I have launched a YouTube series explaining the various concepts of OAuth 2.0. It is titled “OAuth in 2 Minutes.” With each installment consisting of 1 video of about 2 minutes, the series explains various OAuth concepts in a way that even non-engineers can understand.
The 1st installment covers the basic concepts. Anyone who has used a subway or train will understand them right away.
The audio is in English, but Japanese subtitles are available, so please turn them on when watching.
