This drive comes with a secure login hardware system and when you plug it in you will see a choice of emulator/"activator" interfaces for logging into a PC, Mac or device. I usually use it on a Macbook or desktop PC, but I've also visited guest PCs and what happens is you plug it in and you see the initial selection of apps to login to the platform. Select your OS, click and enter your password - whatever password you originally set from your computer/device, once you do this your password will be hardwired to the drive and you can access it from anywhere - if you you have a password. By the way, setting up hardware encryption/security is optional. But it's very simple, and it works really easily on my computers and the computers I've logged into while traveling. Same routine. Open the login screen, enter the password, you are. The password is required each time it is reset. Excellent basic mobile security. There is a known oddity for the Mac, despite being fully compatible. The first time you connect or eject, you may see a pop-up in the upper right corner saying that the drive was not ejected correctly (last time). Maybe on Windows "safely remove" avoids this, but on a Mac you're more likely to see it. Don't worry if you don't transfer data by disconnecting it from the network. (On a Mac, I "eject" and it looks fine, but it still gets the safe eject tooltip.) What else can I say? I know there are several reputable manufacturers of 250-500 GB portable SSDs worth considering. (As a scientist, trust me, I read all the reviews and looked at the "data", but as a typical computer user, I chose based on things like form factor, price, and past experience). So this is my third Samsung T (2 "3" and one T-5 now). I had no problems with any of them (thus my collection has grown). They are fast, reliable and practical between different interfaces, portable protection and cable/interface selection. I am satisfied!
