How to change mail in firebase account

To change the email address associated with your Firebase account, you'll need to follow these steps:

Method 1: Update email address through Firebase Console

1. Sign in to the Firebase Console with your current email address and password.
2. Click on the gear icon () in the top right corner of the Firebase Console dashboard.
3. Select "Settings" from the dropdown menu.
4. Scroll down to the "Account" section.
5. Click on the "Edit" button next to "Email address".
6. Enter your new email address and confirm it by re-entering it in the "Confirm email address" field.
7. Click "Save" to update your email address.

Method 2: Update email address through Firebase CLI

1. Install the Firebase CLI by running npm install -g firebase-tools or yarn global add firebase-tools.
2. Run firebase login to authenticate with your Firebase account.
3. Run firebase settings:get to retrieve your current Firebase settings.
4. Update the email field in the settings file to your new email address.
5. Run firebase settings:update to update your Firebase settings.

Method 3: Update email address through Firebase SDKs

If you're using a Firebase SDK (e.g., Firebase JavaScript SDK, Firebase Android SDK, etc.), you can update your email address programmatically using the SDK's API.

For example, in the Firebase JavaScript SDK, you can use the firebase.auth().currentUser.updateEmail() method to update your email address:

import { auth } from 'firebase/app';
import { updateEmail } from 'firebase/auth';

const user = auth().currentUser;
user.updateEmail('[email protected]').then(() => {
  console.log('Email updated successfully!');
}).catch((error) => {
  console.error('Error updating email:', error);
});

Important notes:

• When you update your email address, you'll need to verify your new email address by following the verification link sent to your new email address.
• If you're using Firebase Authentication, updating your email address will also update your authentication credentials.
• If you're using Firebase Realtime Database or Cloud Firestore, updating your email address may affect your database permissions and access.

Remember to always keep your email address up to date to ensure you receive important Firebase notifications and updates!
