Hi @Guanda Li , if you're using an external identity like indeed, you need to add it as an identity provider. For your second error, to use a Microsoft account you need to make sure that it is a personal Microsoft account and not associated with an organization. You can create a new personal Microsoft account if you don't already have one.
Please let me know if you have any questions and I can help you further.
