# Authentication Methods
Crema supports 4 types of authentication methods as following. By default Crema comes with the firebase authentication method. You can switch between them by the following some steps written in the particular Auth method.
{% hint style="info" %}
Don't forgot to change header in case you have different from "Authorization"
{% endhint %}
1. **JWT Auth**
JSON Web Token is a proposed Internet standard for creating data with an optional signature.
Crema demo is linked with the Mongoose server. You can find our predefined APIs [here](https://docs.cremawork.com/v-3/servers/mongoose)
To integrate JWT Auth you need to follow the following steps.
1. Open the `src/@`crema`/services/auth/jwt-auth/index.js` file and update baseURL of your server like below
```
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 `src/@`crema`/services/auth/jwt-auth/index.js` and change the
```
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');
}
};
```
1. Wrapp ` with `` Component in the `src/App.js` file like below.
```
const App = () => (
...
//Add the line
...
);
export default App;
```
2. Uncomment the JWT Auth method like below in the `src/@crema/utility/AuthHooks.js` file
```
// ForJWT Auth
import {getUserFromJwtAuth} from './helper/AuthHelper';
import {
useJWTAuth,
useJWTAuthActions,
} from '../services/auth/jwt-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,
};
};
```
3. In the final step, we need to call the`` tag in the `src/pages/auth/Signin/index.js` file like below and do the same for **Signup**.
```
const SignIn = () => {
return (
...
...
);
};
export default SignIn;
```
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 `src/@crema/services/auth/firebase/firebase.js` file and update **firebaseConfig** for your app like below
```
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. Wrapp ` with `` Component in the `src/App.js` file like below.
```
const App = () => (
...
//Add the line
...
);
export default App;
```
4. Uncomment the Firebase Auth method like below in the `src/@crema/utility/AuthHooks.js` file
```
import {
useFirebase,
useFirebaseActions,
} from '../services/auth/firebase/FirebaseAuthProvider';
import {getUserFromFirebase} from './helper/AuthHelper';
export const useAuthUser = () => {
const {user, isAuthenticated, isLoading} = useFirebase();
return {
isLoading,
isAuthenticated,
user: getUserFromFirebase(user),
};
};
export const useAuthMethod = () => {
const {
signInWithEmailAndPassword,
createUserWithEmailAndPassword,
signInWithPopup,
logout,
} = useFirebaseActions();
return {
signInWithEmailAndPassword,
createUserWithEmailAndPassword,
signInWithPopup,
logout,
};
};
```
5. In the final step, we need to call the`` tag in the `src/pages/auth/Signin/index.js` file like below and do the same for **Signup**.
```
const SignIn = () => {
return (
...
...
);
};
export default SignIn;
```
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 `src/@crema/services/auth/aws-cognito/aws-exports.js` file and update **awsConfig** for your app like below
```
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. Wrapp ` with `` Component in the `src/App.js` file like below.
```
const App = () => (
...
//Add the line
...
);
export default App;
```
4. Uncomment the AWS Auth method like below in the `src/@crema/utility/AuthHooks.js` file
```
import {getUserFromAWS} from './helper/AuthHelper';
import {
useAwsCognito,
useAwsCognitoActions,
} from '../services/auth/aws-cognito/AWSAuthProvider';
export const useAuthUser = () => {
const {user, isAuthenticated, isLoading} = useAwsCognito();
return {
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 `src/pages/auth/Signin/index.js` file like below and do the same for **Signup**.
```
const SignIn = () => {
return (
...
...
);
};
export default SignIn;
```
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 `src/@crema/services/auth/auth0/auth0Config.js` file and update Auth0Config for your app like below
```
const Auth0Config = async () => {
return await createAuth0Client({
client_id: 'XXXXXXXXXX',
domain: 'XXXXXXXXXX.auth0.com',
redirect_uri: 'XXXXXXXXXX',
audience: 'https://XXXXXXXXXX.auth0.com/userinfo',
});
};
```
3. Wrapp ` with `` Component in the `src/App.js` file like below.
```
....
import Auth0Provider from "./@crema/services/auth/auth0/Auth0Provider";
const App = () => (
...
//Add the line
...
);
export default App;
```
4. Uncomment the Auth0 Auth method like below in the `src/@crema/utility/AuthHooks.js` file
```
export const useAuthUser = () => {
const {user, isAuthenticated, isLoading} = useAuth0();
console.log(
'user, isAuthenticated, isLoading',
user,
isAuthenticated,
isLoading,
);
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.
