Mozilla Accounts (formerly Firefox Accounts) is the account system for users to access hosted services provided by Mozilla.

A user can sign in with a Mozilla Account to any of their "Foxes" - Firefox on Desktop, Firefox for Android, and Firefox OS - to access integrated services such as Firefox Sync and Firefox Relay. They can also sign in to other Mozilla services such as Mozilla Monitor and Mozilla VPN.

For information on integrating a service with Firefox Accounts, visit the Firefox Ecosystem Platform.
