This includes avoiding the use of impermissible personally identifiable information, and providing appropriate notice of your use of identifiers in your Privacy Policy. Your user ID must not contain information that a third party could use to determine the identity of an individual user. For example, you cannot use a user's email address or social security number as a user ID.\n\nThere are many ways you can construct valid user IDs. One approach is to use an\nidentifier you assign and only you can track back to an individual user. For one\npossible example, consider a hypothetical mobile game developer,\nAwesomeGameCompany, that has their own internal `AwesomeGameCompanyID` that they\ncreate for every user. If it isn't possible for an outside organization to track\nthat `AwesomeGameCompanyID` back to the original user, they might consider using\nthat `AwesomeGameCompanyID` --- or, better yet, a hashed version of\n`AwesomeGameCompanyID` --- as the user ID value for Analytics.\nThis would then allow them to calculate values such as a user's total spend\nacross all of their games.\n\nSetting a user ID is never required for Analytics to work correctly.\nIf you're only interested in finding events belonging to the same user for the\nsame app on a single device, you can use the `user_pseudo_id`.\nThis value is generated automatically by Analytics and is\nstored within BigQuery for each event.\n\nSetting the user ID\n\nYou can set a user ID with the following method: \n\nSwift\n\n\n**Note:** This Firebase product is not available on the macOS target. \n\n```swift\nAnalytics.setUserID(\"123456\")\n```\n\nObjective-C\n\n\n**Note:** This Firebase product is not available on the macOS target. \n\n```objective-c\n[FIRAnalytics setUserID:@\"123456\"]\n```\n\nAndroid \n\n```java\nmFirebaseAnalytics.setUserId(\"123456\");\n```\n\nWeb \n\n```java\nimport { getAnalytics, setUserId } from \"firebase/analytics\";\n\nconst analytics = getAnalytics();\nsetUserId(analytics, \"123456\");\n```\n\nWeb \n\n```java\nfirebase.analytics().setUserId(\"123456\");\n```\n\nDart \n\n```dart\nawait FirebaseAnalytics.instance.setUserId(id: '123456');\n```\n\nUnity \n\n```c#\nFirebase.Analytics.FirebaseAnalytics.SetUserID(\"123456\");\n```\n\nC++ \n\n```c++\nanalytics::SetUserId(\"123456\");\n```\n\nAfter setting a user ID, all future events will be automatically tagged\nwith this value, and you can access it by querying for the `user_id`\nvalue in BigQuery. Adding a user ID will not affect any\nevents previously recorded by Google Analytics.\n\nTo find out more about accessing Analytics data in BigQuery, please see\nthis [development guide](https://cloud.google.com/solutions/mobile/mobile-firebase-analytics-big-query)."]]
