What is required when using two-factor authentication with a Mail Connector?

When using two-factor authentication with a Mail Connector, an application password is required to access the email account. Two-factor authentication (2FA) adds an extra layer of security by requiring not only a password and username but also something that only the user has on hand, such as an app that generates a secure code.

In cases where 2FA is enabled for an email account, the regular password may not be sufficient for automated processes or applications trying to connect to the email server. Instead, an application password, which is a special code generated by the email provider, allows such services to authenticate without requiring the additional second factor of authentication every time. This is particularly common in business and enterprise settings where security is critical, and applications need to send or retrieve emails programmatically.

The other options do not align with the needs of integrating securely with an email account when 2FA is implemented. A dedicated mail server does not directly relate to the requirements of authentication methods. A secondary email for verification is a process commonly used in account recovery, not for allowing application access. Additional licensing for enhanced security does not pertain to the standard requirement of an application password when using 2FA with a Mail Connector.
