Hello,

 What I need is to create a system to allow the access to my customer´s web apps. 

For Example, Customer "X" has this MAIN login access: login user: customer-x@mydomain.com login pass: 123456

 This customer, has bought the following services with their unique 'logins' for each one:

- Email Marketing (login user: 1@mydomain.com - login passw: x123456)
- Landing Page (login user: 2@mydomain.com - login passw: y123456)
- Web Optimizer (login user: 3@mydomain.com - login passw: z123456)

Well, what I need is the following: 

 1) This customer access with her main login access (login user: customer-x@mydomain.com -login pass: 123456) from a form that is going to be the point of access for all the customers.

2) When this customer is logged-in, then appears all the services that are asigned to this particular customer like this for example:

- Email Marketing - Click here to access to your account (Your keys are: 1@mydomain.com / x123456)
- Landing Page - Click here to access to your account (Your keys are: 2@mydomain.com / y123456)
- Web Optimizer - Click here to access to your account (Your keys are: 3@mydomain.com / z123456)

And just clicking in the link of each service, she can access to that web app automatically. Fill and Submit the App Form Access. 

3) I use Zoho CRM for managing my costomers, Could it be integrate with this app ? May be you have better ideas for this solution. Waiting for them, best regards
