What is my Sandbox Log-in and Password?
Knowledge Article Number: 000005238
- Make sure you are logging in at the URL: test.salesforce.com
- The user name for the sandbox has the sandbox name appended. For example for ZZZ sandbox it would be username.org.com.ZZZ
- The password will be the same as it was in the production instance when the sandbox was refreshed. Salesforce does not alter passwords when we create Sandbox copies.
In any case that login fails, you may refer to Can't Login to Sandbox though Password is correct article for further information.
