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.

The new proton doc is great in that it is end to end encrypted. However I am concerned in case in the future someone compromises my password say in a breach or similar. I would like an extra layer of security where I could password protect individual documents so that the only way to access them would be to be signed into my account AND to have knowledge of the password for that document...

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.

I use proton drive to hold all of my Keys(Recovery, ssh, ect) just in case I get hacked I want to put a password on my "Keys" folder. Also I feel like everyone could benefit from this.

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

In case of a proton account breach, I would like to lock sensitive information inside my drive. Please add the ability to require a pin to download/preview/open a file.

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.

Replicated request but for windows - ie requested on both platforms so please combine to increase the weight of the votes:

It would be nice when making a new folder with in proton drive to have the option of password lock or have a 2FA lock. That way when you want to have a more secured folder for any reason we could double lock it for extra security and the peace of mind. So often when i am working and have the apps open and get called away that lets the app open for someone snooping or even if its shared by others and multi people are using the drive. If we could lock down a folder for just that more private business stuff it be nice.

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.

AT&AT - right, good point
