From CNET: Google Messages are now encrypted by default when messaging between Android devices, the company said in a blog post on Tuesday.
Google Messages have had an option to encrypt your messages in settings, but now it's set to default.
This means that when sending texts between two Android devices, including in group chats, outside actors won't be able to view or monitor your messages. Encrypted messaging is already default on instant messaging services like WhatsApp, Signal, Telegram and Apple's iMessage.

For encrypted messaging between Android and iPhone, it's best to use a third-party instant messaging app instead.
