Difference between Modern Authentication and Basic Authentication:

Basic Authentication is a method of authenticating users in which a user provides a username and password to access a system or service. It is a simple, widely-supported method of Authentication, but it is considered less secure than other methods because it sends the user’s credentials in plaintext.

Modern Authentication is a more secure method of authenticating users in Microsoft 365. It uses multi-factor Authentication, which requires users to provide more than one form of identification, such as a password and a security token, to access a system or service. Additionally, Modern Authentication uses the OAuth 2.0 protocol, which provides better security for user credentials by encrypting them during transmission. By default, Modern Authentication is ON in Microsoft Office 365 if your tenant was created after October 2019. But if your Office365 account is created before 2019, you need to enable Modern Authentication.

In summary, Basic Authentication is a more straightforward, less secure method of authenticating users, while Modern Authentication is a more secure method that uses multi-factor Authentication and encryption of user credentials.
