Lock/hide a folder with a password or a security key

Hello,

I think it would be a good idea to be able to lock/hide Dropbox folders without necessarily putting them in the vault.

There are sensitive documents that we would like not to be accessible to everyone, without necessarily putting them in another place, and moreover, I may need to give access to my account to colleagues, so I think it would be nice to be able to lock/hide them with several security methods:

- Security key (Face ID/Touch ID/Physical security key)
- Specific password (or PIN)

+ You could choose to use the security method registered in the Dropbox account, or use another one.

Thanks
