[SalesForce] Other users in Sandbox cannot log in

I have a Professional edition of SalesForce where I have one Sandbox license. I created one Sandbox and I'm able to log in as the administrator but other users cannot log in to the sandbox.

They are using the url test.salesforce.com to log in with their login as testuser@testaccount.com.dev and the same password as they had in the production system.

Is there something that can be done to fix this or is this because only one user is allowed to log in to the sandbox?

one straightforward approach is to send a reset password for those users who are having issue logging inot sandbox. This can be done easily when you actually logged into sandbox as sys admin. Simple and easy.

so, go to Users, select the users you want and click Reset Password.
