Ability to lock folder (or folders) to prevent unwanted access in case of PC open and other family members use it or in case of PC hacked, files would not be available for locked folders. The only reason I still use OneDrive, not saying their solution is the best, but it does the job.

This feature will add more privacy to sensitive information. I.E medical records

I'd like to be able to lock folders behind passwords, and prevent the files inside said folders to appear in the search feature, but they would appear if the folder is unlocked.
That would be extremely useful for family usage of Drive, as sensitive data is safe from other family members.

I believe that there are many justifications for this feature now. Hopefully, Proton can begin working on this soon?

I would love to see this. This should be similar to how Microsoft does it with OneDrive Personal Vault. When you go to access your vault it prompts for re-authentication...in the case of OneDrive, it just askes for your MFA code.

need this. both windows and mac. on ios for example, the app can already be set to require a faceid or pin. it should be the same on windows or mac.

i'd do cryptomator. it's redundant. but I can't open a cryptomator volume stored on proton drive on ios.

Random, not having a PIN aid a security risk. Also this feature already exists (Menu > Settings > App PIN)

request: add PIN to access protondrive on phone that is separate from the phone PIN.
use case: i do not have a lock on my phone. if i loose my phone i don't want anyone to access my protondrive.

While I know you can set up a pin/password for proton pass already, I wish there was a way to add an extra layer of security for vaults that have personally info. Plus since you can view all vaults, if this is added then the locked vault will only show up if you put in the password of pin.

The security requirements for accounts in vaults differ. Those used for daily tasks should be easy to use. Those used for administrative tasks with high privileges require increased protection but are used less frequently. These accounts should have additional security measures, such as an extra password or security key.

Yes it would be interesting to have something similar as the personal vault in Onedrive !

My family may need to access my account one day, and I don't want them to see what is on my Proton Drive. We have a difference of opinion on various issues-which the content of my drive reflects, and I don't want them to ever know how I feel. I don't share my account with them, but its always possible they may need access in the future.

This would be an amazing feature to have!

One of the things that still prevent me to move away from OneDrive, that would be awesome to have it!

Please add this feature!

be able to set a password is a priority like a private internal vault password to add a double layer encryption on some specific folder! 3 failed attempts should require full login again. or where's the privacy?

I would love to have that feature, too. Preferably with a whole folder, not only a file.

This is very important

This is SO important and most services already have something like this. I'm very surprised it isn't already implemented. Please do this!!

This is an important feature, that adds extra security to very important files (id, passport, medical records) when a device is stolen, which is very common in some places of the world. Something that would work as well is compatibility with cryptomator. It would be nice to be able to use cryptomator synced with proton drive in my iPhone.
