i wish you will be made secure the apps or files with an nativ option on startup the luncher. crypted apps or appfile with an password.
nobody how find my usb-stick should read my personal app-data (browser, chat...)
i know i can use use the portable veracrypt but thats not comfortable for the PortableApp.com Luncher... i think that is a Job for the PortableApp Luncher!
Password protection preventing you from launching an app or 'hiding' your portable app folders without actually encrypting them is fake security. The apps you find online to 'lock' folders nearly always use simple tricks to hide them from Windows Explorer but you can just open them up at the command prompt or within a third party file manager.
I may in the future incorporate a simple version of this into the platform but it will be clearly marked as security by obscurity and not actually secure. The only way to truly secure your files is to encrypt them either with software like VeraCrypt or a hardware-encrypted flash drive.
Sometimes, the impossible can become possible, if you're awesome!
