the option to autolock the app after some time and also after turning the PC off and on.

Please add a setting to require a PIN or password when opening the Desktop App. This can be similar to the lock features on the Mobile App or Proton Pass.

It’s essential for Proton Mail to include an additional lock feature for the macOS app, not just for Windows. While macOS has device-level security measures like account controls and system locks, an in-app password or PIN lock would add crucial security. This feature would align Proton Mail’s protection with that of Proton Pass, which requires a password on each login due to the highly sensitive nature of its stored information.

Emails often contain equally critical data, so applying the same level of in-app security would offer users peace of mind, especially in shared or public environments where device-level security may not be enough. An optional lock within the app gives users more control, ensuring security standards remain consistent across all Proton applications and platforms.

Please add this feature to App on every platform, including Linux

Inactivity lock, passcode unlock, or even biometrics or key lock or unlock are needed for the desktop version. You should not need to worry about someone gaining access and then having direct access to your email.

It would be useful if biometrics could be used to unlock—for example TouchID on Mac.

Does anyone know if there's any progress with this request?
