We offer the option to link a PlayStation, Xbox Live, Steam, and Battle.net account to your Activision account. One of the benefits of linked accounts is the ability to log in to an Activision account with one of your linked first-party platform accounts. For example, suppose you forgot the password to your Activision account or no longer have access to the email address associated with the account. In this case, you can log in to your Activision account using the credentials for a linked PlayStation, Xbox Live, Steam, or Battle.net account to update your password or change your email address. This service is especially useful if your Activision account password gets changed without your knowledge.
 
Please note: You may also link Nintendo and social media accounts to an Activision account. However, logging in with these accounts is currently not supported.
