## After providing the email ID

The messaging is kept neutral to hide if the user is already registered
or not. The email will contain more detail, if the account exist or not.

### Profile Page just after signup 
The user after clicking on the signup link in the email is redirect to
homepage. No dashboard is available as the user doesn't have applicant
role. If they click on the "profile" button they see this page with open
to update profile and setup a password and enable 2FA.

If the user decide to change the email, password is not asked if not
password is set, instead an email is sent to authorize the email change.
