TOTP (Google Authenticator)

You can enable Time-Based One-Time Password authentication in the Ory Identity Service (Kratos) to allow users to perform 2FA with TOTP apps such as the Google Authenticator.

When enabled, users can pair a TOTP app with their account:

note

The example screenshot is captured using the Ory Managed UI.

When attempting to perform actions secured with 2FA, users get a TOTP code with the application identifier:

In this example, the user identifier (email - alice@example.com) is used. To learn how to enable this behavior, read this section.

Configuration

Follow these steps to enable Time-Based One-Time Password (TOTP) as the second authentication factor:

Ory Cloud Console

1. Sign in to the Ory Cloud Console and go to Two-Factor Authentication.
2. In the TOTP Authenticator App section, use the switch to enable TOTP.
3. Define the name of the requesting party in the Display Name. The users sees this name in the TOTP application when getting a one-time password.
4. Click Save to finish.

Ory CLI

1. Get the Identity Service configuration from your project and save it to a file:

## List all available projects
ory list projects

## Get config
ory get identity-config <project-id> --format yaml > identity-config.yaml

2. Find totp in selfservice/methods, set enabled to true, and define the issuer:

identity-config.yaml

selfservice:
  methods:
    totp:
      config:
        # The "issuer" is the name in the TOTP application users see when getting a one-time password.
        issuer: ExampleIssuer.com
      enabled: true

3. Update the Ory Cloud Identity Service configuration using the file you worked with:

ory update identity-config <project-id> --file identity-config.yaml

Self-Hosted Instances

When working with self-hosted instances of the Ory Identity Service (Kratos), add the totp method to selfservice/methods in the configuration file:

kratos.config.yml

selfservice:
  methods:
    totp:
      config:
        # The "issuer" is the name in the TOTP application users see when getting a one-time password.
        issuer: ExampleIssuerForSelfHosted.com
      enabled: true

Distinguishing Identities Requesting TOTP

To help users distinguish which identity requests for the TOTP code, add a totp object to the trait which represents the TOTP account name.

In this example, the user's email address is the identifier:

note

This configuration is the default for all Ory Cloud projects.

sample identity schema

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "properties": {
    "traits": {
      "type": "object",
      "properties": {
        "email": {
          "type": "string",
          "format": "email",
          "title": "Your E-Mail",
          "minLength": 3,
          "ory.sh/kratos": {
            "credentials": {
              // ...
              "totp": {
                "account_name": true
              }
            }
            // ...
          }
        }
        // ...
      }
      // ...
    }
  }
}

Writing E2E Tests

When writing end-to-end (E2E) tests for TOTP implementation in your app, you can reference the Cypress tests used in Ory Identity Service (Kratos).

Identity Credentials

When the user enables TOTP, Ory adds the following entries to the credentials object of the associated Identity:

credentials:
  password:
    id: totp
    identifiers:
      - 802471b9-06f5-49d4-a88d-5e7d6bcfed22
    config:
      # This is the TOTP URL which contains the pre-shared key and some additional meta-information.
      totp_url: otpauth://totp/Example:alice@example.org?secret=JBSWY3DPEHPK3PXP&issuer=Example
