In some cases a user has created a trial account in QuickBase and has also been given a user profile that has access to applications belonging to a regular Billing Account (paid subscription).

If QuickBase displays a message telling you that you can't change your password,

First, confirm that the email address connected with your user account is the one you're checking for your password email message. QuickBase sends the password message to the same email address you used to create your user account.

A Billing Account Administrator determines which users are able to create applications. You control this ability using the Create Applications checkbox next to each user's name under the 'Permissions' tab. (Read https://www.quickbase.com/help/controlling_db_creation.html for details.)

Follow these steps to clean up your user accounts.

Note: For security reasons, you cannot browse existing groups unless you are a member of the group. To join a group, you must be added by an administrator of that group.

The best way to create a user hierarchy in QuickBase is to have a table of users. The key field in this table should be a user field. For each level of the management hiearchy you add another user field to this table. So for example the first user field in this table would be called Sales Rep. If each sales rep has a manager then you would create another user field called Manager.

During the import process, if you import your resources, or contacts, by name into a user field (such as Assigned To), QuickBase may not recognize the names as users. Read more about user fields here:
