All of Privy’s authentication flows can be whitelabeled, from email and SMS passwordless flows to social logins and passkeys. To whitelabel Privy’s passwordless email flow, use the `useLoginWithEmail` hook. Then, call `sendCode` and `loginWithCode` with the desired email address. ```tsx theme={"system"} import {useLoginWithEmail} from '@privy-io/react-auth'; ``` ```tsx theme={"system"} const {sendCode, loginWithCode} = useLoginWithEmail(); sendCode({email: 'test@test.com'}); loginWithCode({code: '123456'}); ``` Learn more about [email authentication and tracking login flow state](/authentication/user-authentication/login-methods/email). To whitelabel the passwordless SMS flow, use the `useLoginWithSms` hook. Then, call `sendCode` and `loginWithCode` with the desired phone number. ```tsx theme={"system"} import {useLoginWithSms} from '@privy-io/react-auth'; ``` ```tsx theme={"system"} const {sendCode, loginWithCode} = useLoginWithSms(); sendCode({phoneNumber: '+1234567890'}); loginWithCode({code: '123456'}); ``` Learn more about [SMS authentication and tracking login flow state](/authentication/user-authentication/login-methods/sms). To whitelabel social login, use the `useLoginWithOAuth` hook and call `initOAuth` with your desired social login provider. ```tsx theme={"system"} import {useLoginWithOAuth} from '@privy-io/react-auth'; ``` ```tsx theme={"system"} const {initOAuth} = useLoginWithOAuth(); initOAuth({provider: 'google'}); ``` Learn more about [social logins and tracking login flow state](/authentication/user-authentication/login-methods/oauth). To whitelabel passkeys, use the `useLoginWithPasskey` hook and call `loginWithPasskey`. ```tsx theme={"system"} import {useLoginWithPasskey} from '@privy-io/react-auth'; ``` ```tsx theme={"system"} const {loginWithPasskey} = useLoginWithPasskey(); loginWithPasskey(); ``` To sign up with a passkey: ```tsx theme={"system"} import {useSignupWithPasskey} from '@privy-io/react-auth'; ``` ```tsx theme={"system"} const {signupWithPasskey} = useSignupWithPasskey(); signupWithPasskey(); ``` To link a passkey to an existing user: ```tsx theme={"system"} import {useLinkWithPasskey} from '@privy-io/react-auth'; ``` ```tsx theme={"system"} const {linkWithPasskey} = useLinkWithPasskey(); linkWithPasskey(); ``` Learn more about [passkeys and tracking login flow state](/authentication/user-authentication/login-methods/passkey). To whitelabel the Telegram login flow, it’s as simple as using the `useLoginWithTelegram` hook and calling `login`. ```tsx theme={"system"} import {useLoginWithTelegram} from '@privy-io/react-auth'; ``` ```tsx theme={"system"} const {login, state} = useLoginWithTelegram(); login(); ``` Learn more about [Telegram authentication and tracking login flow state](/authentication/user-authentication/login-methods/telegram).
