Is the following scenario possible?  
Assumptions:  
I have 2 applications (2 different Client IDs) and I use one Auth0 Username-Password-Authentication Database (central user base). and new universal login

The user logs in to Application A - is redirected to Auth0, puts the login and password, and enters Application A. Then the user enters the URL in the same browser (or clicks the link) to Application B. The login screen appears again ☹  
I would like the user not to have to enter login and password again. Is it possible that application B (different ClientId) gets the application A token?

Hi @kubasz,

Yes this is possible. Take a look at this article:

> **[How to Implement Single Sign On](https://auth0.com/learn/how-to-implement-single-sign-on)**
>
> Implement Single Sign On to allow users to login to multiple systems with just one set of credentials.

Let me know if you have any questions.
