# Authentication Methods Crema supports 4 types of authentication methods as follows. By default, Crema comes with the firebase authentication method. You can switch between them by following some steps written in the particular Auth method. {% hint style="info" %} Don't forget to change the header in case you have a different form "Authorization" {% endhint %} 1. **JWT Auth** JSON Web Token is a proposed Internet standard for creating data with an optional signature. The Crema demo is linked with the Mongoose server. You can find our predefined APIs [here](broken://pages/4h26dbVTkxOQZr5lDRO1) To integrate JWT Auth you need to follow the following steps. 1. Open the `libs/services/auth/src/jwt-auth/index.js` file and update baseURL of your server like below ```javascript const jwtAxios = axios.create({ baseURL: 'YOUR_API_URL HERE', headers: { 'Content-Type': 'application/json', }, }); ``` 2. Set header token in the axios, go to the file `libs/services/auth/src/jwt-auth/index.js` and change the ```javascript export const setAuthToken = (token) => { if (token) { jwtAxios.defaults.headers.common['Authorization'] = 'Bearer ' + token;// Change this according your requirement localStorage.setItem('token', token); } else { delete jwtAxios.defaults.headers.common['Authorization']; localStorage.removeItem('token'); } }; ``` 3. Update the AppAuthProvider component in the file `apps/source/src/core/AppAuthProvider/index.js` like below. ```javascript const AppAuthProvider = ({children}) => { const {fetchStart, fetchSuccess, fetchError, showMessage} = useInfoViewActionsContext(); return ( {children} ); }; export default AppAuthProvider; ``` 4. Uncomment the JWT Auth method like below in the `libs/hooks/src/AuthHooks.js` file and comment out the previous hooks ```javascript // ForJWT Auth import { getUserFromJwtAuth } from '@crema/helpers/AuthHelper'; import { useJWTAuth, useJWTAuthActions, } from "@crema/services/auth/JWTAuthProvider"; export const useAuthUser = () => { const { user, isAuthenticated, isLoading } = useJWTAuth(); return { isLoading, isAuthenticated, user: getUserFromJwtAuth(user), }; }; export const useAuthMethod = () => { const { signInUser, signUpUser, logout } = useJWTAuthActions(); return { signInUser, logout, signUpUser, }; }; ``` 5. In the final step, we need to call the`` tag in the `apps/source/src/modules/auth/Signin/index.js` file like below and do the same for **Signup**. ```javascript import { SigninJwtAuth } from '@crema/modules/auth/SignIn'; export default SigninJwtAuth; ``` 2. **Firebase** Firebase security applies Google's internal expertise to easily build app sign-ins. Develop simple, free multi-platform sign-in with Firebase Authentication*.* To integrate Firebase Auth you need to follow the following steps. 1. Configure your app [here](https://firebase.google.com/docs/auth) 2. Open the `libs/services/auth/src/firebase/firebase.js` file and update **firebaseConfig** for your app like below ```javascript const firebaseConfig = { apiKey: 'XXXXXXXXXXXXXXXXXXX', authDomain: 'XXXXXXXXXX.firebaseapp.com', projectId: 'XXXXXXXXXX', storageBucket: 'XXXXXXXXXX.appspot.com', messagingSenderId: 'XXXXXXXXXX', appId: '1:XXXXXXXXXX:web:XXXXXXXXXX', measurementId: 'G-XXXXXXXXXX', }; ``` 3. Update the AppAuthProvider component in the file `apps/source/src/core/AppAuthProvider/index.js` like below. ```javascript const AppAuthProvider = ({children}) => { const {fetchStart, fetchSuccess, fetchError, showMessage} = useInfoViewActionsContext(); return ( {children} ); }; ``` 4. Uncomment the Firebase Auth method like below in the `libs/hooks/src/AuthHooks.js` file ```javascript //For Firebase Auth import { useFirebase, useFirebaseActions, } from '@crema/services/auth/FirebaseAuthProvider'; import { getUserFromFirebase } from '@crema/helpers/AuthHelper'; export const useAuthUser = () => { const { user, isAuthenticated, isLoading } = useFirebase(); return { isLoading, isAuthenticated, user: getUserFromFirebase(user), }; }; export const useAuthMethod = () => { const { logInWithEmailAndPassword, registerUserWithEmailAndPassword, logInWithPopup, logout, } = useFirebaseActions(); return { logInWithEmailAndPassword, registerUserWithEmailAndPassword, logInWithPopup, logout, }; }; ``` 5. In the final step, we need to call the`` tag in the `apps/source/src/modules/auth/Signin/index.js` file like below and do the same for **Signup**. ```javascript import { SigninFirebase } from '@crema/modules/auth/SignIn'; export default SigninFirebase; ``` 3. **AWS** Amazon Cognito lets you add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily*.* To integrate AWS Auth you need to follow the following steps. 1. Configure your app [here](https://docs.aws.amazon.com/cognito/latest/developerguide/getting-started-with-identity-pools.html) 2. Open the `libs/services/auth/src/aws-cognito/aws-exports.js` file and update **awsConfig** for your app like below ```javascript export const awsConfig = { aws_project_region: 'us-east-1', aws_cognito_identity_pool_id: 'us-east-1:XXXXXXXXXX, aws_cognito_region: 'us-east-1', aws_user_pools_id: 'us-east-XXXXXXXXXX', aws_user_pools_web_client_id: 'XXXXXXXXXX', oauth: { domain: 'XXXXXXXXXX.auth.us-east-1.amazoncognito.com', scope: [ 'phone', 'email', 'openid', 'profile', 'aws.cognito.signin.user.admin', ], redirectSignIn: 'http://localhost:3000/', redirectSignOut: 'http://localhost:3000/', responseType: 'code', }, federationTarget: 'COGNITO_USER_POOLS', }; ``` 3. Update the AppAuthProvider component in the file `apps/source/src/core/AppAuthProvider/index.js` like below. ```javascript const AppAuthProvider = ({children}) => { const {fetchStart, fetchSuccess, fetchError, showMessage} = useInfoViewActionsContext(); return ( {children} ); }; ``` 4. Uncomment the AWS Auth method like below in the `libs/hooks/src/AuthHooks.js` file ```javascript // For AWS Auth import {getUserFromAWS} from '@crema/helpers/AuthHelper'; import { useAwsCognito, useAwsCognitoActions, } from '@crema/services/auth/AWSAuthProvider'; export const useAuthUser = () => { const {auth, user, isAuthenticated, isLoading} = useAwsCognito(); return { auth, isLoading, isAuthenticated, user: getUserFromAWS(user), }; }; export const useAuthMethod = () => { const { signIn, signUpCognitoUser, confirmCognitoUserSignup, logout, } = useAwsCognitoActions(); return { signIn, signUpCognitoUser, confirmCognitoUserSignup, logout, }; }; ``` 5. In the final step, we need to call the`` tag in the `apps/source/src/modules/auth/Signin/index.js` file like below and do the same for **Signup**. ```javascript import { SigninAwsCognito } from '@crema/modules/auth/SignIn'; export default SigninAwsCognito; ``` 4. **Auth0** Rapidly integrate *authentication* and authorization for web, mobile, and legacy applications*.* To integrate. Auth0 you need to follow the following steps. 1. Configure your app [here](https://auth0.com/docs/api) 2. Open the `libs/services/auth/src/auth0/auth0Config.js` file and update Auth0Config for your app like below ```javascript const Auth0Config = async () => { return await createAuth0Client({ client_id: 'XXXXXXXXXX', domain: 'XXXXXXXXXX.auth0.com', redirect_uri: 'XXXXXXXXXX', audience: 'https://XXXXXXXXXX.auth0.com/userinfo', }); }; ``` 3. Update the AppAuthProvider component in the file `apps/source/src/core/AppAuthProvider/index.js` like below. ```javascript const AppAuthProvider = ({children}) => { return {children}; }; ``` 4. Wrap ` with `<`AppAuthProvider `>` Component in the `apps/source/`src/core/AppAuthProvider/index`.js` a file like below. ```javascript //For Auth0 import { useAuth0 } from '@auth0/auth0-react'; import { useMemo } from 'react'; import { getUserFromAuth0 } from '@crema/helpers/AuthHelper'; export const useAuthUser = () => { const { user, isAuthenticated, isLoading } = useAuth0(); return { isLoading, isAuthenticated, user: useMemo(() => getUserFromAuth0(user), []), }; }; export const useAuthMethod = () => { const { loginWithRedirect, logout } = useAuth0(); return { loginWithRedirect, logout }; }; ``` 5. In the final step, we need to call **loginWithRedirect** method on the Login button. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
