Can I log in as a different user/role?

Can I log in as a different user/role?

I am the administrator who is setting up Zoho CRM for my organization. What I want to do is view the system as a Regional Sales Manager or Sales Rep to make sure it's working as desired. I would also want to do this for training purposes. 

Is there a way I can log in as a Regional Sales Manager or Sales Engineer?

Thank you!
