How can I find a specific text then select anything between the next set of quotes using regex?

Question

I have a string that looks similar to the below

..."lastName":"","password":"somepassword"}

I want to be able to search the string using regex for password then select the actaul password in the next set of quotes. i.e the regex should select somepassword

I was able to find a match for password using the following regex but need then have a mechanism to select the password value

(?:^|\W)password(?:$|\W)
