Seamless credential sharing
Use seamless credential sharing to share credentials across websites and apps. Keep your users signed in and signed up across the web and your apps, avoiding unnecessary password resets and helpdesk calls.
What is seamless credential sharing?
Seamless credential sharing is a set of practices, technologies, and infrastructure that enables Google Password Manager and other services in the Google ecosystem to securely share passwords among your websites and Android apps.
Web and Android developers can implement credential sharing to simplify the sign-in experience for their users. This lets Google Password Manager autofill credentials on domains or Android apps that share the same account management backend.
For example, if a user stores credentials for a domain in Password Manager while using Chrome, Chrome can suggest the autofill of those credentials for another associated domain or Android can suggest the autofill on an associated Android app.
