With additional account protection, you can block access to your account for email programs. Retrieving emails is then only allowed via the webmail interface. Access with IMAP, POP3 and SMTP is not possible.

If you also activate two-factor authentication, criminals can no longer access your account, even if they have captured your access data (username and password).

This help article explains how to activate additional email account protection.
