Single sign-on
Signing in with an account you already have elsewhere, like Google or your company login, instead of a new one.
What it is
Single sign-on lets people use an existing identity to get into your app: "Continue with Google", "Sign in with Apple", or a company's Okta login. One account, many apps.
Consumer apps often call it social login. Business apps sell company SSO to larger customers, because it lets IT control who has access.
It's convenient for users, but each provider needs setting up, so pick the one or two your audience actually uses.
How to ask for it
“Let them use their Google.”
“Offer single sign-on with Google as the primary sign-in button, plus email codes as a fallback. Use the Google account's name and photo to pre-fill the user profile.”
"Use their Google" leaves the fallback and data use open; naming single sign-on and the fallback makes the plan complete.
