The Samsung Reactivation Lock feature makes it difficult for anyone else to use or sell your Samsung device if you lose it.

What is Reactivation Lock?

With Reactivation Lock enabled, your Samsung Account ID and password are required before anyone can reset your device. This feature can help you keep your device secure, even if it's in the wrong hands. You can improve your chances of recovering the device using the Samsung Find My Mobile site, and even erase your device remotely and still prevent from reactivating it without your permission. All you need to do is keep Reactivation Lock turned on and remember your Samsung Account ID and password.


Reactivation Lock has the following requirements:

  • A Samsung account
  • A supported device (check Samsung's website for more information)
  • Reactivation Lock turned on in Settings > Security

You need a second device or computer to use Find My Mobile to locate or secure a device.

Returns and exchanges

Returning or exchanging with Reactivation Lock active doesn't void your warranty. Just remember to always turn off Reactivation Lock and erase your device before selling or giving it away to ensure the new owner can activate and use the device.

    1. In a web browser, visit and log in with your Samsung Account ID.
