Protect your phone with a sign-in PIN
Set up a sign-in PIN to make sure nobody else can unlock your phone. In addition, when you
have set up a sign-in PIN, your phone asks you for this short PIN instead of your Microsoft
account password when you change some security settings or buy an app from Store.
1. Swipe down from the top of the screen, and tap All settings > Accounts > Sign-in
2. To set the sign-in PIN, under PIN, tap Add.
3. If your phone asks you for your Microsoft account password, type it in.
4. Type in a PIN (at least 4 digits).
5. Under Require sign-in, set the length of time after which the locked phone requires a sign-
in PIN to unlock it.
Keep the sign-in PIN secret and in a safe place separate from your phone. Make sure you have
a Microsoft account on your phone – if you have an account and you forget the sign-in PIN,
you can reset your PIN at account.microsoft.com using the Find My Phone option. If you
forget the sign-in PIN and cannot recover or reset it in any way, your phone will require service.
Additional charges may apply, and all the personal data on your phone may be deleted. For
more information, contact the nearest care point for your phone, or your phone dealer.
