Switch to Kinde for user authentication

Link to this section

If you are currently using a different authentication tool to manage users, you can switch to Kinde pretty quickly. The method described here involves importing user details from CSV files into Kinde.

Before you begin, get a Kinde account and set it up.

Step 1: Prepare user data

Link to this section

You can export user details and data fairly easily from most auth providers. However some companies, like Auth0, require you to separately request password details for users and this can take a little while. If you’re using your own auth system, prepare data as described below.

User data can only be imported from a CSV file. Depending on what you currently use for auth, you will need to export or prepare data in a CSV file. Note that if you use Auth0, user data comes in a CSV file and passwords are provided in a JSON file.

Kinde can import files up to 1MB, which is around 10,000 records.

Export data from Auth0

When you export user data from Auth0, export all the default fields and add these additional ones to the export:


User data from MS Azure AD

Link to this section

We recommend you set up the Azure AD connection in Kinde before you import your users.

When you import user details from MS Azure AD they must include an Azure ID so Kinde can match them to the connection you set up.

Export data from other systems or your own system

Link to this section

When exporting data from another auth system or your own system, the CSV file you export may need to be edited to ensure data is formatted in rows with some of these column headings.

Recommended minimum columns

  • email - this is a required field to import to Kinde
  • first_name
  • last_name

Optional columns if applicable

  • id - unique to the auth provider and helps us match records as they are imported.
  • email_verified - account verification status: TRUE or FALSE
  • hashed_password - encrypted using an algorithm such as bcrypt, crypt or md5
  • hashing_method - tells us which algorithm was used to encrypt the password
  • salt - extra characters added to passwords to make them stronger
  • salt_position - position of salt in password string. Prefix (before) or suffix (after)
  • external_organization_id - the ID of the organizations you want the user to be imported into (if you have more organizations than the default one)
  • Note that only the email field is mandatory, but the more data that you bring in, the easier we can set up your users in Kinde.

Check for errors

Before importing, check the CSV for missing information or duplication. Kinde will check for some errors during import, and report these back to you.

If you want your users to have an uninterrupted sign in experience as you change providers, you will need to bring their password data from your auth provider. Passwords are usually ‘hashed’ or encrypted so they cannot be read and they may be ‘salted’ as well (see above).

If you decide not to import passwords, however, it’s not a big deal. Users will be prompted to reset their password or sign in using whatever authentication methods you have chosen to set up in Kinde.

Step 2 (optional): Set up organizations

Link to this section

If you require multi-tenanting for your users, for instance if you manage a B2B business, or require separated user groups, then you need to set up organizations in Kinde first.

When you import your user records, you will need to include an external_organization_id column in the CSV, that matches the organization name in Kinde. To add a user to multiple organizations, separate the IDs with a comma.

See Add and manage organizations.

Step 3: Set up user authentication

Link to this section

Before you import your users, you’ll want to set up the authentication method they can use when signing up or signing in. The following options are available:

  • Passwords - switch this option on before importing user passwords
  • Passwordless - users will be sent a one-time code to sign in
  • Social sign-on (SSO) - users can sign up and in using Google, Apple, etc.

For information, see Select authentication methods.

Step 4: Import users

Link to this section

Once you have your user details, you’re ready to import them.

  1. In Kinde, go to Users, then select Import users.
  2. Select the Import users tab and then select the option for your situation:
    • Import from Auth0
    • Import from a CSV
  3. Follow the on-screen prompts to upload the user data.
  4. If there are any errors with the import, you will be able to view them afterwards.
  5. Most import errors can be fixed by editing the CSV file and then re-importing into Kinde. Any records that have already been imported and have not been edited, will be ignored.

Communication to users

Link to this section

Kinde does not send any notifications or invitations to users when they are newly added to Kinde. The idea is that your users have a seamless experience that feels (almost) like it always has.

If you’ve made changes to their sign in experience — for example adding multi-factor authentication — then consider contacting your users to let them know their sign in experience will be changed.

What users might notice

Link to this section

Importing all your exisiting users and passwords should mean that your users won’t notice anything when they next sign in. This is the optimal experience. However:

  • If a user changes their password after the user export and while the migration is in progress, they will be prompted to reset their password on the next sign in.
  • If you have set up a new authentication method as part of the user migration (for instance, going passwordless) your users will be prompted to use the new method on sign in.
