Century Internet Closes Basic Authentication, How to Use Microsoft 365 Email Smoothly?
Recently, many users have reported that their iPhone’s built-in Mail App cannot connect to Microsoft 365 email, constantly prompting for password input.
It has been found that this is because China’s Century Internet has closed the basic authentication feature and now requires users to use Microsoft Outlook to receive and send emails. In this article, sinokap will delve into this situation and provide you with suggestions to help you use Microsoft 365 email smoothly.
How to Solve this Problem?
In response to this change, we recommend that you take the following measures:

What is Basic authentication?
Basic authentication is a relatively simple authentication method that requires users to enter a username and password to verify their identity. Although this authentication method is easy to use, it has low security. Attackers can easily obtain user credentials through phishing, brute force attacks, and other methods. Furthermore, basic authentication does not support multi-factor authentication, meaning that users only need to provide a username and password when logging in, without any other verification.
Why did Microsoft switch to modern authentication?
To improve the security of user accounts, Century Internet has decided to close the basic authentication feature. After closing the basic authentication feature, users need to adopt modern authentication methods to access Microsoft 365 email. Modern authentication is an authentication method based on the OAuth 2.0 protocol, which provides higher security compared to basic authentication. Modern authentication supports multi-factor authentication, requiring users to provide additional verification, such as mobile phone SMS verification codes, when logging in. This way, even if attackers obtain a user’s username and password, they cannot easily log in to the user’s account.
Advantages of modern authentication
1. Supports multi-factor authentication
Modern authentication allows users to perform multiple verifications when logging in, such as username, password, and mobile phone SMS verification codes. This increases the difficulty for attackers to steal user credentials and improves account security.
2. Refresh tokens
Modern authentication uses refresh tokens that can automatically update user access tokens, ensuring access tokens are always valid. This reduces the risk of attackers using expired access tokens to launch attacks.
3. Conditional access policies
Modern authentication allows administrators to set access policies based on conditions such as device, location, and network. For example, administrators can set policies that only allow access to Microsoft 365 email from within the company’s internal network. This helps prevent unauthorized access.
4. Single sign-on
Modern authentication supports single sign-on, allowing users to access all related services with just one login. This simplifies the user login process and improves the user experience.
