Need this for extra level of security if mobile phone is lost and someone managed to get access to proton drive

Intuitively I am experimenting with ideas of "pairing" Proton Drive with Tresorit. Both zerotrust. Both Swiss based.

The lack of this feature in Proton drive is the main reason I still use onedrive, which works very nicely with the "personal vault".
When this feature is implemented I'll upgrade my Proton pass and switch to Proton drive!

Not sure if this is the same issue, but there's certainly an overlap. I just installed the Drive app. I keep my private documents in a Veracrypt drive, which I only mount when I need it. I figure that if my laptop gets stolen I've got an extra level of security against scoundrels getting my data. But the Drive app will not allow me to assign a folder on this drive as my sync folder - it says "Drive type not supported".

Please Proton - is it possible to support this type of Drive?

I think this might put some users at ease when you sync with your devices. Even if you have your folders synced to e.g. your phone, someone with access to the unlocked device can't open certain very private folders without an extra password. Currently I use verycrypt and picocrypt for that, so IDK how important this feature really is, but might be good to have.

Don't care about this at all, what's the use exactly? Proton already uses Zero Knowledge end to end encryption and you either trust that or not.

I have recently joined Proton drive and love it so far but I am really missing a "lock" option to be activated to folders I deem it necessary for. At minimum a simple pincode would do :)

This is the most important feature missing from Drive.

Microsoft implemented this nicely in OneDrive. They call it a personal vault. You can't see the folders in the personal vault without "unlocking it" with a separate passcode. When the vault is locked, the items in the vault don't appear in OneDrive searches.

If someone happens to be shoulder surfing, they can't see the folders/files in the vault.

While we're waiting for Proton to indicate that they've seen this...

I've used Cryptomator with Proton Drive to get much of the same effect. It would be more convenient if Drive just too care of it, but it works.

I would want this, but also the ability to hide this folder in the mobile apps.

I would love to see this. Adding an extra password, but also make sure that the contents are not synced to whatever computer you have the app installed on. What is the point of having the folder password-protected if it will just be downloaded to a computer

I feel a custom timeout option should be included so that vault locks after X minutes of inactivity.

I could almost see a Ghost Folder feature like Cryptee has.

Where you can Ghost (hide) a folder. It's then hidden and essentially unknown to anyone. However you can unGhost it by typing the exact folder name.

I get what is being requested here, and it's a good idea, but you can already password/fingerprint lock the Android app, so this feels like a lower priority than say, porting the existing feature to the web app.

Didn't realise what a Vault meant. I created a duplicate of this here with a bit more detail on features.

I would like the ability to set a password onto any folder not just a vault

Yes, it becomes especially useful as proton gains more customers who have different use-cases

There is overlap between this idea and

Perhaps this idea can be merged with it to consolidate votes.

The idea here is to insure extra privacy protection that prevents any other person-who has access to Your Trusted Computer -from accessing One's important or private materials in The Proton Drive.
