In this example, registration (keycode confirmation and account activation) is part of the ecommerce platform. This includes most of the administrative functions (set PW, retreive keycode, password, etc.)

On the AHSP.com site, "MyAccount" allows users to manage passwords (limited to pw - kaycode should not be managed here as well).

When user changes password on AHSP.com, data transfer should keep the ecommerce user DB current, and vice versa.

Issues: Complicated, more expensive, more risk of technical difficulties, cross domain data transfer is tricky

In this example, registration (keycode confirmation and account activation) is part of the ecommerce platform. This includes ALL aministrative functions

On the AHSP.com site, "MyAccount" links to "MyAccount" environment on ecommerce platform. User can change account parameters.

Verified accounts link (redirect) to PW protected companion web site on AHSP.com. AHSP.com can be passive (verification happens on ecommerce). How does AHSP.com know an incoming link is a legitimate registered user

Issues: not very secure (easier for non-registered users to gain access to the password protected site)
