음성을 통한 계정 생성 지원
음성을 통한 사용자 계정 생성을 허용하면 어시스턴트에서 사용자에게 다음과 같이 하려고 합니다.
- Google 계정 정보를 사용하여 시스템에서 새 계정을 만듭니다.
- 다른 계정이 있는 경우 다른 계정으로 인증 시스템에 로그인하세요. 계정에 연결할 수 없습니다.
이러한 문제를 최소화하려면 음성을 통한 계정 생성을 허용하는 것이 좋습니다. 계정 생성 흐름의 마찰이 있습니다 사용자는 음성 흐름에서 나가기만 하면 됨 (Google 계정이 아닌 기존 계정을 사용하여 로그인하려는 경우).
음성을 통한 계정 생성 허용 안함
음성을 통한 사용자 계정 생성을 허용하지 않은 경우 어시스턴트는 사용자 인증을 위해 제공한 웹사이트가 포함됩니다. 상호 작용이 발생하는 경우 화면이 없는 기기에서는 어시스턴트가 사용자를 휴대전화로 안내합니다. 계정 연결 절차를 계속 진행합니다.
다음과 같은 경우 생성을 허용하지 않는 것이 좋습니다.
Google 이외의 계정이 있는 사용자가 해당 사용자가 계정의 기존 사용자 계정에 연결하도록 하려는 인증 시스템을 사용할 것입니다. 예를 들어 포인트 멤버십을 제공하는 경우 사용자가 포인트를 잃어버리지 않도록 계정을 만들 수 있습니다.

OAuth 및 Google 로그인 계정 연결 구현
계정은 업계 표준 OAuth 2.0 흐름으로 연결됩니다. Actions on Google은 암시적 코드 및 승인 코드 흐름을 지원합니다.
In the implicit code flow, Google opens your authorization endpoint in the user's browser. After successful sign in, you return a long-lived access token to Google. This access token is now included in every request sent from the Assistant to your Action.
In the authorization code flow, you need two endpoints:
- The authorization endpoint, which is responsible for presenting the sign-in UI to your users that aren't already signed in and recording consent to the requested access in the form of a short-lived authorization code.
- The token exchange endpoint, which is responsible for two types of exchanges:
- Exchanges an authorization code for a long-lived refresh token and a short-lived access token. This exchange happens when the user goes through the account linking flow.
- Exchanges a long-lived refresh token for a short-lived access token. This exchange happens when Google needs a new access token because the one it had expired.
Although the implicit code flow is simpler to implement, Google recommends that access tokens issued using the implicit flow never expire, because using token expiration with the implicit flow forces the user to link their account again. If you need token expiration for security reasons, you should strongly consider using the auth code flow instead.

OAuth 서버 구현
To support the OAuth 2.0 implicit flow, your service makes an authorization endpoint available by HTTPS. This endpoint is responsible for authenticating and obtaining consent from users for data access. The authorization endpoint presents a sign-in UI to your users that aren't already signed in and records consent to the requested access.
When your Action needs to call one of your service's authorized APIs, Google uses this endpoint to get permission from your users to call these APIs on their behalf.
A typical OAuth 2.0 implicit flow session initiated by Google has the following flow:
- Google opens your authorization endpoint in the user's browser. The user signs in if not signed in already, and grants Google permission to access their data with your API if they haven't already granted permission.
- Your service creates an access token and returns it to Google by redirecting the user's browser back to Google with the access token attached to the request.
- Google calls your service's APIs, and attaches the access token with each request. Your service verifies that the access token grants Google authorization to access the API and then completes the API call.
Handle authorization requests
When your Action needs to perform account linking via an OAuth2 implicit flow, Google sends the user to your authorization endpoint with a request that includes the following parameters:
Authorization endpoint parameters | |
---|---|
client_id |
The client ID you assigned to Google. |
redirect_uri |
The URL to which you send the response to this request. |
state |
A bookkeeping value that is passed back to Google unchanged in the redirect URI. |
response_type |
The type of value to return in the response. For the OAuth 2.0 implicit
flow, the response type is always token . |
For example, if your authorization endpoint is available at https://myservice.example.com/auth
,
a request might look like:
GET https://myservice.example.com/auth?client_id=GOOGLE_CLIENT_ID&redirect_uri=REDIRECT_URI&state=STATE_STRING&response_type=token
For your authorization endpoint to handle sign-in requests, do the following steps:
Verify the
client_id
andredirect_uri
values to prevent granting access to unintended or misconfigured client apps:- Confirm that the
client_id
matches the client ID you assigned to Google. - Confirm that the URL specified by the
redirect_uri
parameter has the following form: YOUR_PROJECT_ID is the ID found on the Project settings page of the Actions Console.https://oauth-redirect.googleusercontent.com/r/YOUR_PROJECT_ID
- Confirm that the
Check if the user is signed in to your service. If the user isn't signed in, complete your service's sign-in or sign-up flow.
Generate an access token that Google will use to access your API. The access token can be any string value, but it must uniquely represent the user and the client the token is for and must not be guessable.
Send an HTTP response that redirects the user's browser to the URL specified by the
redirect_uri
parameter. Include all of the following parameters in the URL fragment:access_token
: the access token you just generatedtoken_type
: the stringbearer
state
: the unmodified state value from the original request The following is an example of the resulting URL:https://oauth-redirect.googleusercontent.com/r/YOUR_PROJECT_ID#access_token=ACCESS_TOKEN&token_type=bearer&state=STATE_STRING
Google's OAuth 2.0 redirect handler will receive the access token and confirm
that the state
value hasn't changed. After Google has obtained an
access token for your service, Google will attach the token to subsequent calls
to your Action as part of the AppRequest.
Handle automatic linking
After the user gives your Action consent to access their Google profile, Google sends a request that contains a signed assertion of the Google user's identity. The assertion contains information that includes the user's Google Account ID, name, and email address. The token exchange endpoint configured for your project handles that request.
If the corresponding Google account is already present in your authentication system,
your token exchange endpoint returns a token for the user. If the Google account doesn't
match an existing user, your token exchange endpoint returns a user_not_found
error.
The request has the following form:
POST /token HTTP/1.1 Host: oauth2.example.com Content-Type: application/x-www-form-urlencoded grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer&intent=get&assertion=JWT&consent_code=CONSENT_CODE&scope=SCOPES
Your token exchange endpoint must be able to handle the following parameters:
Token endpoint parameters | |
---|---|
grant_type |
The type of token being exchanged. For these requests, this
parameter has the value urn:ietf:params:oauth:grant-type:jwt-bearer . |
intent |
For these requests, the value of this parameter is `get`. |
assertion |
A JSON Web Token (JWT) that provides a signed assertion of the Google user's identity. The JWT contains information that includes the user's Google Account ID, name, and email address. |
consent_code |
Optional: When present, a one-time code that indicates that the user has granted consent for your Action to access the specified scopes. |
scope |
Optional: Any scopes you configured Google to request from users. |
When your token exchange endpoint receives the linking request, it should do the following:
Validate and decode the JWT assertion
You can validate and decode the JWT assertion by using a JWT-decoding library for your language. Use Google's public keys (available in JWK or PEM format) to verify the token's signature.
When decoded, the JWT assertion looks like the following example:
{ "sub": 1234567890, // The unique ID of the user's Google Account "iss": "https://accounts.google.com", // The assertion's issuer "aud": "123-abc.apps.googleusercontent.com", // Your server's client ID "iat": 233366400, // Unix timestamp of the assertion's creation time "exp": 233370000, // Unix timestamp of the assertion's expiration time "name": "Jan Jansen", "given_name": "Jan", "family_name": "Jansen", "email": "jan@gmail.com", // If present, the user's email address "locale": "en_US" }
In addition to verifying the token's signature, verify that the assertion's issuer
(iss
field) is https://accounts.google.com
and that the audience (aud
field)
is the client ID assigned to your Action.
Check if the Google account is already present in your authentication system
Check whether either of the following conditions are true:
- The Google Account ID, found in the assertion's
sub
field, is in your user database. - The email address in the assertion matches a user in your user database.
If either condition is true, the user has already signed up and you can issue an access token.
If neither the Google Account ID nor the email address specified in the assertion
matches a user in your database, the user hasn't signed up yet. In this case, your
token exchange endpoint should reply with a HTTP 401 error, that specifies error=user_not_found
,
as in the following example:
HTTP/1.1 401 Unauthorized Content-Type: application/json;charset=UTF-8 { "error":"user_not_found", }
user_not_found
error, Google
calls your token exchange endpoint with the value of the intent
parameter
set to create and sending an ID token that contains the user's profile information
with the request.
Handle account creation via Google Sign-In
When a user needs to create an account on your service, Google makes a
request to your token exchange endpoint that specifies
intent=create
, as in the following example:
POST /token HTTP/1.1 Host: oauth2.example.com Content-Type: application/x-www-form-urlencoded response_type=token&grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer&scope=SCOPES&intent=create&consent_code=CONSENT_CODE&assertion=JWT[&NEW_ACCOUNT_INFO]
The assertion
parameter contains A JSON Web Token (JWT) that provides
a signed assertion of the Google user's identity. The JWT contains information
that includes the user's Google Account ID, name, and email address, which you can use
to create a new account on your service.
To respond to account creation requests, your token exchange endpoint must do the following:
Validate and decode the JWT assertion
You can validate and decode the JWT assertion by using a JWT-decoding library for your language. Use Google's public keys (available in JWK or PEM format) to verify the token's signature.
When decoded, the JWT assertion looks like the following example:
{ "sub": 1234567890, // The unique ID of the user's Google Account "iss": "https://accounts.google.com", // The assertion's issuer "aud": "123-abc.apps.googleusercontent.com", // Your server's client ID "iat": 233366400, // Unix timestamp of the assertion's creation time "exp": 233370000, // Unix timestamp of the assertion's expiration time "name": "Jan Jansen", "given_name": "Jan", "family_name": "Jansen", "email": "jan@gmail.com", // If present, the user's email address "locale": "en_US" }
In addition to verifying the token's signature, verify that the assertion's issuer
(iss
field) is https://accounts.google.com
and that the audience (aud
field)
is the client ID assigned to your Action.
Validate user information and create new account
Check whether either of the following conditions are true:
- The Google Account ID, found in the assertion's
sub
field, is in your user database. - The email address in the assertion matches a user in your user database.
If either condition is true, prompt the user to link their existing account with
their Google Account by responding to the request with an HTTP 401 error, specifying
error=linking_error
and the user's email address as the login_hint
, as in the
following example:
HTTP/1.1 401 Unauthorized Content-Type: application/json;charset=UTF-8 { "error":"linking_error", "login_hint":"foo@bar.com" }
If neither condition is true, create a new user account using the information provided in the JWT. New accounts do not typically have a password set. It is recommended that you add Google Sign In to other platforms to enable users to log in via Google across the surfaces of your application. Alternatively, you can email the user a link that starts your password recovery flow to allow the user to set a password for signing in on other platforms.
When the creation is completed, issue an access token and return the values in a JSON object in the body of your HTTPS response, like in the following example:
{ "token_type": "Bearer", "access_token": "ACCESS_TOKEN", "expires_in": SECONDS_TO_EXPIRATION }
