What does the User/Password Authorization in Mail Operation require?

User/Password Authorization in a Mail Operation specifically requires login credentials from the user. This means that to access an email service or perform actions such as sending or receiving emails, the integration needs valid username and password information. This type of authorization ensures that the user has the necessary permissions and access rights to interact with the email server.

In the context of email operations, providing the correct login credentials is essential for establishing a secure connection and allowing users to manage their emails effectively. The other options, while relating to broader security or operational aspects of email handling, do not directly pertain to the basic authentication requirement, which focuses solely on the need for the user's credentials to access email services.
