overview stay organized with collections save and categorize content based on your preferences page summary outlined_flag account linking securely connects a user s google account to their account on your platform using the oauth 2 0 protocol allowing google apps and services to access data and services you host with user consent google account linking can be used for various purposes including sharing user data with google apps enabling features like google tv and smart home integration creating custom google assistant experiences and streamlining account creation during sign up there are three primary oauth based flows for google account linking web oauth redirects to your website app flip switches to your mobile app and streamlined linking completes the process within the google surface implementing the web oauth flow is required as a fallback for all account linking integrations google account linking utilizes standard oauth 2 0 token types authorization code access token and refresh token for secure communication and data sharing between systems choose your integration path select the path that best suits your needs path best for learn more universal commerce protocol ucp merchants and retailers ucp docs standard account linking smart home tv and youtube docs note these integration paths are complementary if you are implementing ucp we recommend reviewing both the ucp identity linking guide for product specific requirements and this documentation for core oauth implementation details account linking enables google account holders to quickly seamlessly and safely connect to your services you may choose to implement google account linking to share a user s data from your platform with google apps and services the secure oauth 2 0 protocol lets you safely link a user s google account with their account on your platform thereby granting google applications and devices access to your services users can link or unlink their accounts and optionally create a new account on your platform with google account linking use cases some of the reasons to implement google account linking are share a user s data from your platform with google apps and services integrate with google shopping and ai surfaces search gemini using the universal commerce protocol ucp play your video and movie content using google tv manage and control google smart home connected devices using the google home app and google assistant hey google turn on the lights create user customized google assistant experiences and functionality with conversational actions hey google order my usual from starbucks enable users to earn rewards by viewing eligible live streams on youtube after linking their google account to a rewards partner account pre populate new accounts during sign up with consensually shared data from a google account profile capabilities requirements the following matrix defines the support and recommendations for each linking flow linking flow standard features ucp features app flip recommended recommended streamlined linking recommended recommended oauth linking required fallback required fallback oauth 2 1 recommended recommended agentic development mcp ucp large language models llms and ai agents require robust authentication to access user data google account linking supports these emerging paradigms model context protocol mcp gal acts as the security handshake agents use oauth 2 1 tokens to securely query your mcp server tools universal commerce protocol ucp enables shopping agents to access user profiles and payment vectors securely improve user privacy by defining custom scopes to share only necessary data increase user trust by clearly defining how their data is used access to data and services hosted on your platform can be revoked by unlinking accounts implementing an optional token revocation endpoint lets you stay in sync with google initiated events while cross account protection risc lets you notify google of any unlinking events that take place on your platform note most of the oauth 2 0 documentation for the google identity platform covers how you can sign in your users with their google accounts and get authorization to call google apis on their behalf google account linking covers the reverse case of allowing the user of a google service to authenticate with your platform and call your service s apis if you want to use oauth 2 0 to access google apis see the oauth 2 0 client documentation account linking flows there are 3 google account linking flows all of which are oauth based and require you to manage or control oauth 2 0 compliant authorization and token exchange endpoints during the linking process you issue access tokens to google for individual google accounts after obtaining account holders consent to link their accounts and share data oauth linking this is the oauth linking flow that sends users to your website for linking the user is redirected to your website to sign in to their account once signed in the user consents to sharing their data on your service with google at that point the user s google account and your service are linked oauth linking supports the authorization code and implicit oauth flows your service must host an oauth 2 0 compliant authorization endpoint for the implicit flow and must expose both an authorization and token exchange endpoint when using the authorization code flow caution for mcp ucp and agent driven flows oauth 2 1 is mandatory and the implicit flow is not supported use the authorization code flow instead note implementing oauth linking is required for all account linking integrations as it is the fallback method for app flip and streamlined flows figure 1 account linking on a user s phone with oauth linking oauth based app flip linking app flip an oauth flow that sends users to your app for linking oauth based app flip linking guides users as they move between your verified android or ios mobile apps and google s platform to review the proposed data access changes and grant their consent to link their account on your platform with their google account to enable app flip your service must support oauth linking or oauth based sign in with google linking using the authorization code flow app flip is supported for both android and ios how it works google app checks if your app is installed on the user s device if the app is found the user is flipped to your app your app gathers consent from the user to link the account with google and then flips back to the google surface if app is not found or an error occurs during the app flip linking process the user is redirected to streamlined or oauth linking flow figure 2 account linking on a user s phone with app flip oauth based streamlined linking streamlined oauth based sign in with google streamlined linking adds sign in with google on top of oauth linking enabling users to complete the linking process without leaving the google surface thereby reducing frictions and drop offs oauth based streamlined linking offers the best user experience with seamless sign in account creation and account linking by combining sign in with google with oauth linking your service must support oauth 2 0 compliant authorization and token exchange endpoints additionally your token exchange endpoint must support json web token jwt assertions and implement the required check and get intents and optionally the create intent note the user never leaves the google surface during this flow so google must show consent on behalf of the 3p in order for the flow to work properly how it works google asserts the user account and passes this information to you if an account exists for the user in your database the user successfully links their google account with their account on your service if no account exists for the user in your database and account creation is supported by your service the user can either create a new 3p account with the asserted information google provides email name and profile picture or choose to sign in and link with another email using oauth linking figure 3 account linking on a user s phone with streamlined linking which flow should you use we recommend implementing all flows to ensure users get the best linking experience the streamlined and app flip flows reduce linking friction as users are able to complete the linking process in very few steps the oauth linking flow has the lowest level of effort and is a good place to start after which you can add on the other linking flows note the oauth linking flow is required for all integrations as it is the fall back for the other flows work with tokens google account linking relies on standard oauth 2 0 token mechanisms you issue access tokens and refresh tokens to google after the user consents to link their account access tokens short lived tokens used by google to access your apis refresh tokens long lived tokens used by google to obtain new access tokens when they expire for detailed protocol contracts and parameter requirements see the token exchange endpoint persistent linking persistent linking is a core requirement for stable integrations it ensures that user accounts remain linked even during transient network failures or periodic credential refreshes to implement persistent linking use a sliding window approach extend the expiration of the existing refresh token instead of rotating it referencing rfc 6749 section 6 this prevents race conditions and unintended unlinking that can occur if a new refresh token is issued but not successfully received or stored by google register with google we ll need details of your oauth 2 0 setup and to share credentials to enable account linking see
