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.

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?

Also looking for a pin unlock feature for Linux desktop. There is a pin unlock feature in the Proton Pass extension for my browser... so how come there isn't one for desktop to keep logged in?

I would also add unlock feature to macOS desktop applications, like Proton Mail using the existing fingerprint functionality.

All MacBooks include biometric functionalities; it would be a great addition to have that.

Critical feature. Laptop is used by more familymembers and I don not want (kids) to give access to my mail. I can live with the that risk but worse is that the mail client gives access to absolutely all settings for the complete Proton account.

The ability to lock an encrypted email application is critical. I shouldn't have to logout of the app to know my email is safe.

Having an option to require a PIN anytime you open the ProtonMail Desktop App or after a certain period of inactivity is crucial for enhancing the security and privacy of user accounts. Here are several reasons why this feature would be beneficial:

Enhanced Security: Requiring a PIN adds an additional layer of security beyond just logging into the app. Even if someone gains physical access to your computer or if it is left unattended, they cannot access your emails without the PIN. This helps protect sensitive information from unauthorized access.

Privacy Protection: PIN protection ensures that your emails remain private even if someone briefly gains access to your computer. It prevents casual snooping and maintains confidentiality, especially important if you work in shared spaces or have sensitive correspondence.

Compliance and Regulation: In certain industries or professions, there are regulatory requirements for securing email communications. PIN protection can help meet these standards by ensuring that unauthorized individuals cannot easily access sensitive information.

Convenience with Security: While strong passwords are essential, they can sometimes be cumbersome to enter frequently throughout the day. A PIN requirement strikes a balance between security and usability, offering a quicker way to protect your account while maintaining accessibility.

Preventing Unauthorized Access: Users may inadvertently leave their desktops unlocked or unattended, especially in busy environments. A PIN requirement mitigates the risk of someone else accessing your emails during these moments of vulnerability.

User Control and Customization: Providing the option to enable or disable PIN protection gives users control over their security preferences. Some users may prefer the convenience of instant access while others prioritize heightened security.

Adapting to Desktop Usage Patterns: Desktop environments often involve longer sessions compared to mobile usage. Requiring a PIN after a period of inactivity aligns with typical desktop usage patterns and ensures ongoing protection without unnecessary interruptions during active sessions.

In conclusion, implementing an option for PIN protection in the Proton Mail Desktop App would significantly enhance security, privacy, and compliance for users. It provides a flexible yet effective means to safeguard sensitive information and maintain control over access to email accounts, especially in diverse and dynamic usage scenarios.

The lack of app locking and presumably local encryption is the sole reason I do not use the desktop mail app; I use Proton Mail exclusively in my browser, which I have set to clear all browsing data on exit. I don't like the idea of having my email account unlocked all the time. I would love to see local encryption implemented for the desktop mail app.

Lock with Security key would be great. Just touching my biometric key every time would be a great compromise between safety and time saving.

A timed lock could also solve one of my real dislikes of the Proton Mail app (Windows).

If you close the app without logging out it can be opened again without a password. This behaviour still exists if you shutdown the laptop/PC. When the laptop/PC starts up again you still don't require a password to open the Proton mail app.

On a corporate desktop this would be unacceptable for security reasons.

All Proton apps (especially Proton Mail) should should have a pin option with a user set timeout. If pin tries fail several times then require a full user id and password to get back into the app. When the pin timeout expires then require a pin re-submittal.

Very convenient, as Proton Pass is now.

Just like Thunderbird, there needs to be a passcode lock to add extra security layer.

Besides using a PIN, it would be nice to unlock with biometrics as well.

So I've looked at what has been said here. I agree should have it work like the Android app where I can set a pin. Maybe since I'm on Linux, my reason for wanting it a little different. For me the app just stays logged in and just loads up every time I open it. Convenient, yes, but there needs to be a lock for security reasons. I don't even care if it reprompts for the mailbox encryption key.

I just don't understand why an encrypted email service would be defaulted to auto load with no password request?? Getting in to windows is easy, so why not adopt the same thinking as phones? Even if it was a text or auth app at login, I'd rather have the choice of having that additional inconvenience for my own peace of mind. If this doesn't change, I will have to have my emails diverted to some other service, Criptext has this, and it works perfectly. 4 number pin.

I'd like to chime in and say ALL Proton apps -- desktop or mobile or whatever -- should ideally support a separate PIN. Maybe even support for a duress PIN.
