‘Grant Account Login Access’ is a standard Salesforce feature which allows Salesforce users to give their Company Administrator, Salesforce Support and Managed Package Providers the ability to login as them without the need to access their personal login details. We recommend you grant login access to MessageMedia when you require support.
