Developers can use Privy to prompt users to link additional accounts (such as a wallet or Discord profile) at any point in their user journey, not just during login. This is key to Privy’s progressive onboarding: improving conversion and UX by requiring users to complete onboarding steps (e.g. connecting an account) only when necessary.
The React SDK supports linking all supported account types via our modal-guided link methods. To prompt a user to link an account, use the respective method from the useLinkAccount hook:

Users are only permitted to link a single account for a given account type, except for wallets and passkeys. Concretely, a user may link at most one email address, but can link as many wallets and passkeys as they’d like.
Sample prompt to link a user's email after they have logged inBelow is an example button for prompting a user to link an email to their account:
import {useLinkAccount} from '@privy-io/react-auth';

function LinkOptions() {
    const {linkEmail, linkGoogle, linkWallet} = useLinkAccount();

    return (
        <div className="link-options">
            <button onClick={linkEmail}>Link Email to user</button>
            <button onClick={linkGoogle}>Link Google account to user</button>
            <button onClick={linkWallet}>Link Wallet to user</button>
        </div>
    );
}

​
Callbacks

You can optionally register an onSuccess or onError callback on the useLinkAccount hook.
const {linkGoogle} = useLinkAccount({
    onSuccess: ({user, linkMethod, linkedAccount}) => {
        console.log('Linked account to user ', linkedAccount);
    },
    onError: (error) => {
        console.error('Failed to link account with error ', error)
    }
})
​
onSuccess
({user: User, linkMethod: string, linkedAccount: linkedAccount}) => void
Optional callback to run after a user successfully links an account.
​
onError
(error: string) => void
Optional callback to run after there is an error during account linkage.
Looking for whitelabel link methods? Our useLoginWith<AccountType> hooks allow will link an account to a user, provided that the user is already logged in whenever the authentication flow is completed.
