k4u1r (k4u1r) asked a question.
In our organization users login to Okta using their loginname (e.g. jdoe)
Most of our applications however use the e-mail address as the username.
Is it possible to login to Okta using the loginname as well as e-mail address so that users can use either?

You can customize the "app username(s)" by leverage okta expression language.
