How to open your locked Android device (your mobile number is continually access)

How to open your locked Android device, when your mobile number is continually working in the same device..?
1.    Go to the Accounts Recovery Page.
2.    Select one of the available options.
3.    Note that if you choose forgotten “I don't know my password", Google will require    your Google email address.
4.    Remind it; enter the same email address you used when you registered your phone.
5.    If you can't remember it, you can reset your password from a device you signed in with    recently, even if it is not the device that is locked.
6.    Careful! Google actually recommends using another device that is not locked.
7.    In this case, even if you are resetting from another or unknown device, click "Yes continue".
8.    If you can remember any recent password you can enter it.
9.    If not, click "I don't remember".
10. You will then be asked to enter your mobile number.
11. Google will then send a verification code to your number.
12. Enter the verification code in the field and click "continue".
13. Now enter a new password and click "Reset password".
14. Use the new password on your device.
