[baasio]

The email registered on my atlassian id is going to be unavailable soon.email is jeon.gyuchan@kt.com.
So I want to change my email address, but I can't find user interface for changing email.
How Can I change email address.
If possible, I hope set email address admin@baas.io not jeon.gyuchan@kt.com

After research it turned out: it is not possible because at Google external users are only contacts, not 'real' users with a password.

If non-domain users need to be handled its only possible with f.e. Okta or LDAP, see https://support.atlassian.com/provisioning-users/docs/configure-user-provisioning-with-an-identity-provider/
