Domain lock is like a lock that keeps your toy safe so nobody can take it away from you.
A domain is the name that you give to your website, like "www.mywebsite.com". When you buy a domain, you want to make sure nobody else can take it away from you or mess with it. That's where the domain lock comes in.
Think of the domain lock like a lock on your toy box. It keeps your toy safe and secure, just like the domain lock keeps your website safe and secure.
When you put a domain lock on your website's domain, nobody can make any changes to it without first unlocking it. This way you can make sure nobody takes your website away from you or messes with it without your permission.
So, if you want to make sure your website's domain stays safe and secure, you should always put a domain lock on it. That way you can play with your toy (website) without worrying about somebody taking it away from you.
