Online yoga teacher training is an emerging mainstream concept. This is in part due to the current circumstances & also the evolution of the existing yoga certification process. Many of the best teachers in the world have created their own online teacher training programs where you can expect the same level of teaching expertise from them at a fraction of the cost of an in-person retreat type yoga teacher training. This is a very exciting time in this space as the lower cost & wider accessibility opens the doors to many people who want to become certified yoga teachers but who haven't been able to in the past due to financial constraints, time constraints, etc.
