This allows to open login page in the popup (among other things). See https://issues.jboss.org/browse/KEYCLOAK-3322 .

See the ValidateOTP class for details. Marek > Cheers, > Thomas > > 2016-11-11 8:48 GMT+01:00 Stian Thorgersen <sthorger(a)redhat.com&gt;: > > This is not something we should add IMO.
