Samsung’s latest Android 5.1.1 software is bringing Guest Mode to the new Galaxy S6 and S6 edge, allowing owners to set up a secondary account for other users. And if you’re on T-Mobile in the U.S., you can already get your hands on it.

Guest Mode was first introduced to Android smartphones with Google’s first Lollipop update last fall, but it was not included in Samsung’s initial Lollipop firmwares. Now the South Korean company is introducing it with Android 5.1.1.

It’s an incredibly useful feature for a lot of users because it allows you to set up a secondary account on your device for others to use. So if your kids like to play games on your phone, or your other half is always borrowing it to make calls, they can use the Guest account — or you can set up a profile just for them.

What’s great about a Guest account or secondary profile is that they’re completely separate from your primary account; they cannot access your apps, photos, videos, and other data — and they can even have their own passwords or fingerprints.

If you’re an S6 edge owner on T-Mobile in the U.S., you can get your hands on Android 5.1.1 now; it’s already rolling out over-the-air. If you’re on another carrier or you have a Galaxy S6, you can expect it to be available over the coming weeks.
