.appdomain nameIs a milestone in the domain name domain because this is the first TLD that requires the site to hold an SSL certificate and provide content over HTTPS by default, which means ifwebsiteInstead of providing HTTPS, but providing services over HTTP, users will not be allowed to connect to the site by default.
Google does not accidentally enforce HTTPS for its .app domain name, and the company has been promoting HTTPS as the default website connection type in Chrome. Google previously announced that starting in July 2018, Chrome will begin to mark all HTTP sites as "unsafe."
Google officially announced the launch of the .app TLD on May 1 when it opened the Early Access program and there are also paid items for users to register for the .app domain name. This strategy works well. According to statistics, in the early plans, more than 100,000 .app domain names have been registered, and with more domain name registrars registered on May 8, more domain names are registered.
Today, after entering the universal availability period, .app domain names can now be registered with any major domain registrar. Some of them even provide free SSL certificates to help promote domain names.
