Salesforce provides several options for you to log in to environments. There are default login addresses for each type of Salesforce environment as well as the ability to create a custom URL or even redirect to Salesforce from any domain. Each of these options is supported in the Salesforce Feature Activation by changing the Login URL field.
Default Logins
Salesforce includes standard login URLs for either Production or Sandbox environments, and they areare mutually exclusive in that you cannot use the URL for Production to log into a Sandbox and vice-versa. These URLs are:
- Production: https://login.salesforce.com
- Sandbox: https://test.salesforce.com
The Salesforce Feature Activation page defaults to the Production URL.
Custom URLs
In addition to the default URLs provided by Salesforce, you have the option to configure Custom URLs within your Salesforce environment. Custom URLs use a hostname (provided by a Salesforce administrator) and look something like the following URL: https://customurl.my.salesforce.com.
Note that when using a Custom URL for either a Production or Sandbox environment, your administrator may choose to deny log ins from the default URL for that environment.
Custom Domains
Salesforce also allows you to redirect any DNS record to provide a log in to Salesforce. For example, https://salesforce.acme.com could be redirected by your administrator to provide a way for you to log in from a URL associated with your corporate or intranet environment.
