CommCare mobile workers Mobile Workers are the accounts people will use to log in on their phones and submit data to your project space. CommCare mobile workers can also log in to CommCareHQ, but they will can only be able to see the same information they have access to on their phone phones. (Your application must be Web Apps-enabled for this to work - see . See Web Apps for more information).

To manage mobile workers, click on "Users " in the top navigation bar. You will automatically be taken to the Mobile Workers section.

    , your new mobile worker

    has been

    is created; it is NOT necessary to add any additional information unless you choose to. 
    The username and password you set here will be what the CommCare mobile worker uses to log into the phone application.


    Note: All usernames must be in the Roman alphabet, and once created, the username can NOT be changed! (


    For more information on usernames, see choosing a username section below)

    1. If you have Custom User Data or Locations that are required, you will also have to add that information at this time.

titleChoosing a Username

We recommend you consider carefully what types of usernames you want to use. Here are some different approaches:

  • First name  - this is simple for people to remember, but if you have multiple users with the same name, you will have to come up with a strategy, such as serials (laxmi, laxmi2, laxmi3) or use of a second initial.
  • Phone number  - is a unique number and easy for most people to remember.
  • First.last name  - is longer and more complex but more likely to be unique for each user.
  • Sector/Coverage area name  - this has the advantage that if there is lots of turnover, multiple people can use the same username; however, you will not be able to tell which individual person has submitted the data when analyzing later.

Best practices for Mobile Worker Usernames:  

  • Design the username so that it is meaningful for the Mobile Worker entering data. 
  • If you are tracking the performance of each Mobile Worker individually, we recommend each Mobile Worker should have their own username even if they are sharing a device. CommCare HQ will give you reports on the performance/productivity of your Mobile Workers. If you have multiple Mobile Workers sharing a username, then the performance reports on CommCareHQ will reflect team performance and not necessarily individual performance.
  • You may not have duplicate usernames. According to your format, if there is a duplicate username, then you should add some distinction. For example, if there are two Kherunishas in this mobile project, assign one with the username “kherunisha” and the other “kherunisha2.”
  • You may use periods ‘.’ in the username.
  • You may not use ‘_’ in the username.
  • You may not use special characters apart from periods '.' as mentioned above.

  • You may use numbers and/or letters in your username.
  • All characters should be lowercase in the username.
  • All usernames should be in English (Roman Alphabet).

Best practices for Mobile Worker Passwords:      

  • Avoid setting the Mobile Worker’s passwords the same as the Admin password. Technical staff associated with your project will have access to the Admin password and may log in in Admin mode for installation and troubleshooting. The default Admin password is 234. (Note that the Admin password is configurable).
  • We recommend keeping passwords simple, so Mobile Workers do not forget the password and thus face a barrier in using the application.


You can change the First/Last names, E-mail, default language, and role. In general, it is only useful to add the First and Last names, as you can see these names in reports, in addition to the username.


It is possible to add additional information about your users with Custom User Data, an advanced feature.  Additional Additional user information you may want to consider are is listed below:

  • Mobile Phone IMEI number and Device Model for an inventory of the devices handed out to Mobile Workers
  • Mobile Worker demographic information such as education, age, and literacy for training purposes.


Phone Number

Make sure to add the international country international country code , without any symbols (do NOT add + or 00). After adding a new number, you will be prompted to verify it. This will send you an SMS to which you must reply.


On CommCare HQ, you can change or reset the password for any mobile worker by navigating to the "Password " tab and specifying the new password. However, it is important to note that the user login information (username and password) is stored locally on the phone. So, when you change in CommCare HQ, the username and password aren't communicated downward to the phone until the phone "synchronizes with server".

On CommCare, ''Sync with server" is an option on the home page of the phone. So, the CommCare mobile worker must synchronize with the server for the username and/or password change to reflect on the phone side. 


  1. Navigate to the Mobile Workers page on your CommCareHQ project space, as above.
    CommCareHQ > Users > Mobile Workers (the page to manage Mobile Workers will show by default
  2. Click on "Bulk Upload".

  3. Follow the three steps indicated to download the user.xlsx file. This contains all of your current user data. This is the same data accessible by clicking the "Download Mobile Workers " button shown above:
    1. The first tab contains a row for each mobile worker with the following data:
      1. Basic columns: username, password, name, phone number, email, user_id, language, role, is_active
      2. Read-only columns: IMEI, date registered, date of last sync, date of last form submission
      3. Any custom user data fields configured for your project
      4. User location code, if your project uses organizations
    2. The second tab contains a row for each group, with its id, name, and whether it is a case sharing group and/or reporting group.
  4. Click the "Upload mobile workers" button  button to upload the completed file. 

titleBulk Upload Tips and Advanced Info

Sample bulk users excel template


***user_id will be blank if this is a new mobile worker


  • Your first column in excel should say "username", with no spaces. Note that username is required.
  • Your second column in excel should say "language". Use the language codes in CommCare, (ex. English = en, French = fra) 
  • Name and phone number are optional (but recommended!) fields.
  • For any new users, the password is required.  For existing users that are in the download, the password will be listed as a *********.  When uploading the file again, the password for these existing users will not be changed.  
  • Remember to add the international country code to the phone numbers. 
  • Add a space between the first and last name of your CommCare user. Do not need to use periods or other punctuation to separate.

  • Any additional data can be stored by user by adding columns with 'data: xxxx' in the first row of the column.  For instance, village, block, etc can be added, and will be stored. For more information, see Custom User Data
  • Mobile workers can be assigned a phone number or multiple phone numbers during bulk upload. To do this, add one or more columns with ‘phone-number xxxx’ in the first row of the column, where ‘xxxx’ is a sequential number (not the phone number). For example, if a user has more than one phone number, this can be sequential numbering, such as “phone-number 1”, then “phone-number 2” and so on. For a user with only one phone number in the “phone-number 1” column, that phone number will automatically be marked as ‘primary’ in CommCare. For a user with several phone numbers, the phone number in the “phone-number 1” column will be marked as ‘primary.’ Inversely, if at least one mobile worker has more than one phone number in CommCare, downloading the user.xlsx file as explained above will generate a file that contains N “phone-number” columns, N being the maximum number of phone numbers that a mobile worker has.

  • A web user is able to update or delete an existing phone number via bulk upload. To update an existing phone number, the web user needs to edit the phone number in the appropriate cell, save the excel file and upload it. To delete a phone number, the web user simply needs to delete the number in the appropriate cell (leave the cell blank), save the excel file and upload it.
  • If you neither want to delete nor update the phone numbers for any mobile worker, you can simply remove any "phone-number" columns from the upload. This will cause the phone numbers associated with the mobile workers to remain unchanged.

  • Users can be pre-assigned to groups during bulk upload.  To do this, any column needs to have the syntax 'group (xxxx)' in the first row of the column. (Note that the 'xxxx' is any identifier, and is not the group name. To keep things simple, this can be sequential numbering, such as "group 1" then "group 2" and so on.)  Any user can be a member of multiple groups of different types by simply adding columns with the correct group syntax.  For groups, make sure you define the group on the 'groups' tab of the spreadsheet , and indicate which type of group it is. For more detail see see Mobile Worker Groups.
  • For groups, make sure you define the group on the 'groups' tab of the spreadsheet , and indicate which type of group it is:  There There are two types of groups:  11) Reporting groups - these groups users to view by group in the Filters on the Reporting section of HQ.  For example, you can group all mobile users within one Village or SubCenter. 2) Case sharing groups - these groups allow cases to be shared by different users.  For instance, if two mobile users were sharing the same catchment area, case information could be shared between these two users.


You can use the search box to find specific mobile workers. Type in any word to search for that term across all columns , or use the syntax below to search in a specific column. 


You can unclutter your reports in two different ways. You may either deactivate (formerly "Archive")a user, removing them from the limelight while keeping their data around in the export; , or you can can delete a user removing all their data permanently. 


This will remove users from the report dashboards while keeping their data in the export. Deactivate a user by clicking the "deactivate " button on the main Mobile Workers page. Deactivated users will no longer be able to log into a new phone for the first time. (Note that you can deactivate a large number of mobile workers by following the "Bulk deactivation" process below).

If a deactivated user submits a form, the following will occur:

  • If your app is using secure submissions, deactivated users' new submissions will be rejected and will stay on the phone
  • If your app is not using secure submissions, then it behaves like any other submission, and all case transactions are processed.
  • Note: Secure Submissions are enabled for your project by default. For more information, please see this help page.

Activate Deactivated Users


Note: Deactivate mobile worker was formerly called Archive mobile worker. When looking for information in the Commcare User's Forum relevant , relevant discussions may sometimes be described as "archive".

Bulk Deactivation of Mobile workers


  1. Go to the User page, click "Bulk upload", click on "download Mobile workers", get to the downloaded excel spreadsheet.
  2. For the workers, you want to deactivate, go to the column "is active" and change the value to false. 
  3. Save the Excel file. Re-upload the excel file.


titleDeleting Mobile Users: Are you sure you want to do that?

You may notice that we make it a bit difficult to delete mobile workers. This is because if you delete a mobile worker, you will also be deleting all data that that the worker ever submitted. It is not possible to ever get that information back if you delete a mobile worker. We very very strongly recommend deactivating mobile workers if there is any chance you will ever want to see any of the data submitted by that worker.

Note: once you delete a mobile worker, you can never create a new worker with that username.

This will remove all of the user’s data permanently. Delete a user by clicking on a user's name and navigating to "Permanent Actions". Then press click the "Delete Mobile Worker" button and follow the directions.


  1. Let's say that while you were testing your app, you created a mobile worker called "test". You might play around with the user and submit a few forms, but none of that data is real, so it shouldn't interfere with the real data, and you will never need to use this data again. In this case, you may want to delete the user and all their data.
  2. Let's say instead that you have a mobile worker who has submitted some data but who has taken a leave of absence. You do not want them showing up in your reports day-to-day, but you want to keep their data around. Then you would deactivate them.
