Webmail does not login to inbox after enabling two-factor authentication

Symptoms

When the option "Open my inbox when I log in" is configured, RoundCube does not log in automatically when two-factor authentication is enabled.

Description

During a recent cPanel upgrade the "Open my inbox when I log in" configuration directive stopped working after enabling two-factor authentication for the account.

We've opened an internal case for our development team to investigate this further. For reference, the case number is CPANEL-49859. Follow this article to receive an email notification when a solution is published in the product.
