My Domain org login URL
Key Takeaway
A production org's My Domain login URL has the format https://MyDomainName.my.salesforce.com. This URL unlocks branding that the generic Salesforce login pages can't offer.
My Domain gives each Salesforce org its own subdomain, such as https://mycompany.my.salesforce.com. The My Domain name becomes part of the org's login URL and its application URLs. The My Domain login URL is the org-specific address that users and integrations can use to log in. It unlocks branding, login options and security controls that the generic Salesforce login pages can't offer.
The My Domain login URL format
The My Domain login URL uses a standard format, with the My Domain name as the subdomain. For a production org, the format is https://MyDomainName.my.salesforce.com. Users can log in with this URL in addition to the default Salesforce login URL, https://login.salesforce.com.
For example, in https://mycompany.my.salesforce.com, the My Domain name is mycompany.
