How do I have Chrome prompt for password before opening?

Title of the thread basically.
I am using latest version of Chrome on Win 10 64 bit.
I remember there used to be an extension for FireFox...i think the name was ProfilePassword or something.
Is there any add-on for Chrome to enable this functionality?

I have not tested this one:

Set password for your browser ( chrome lock ) - Chrome Web Store

Thanks for your response...i just tested it..not a good one tbh...first off it doesn't mask the password :) and secondly it will prompt after displaying all the open tabs titles..ideally it should kick in when launching chrome for the first time.
I did look into the Chrome web store for other alternatives...doesn't look like there is a good one out there :)

thanks for LockPW mate...working great :)
