ProfileUserInfo
should be returned. Defaults toSYNC

ProfileUserInfo
Properties
-
email
string
An email address for the user account signed into the current profile. Empty if the user is not signed in or the
identity.email
manifest permission is not specified. -
id
string
A unique identifier for the account. This ID will not change for the lifetime of the account. Empty if the user is not signed in or (in M41+) the
identity.email

TokenDetails
Properties
-
account
AccountInfo optional
The account ID whose token should be returned. If not specified, the function will use an account from the Chrome profile: the Sync account if there is one, or otherwise the first Google web account.
-
enableGranularPermissions
boolean optional
Chrome 87+The
enableGranularPermissions
flag allows extensions to opt-in early to the granular permissions consent screen, in which requested permissions are granted or denied individually. -
interactive
boolean optional
Fetching a token may require the user to sign-in to Chrome, or approve the application's requested scopes. If the interactive flag is
true
,getAuthToken
will prompt the user as necessary. When the flag isfalse
or omitted,getAuthToken
will return failure any time a prompt would be required. -
scopes
string[] optional
A list of OAuth2 scopes to request.
When the
scopes
field is present, it overrides the list of scopes specified in manifest.json.
WebAuthFlowDetails
Properties
-
abortOnLoadForNonInteractive
boolean optional
Chrome 113+Whether to terminate
launchWebAuthFlow
for non-interactive requests after the page loads. This parameter does not affect interactive flows.When set to
true
(default) the flow will terminate immediately after the page loads. When set tofalse
, the flow will only terminate after thetimeoutMsForNonInteractive
passes. This is useful for identity providers that use JavaScript to perform redirections after the page loads. -
interactive
boolean optional
Whether to launch auth flow in interactive mode.
Since some auth flows may immediately redirect to a result URL,
launchWebAuthFlow
hides its web view until the first navigation either redirects to the final URL, or finishes loading a page meant to be displayed.If the
interactive
flag istrue
, the window will be displayed when a page load completes. If the flag isfalse
or omitted,launchWebAuthFlow
will return with an error if the initial navigation does not complete the flow.For flows that use JavaScript for redirection,
abortOnLoadForNonInteractive
can be set tofalse
in combination with settingtimeoutMsForNonInteractive
to give the page a chance to perform any redirects. -
timeoutMsForNonInteractive
number optional
Chrome 113+The maximum amount of time, in miliseconds,
launchWebAuthFlow
is allowed to run in non-interactive mode in total. Only has an effect ifinteractive
isfalse
. -
url
string
The URL that initiates the auth flow.
Methods
clearAllCachedAuthTokens()
chrome.identity.clearAllCachedAuthTokens(
callback?: function,
)
Resets the state of the Identity API:
- Removes all OAuth2 access tokens from the token cache
- Removes user's account preferences
- De-authorizes the user from all auth flows
Parameters
-
callback
function optional
The
callback
parameter looks like:() => void
Returns
-
Promise<void>
Chrome 106+Promises are supported in Manifest V3 and later, but callbacks are provided for backward compatibility. You cannot use both on the same function call. The promise resolves with the same type that is passed to the callback.
getAccounts()
chrome.identity.getAccounts(
callback?: function,
)
Retrieves a list of AccountInfo objects describing the accounts present on the profile.
getAccounts
is only supported on dev channel.
Parameters
-
callback
function optional
The
callback
parameter looks like:(accounts: AccountInfo[]) => void
-
accounts
-
Returns
-
Promise<AccountInfo[]>
Promises are supported in Manifest V3 and later, but callbacks are provided for backward compatibility. You cannot use both on the same function call. The promise resolves with the same type that is passed to the callback.
getAuthToken()
chrome.identity.getAuthToken(
details?: TokenDetails,
callback?: function,
)
Gets an OAuth2 access token using the client ID and scopes specified in the oauth2
section of manifest.json.
The Identity API caches access tokens in memory, so it's ok to call getAuthToken
non-interactively any time a token is required. The token cache automatically handles expiration.
For a good user experience it is important interactive token requests are initiated by UI in your app explaining what the authorization is for. Failing to do this will cause your users to get authorization requests, or Chrome sign in screens if they are not signed in, with with no context. In particular, do not use getAuthToken
interactively when your app is first launched.
Note: When called with a callback, instead of returning an object this function will return the two properties as separate arguments passed to the callback.
Parameters
-
details
TokenDetails optional
Token options.
-
callback
function optional
The
callback
parameter looks like:(result: GetAuthTokenResult) => void
-
resultChrome 105+
-
Returns
-
Promise<GetAuthTokenResult>
Chrome 105+Promises are supported in Manifest V3 and later, but callbacks are provided for backward compatibility. You cannot use both on the same function call. The promise resolves with the same type that is passed to the callback.
getProfileUserInfo()
chrome.identity.getProfileUserInfo(
details?: ProfileDetails,
callback?: function,
)
Retrieves email address and obfuscated gaia id of the user signed into a profile.
Requires the identity.email
manifest permission. Otherwise, returns an empty result.
This API is different from identity.getAccounts in two ways. The information returned is available offline, and it only applies to the primary account for the profile.
Parameters
-
details
ProfileDetails optional
Chrome 84+Profile options.
-
callback
function optional
The
callback
parameter looks like:(userInfo: ProfileUserInfo) => void
-
userInfo
-
Returns
-
Promise<ProfileUserInfo>
Chrome 106+Promises are supported in Manifest V3 and later, but callbacks are provided for backward compatibility. You cannot use both on the same function call. The promise resolves with the same type that is passed to the callback.
getRedirectURL()
chrome.identity.getRedirectURL(
path?: string,
)
Generates a redirect URL to be used in launchWebAuthFlow
.
The generated URLs match the pattern https://<app-id>.chromiumapp.org/*
.
Parameters
-
path
string optional
The path appended to the end of the generated URL.
Returns
-
string
launchWebAuthFlow()
chrome.identity.launchWebAuthFlow(
details: WebAuthFlowDetails,
callback?: function,
)
Starts an auth flow at the specified URL.
This method enables auth flows with non-Google identity providers by launching a web view and navigating it to the first URL in the provider's auth flow. When the provider redirects to a URL matching the pattern https://<app-id>.chromiumapp.org/*
, the window will close, and the final redirect URL will be passed to the callback
function.
For a good user experience it is important interactive auth flows are initiated by UI in your app explaining what the authorization is for. Failing to do this will cause your users to get authorization requests with no context. In particular, do not launch an interactive auth flow when your app is first launched.
Parameters
-
details
WebAuth flow options.
-
callback
function optional
The
callback
parameter looks like:(responseUrl?: string) => void
-
responseUrl
string optional
-
Returns
-
Promise<string | undefined>
Chrome 106+Promises are supported in Manifest V3 and later, but callbacks are provided for backward compatibility. You cannot use both on the same function call. The promise resolves with the same type that is passed to the callback.
removeCachedAuthToken()
chrome.identity.removeCachedAuthToken(
details: InvalidTokenDetails,
callback?: function,
)
Removes an OAuth2 access token from the Identity API's token cache.
If an access token is discovered to be invalid, it should be passed to removeCachedAuthToken to remove it from the cache. The app may then retrieve a fresh token with getAuthToken
.

callback
parameter looks like:() => void
