You can add users at the account, property, or view level. The level at which you add a user determines that user's initial access. For example, if you add a user at the account level, then that user also has access to all the properties and views in the account, with the same set of permissions. If you add a user at the view level, then the user has access to only that view with the permissions you provide. You can change the level of access and permissions for a user at any time. (Learn more about permissions.)

Users are identified by their email addresses. You can add only users whose email addresses are registered in Google accounts.

To add or modify users, you must have the Administrator role at the account, property, or view level. You can add or modify users at each level for which you have permission.

To delete users, you must have Administrator role at the account level. You can delete users only at the account level. Any user with permission can delete any other user. As a safety measure, if you are the last user who has the Administrator role, you cannot delete yourself.

Add users

You can add as many users as you need. To add a new user to an account/property/view:

1. Sign in to Google Analytics.
2. Click Admin, and navigate to the desired account/property/view.
3. In the Account, Property, or View column (depending upon whether you want to add users at the account, property, or view level), click Access Management.
4. In the Account permissions list, click +, then click Add users.
5. Enter the email address for the user's Google Account.
6. Select Notify new users by email to send a message to the user.
7. Select the permissions you want. Learn more about permissions.
8. Click Add.

Edit users

You can edit the permissions for any user at any level in an Analytics account. For example, if you have given a user the Viewer role for only a single view, you can subsequently also give the user the Editor role for only that view. Or you can give that user the Editor role at the property level, and thereby also give that user the Editor role for every view in that property.

You can give a user more permissions as you move down the account hierarchy, but you cannot give a user fewer permissions than you assigned at higher levels. For example, if you assign a user the Editor role at the account level, then that user also has the Editor role at the property and view levels (and you cannot revoke those permissions at the property or view level). Conversely, you can assign a user the Editor role at the view level, but assign no permissions at either the property or account level. Learn more about access.

Create user groups

You can create user groups with permissions for your Analytics account.

After you create a group, it appears in the users lists for your Analytics account and for your organization.

The group has permissions for the level in the Analytics hierarchy where you create the group. For example, if you create the group at the view level, then it has permissions only for that view. If you create it at the property level, then it has permissions for that property and all its views. If you create it at the account level, then it has permissions for all properties and views. See Edit user groups below for information about adding permissions to other levels of the Analytics hierarchy.
