Chrome Version: 62.0.3202.82/9901.66.0 stable-channel Daisy,Candy and Reks
OS:  Chrome

What steps will reproduce the problem?
(1)Sign into User -> Go to chrome://settings -> Now under 'People' section click on 'Screen lock' option
(2)Now enter User Password in 'Confirm your password' dialog box -> Enable 'Show lock screen when waking from sleep' option
(3)Now at 'screen lock options' section  observe unnecessary 'PIN or password' option is seen
 (Please refer Video)

Expected: 'PIN only' option should be seen under 'screen lock options' section  
Actual:  Instead unnecessary 'PIN or Password' option is seen as already  we can observe 'Password only' option.

This is Non-Regression Issue as 'Screen lock' is introduced from M-57

Note: 
1.If 'PIN or Password' option is intended then 
on selecting that option -> observe 'SET UP PIN' button is enabled -> click on that button -> Observe 'Enter your PIN' overlay is seen and there is no option such as 'SET UP Password' button and  'Enter your Password' overlay

2.Issue is seen on latest M-64 also
