Microsoft has not provided an exact date of when the new security measures will go into effect for all users, but they will begin disabling Basic authentication for random customers beginning Oct. 1, 2022. The entire process is expected to be completed for all customers by the end of the year.
The reason behind the change is because Microsoft considers Basic authentication to be an outdated industry standard due to weak credentials which can be easily compromised. Modern authentication uses more up-to-date security standards making it more difficult for bad actors to compromise your account credentials.
