## Before you start testing...
Have you implemented [Instant Login with OAuth 2.0?](🔗)?
Have you configured your redirect URLs?
## Testing Individual Users
## Using sandbox user credentials
If you're using Clever's default sandbox district (auto-connected with your application):
Initiate a login. You can do this one of three ways:
Go to the district overview in your Clever dashboard. Copy the Portal URL, and after logging in, click your application's icon.
Go to the district overview in your Clever dashboard. Copy the Instant Login link and log in there.
Use a Log in with Clever button.
All sandboxes should be set up so the default credentials are:
Student: username and password are the student's `
student_number` (e.g., 377440)Teacher: username and password are the teacher's `
teacher_number` (e.g., 109663)School admin: username and password are the school admin's `
staff_id` (e.g., 12342)District admins may only be tested in [custom sandbox districts](🔗).
You can download the default district CSVs to test other users [here](🔗).
If you're using a [custom sandbox](🔗) district instead, you must configure and review your Single Sign On user credentials settings.
## Secure Sync only: IL debugging tools
In the Data Browser, open up the Detail View for a user where there is a link to log in as the user. This link sends a user-authenticated request to your app, so you can see what the user sees when they access your app through Clever.
This works for all user types that your application supports: students, teachers, school and district admins.
