The green badge means it’s an official authenticated developer of application.
The badge appears next to the name on an account’s profile. It is always the same color and placed in the same location, regardless of profile or theme color customization.
If accounts that don’t have the badge next to their name but that display it somewhere else, for example in the profile photo, header photo, or bio, are not verified accounts.
Authenticated developer can post reliable comment, activity and official announcement.
More Authenticated badges are still maturing. If you have more constructive suggestions, please @APKPure and tell us. Thank you!
