how can i send email otp using ionic and firebase in an android app?

[ionicsiva]

I have the question: How can I send email OTP using Ionic and Firebase in an Android app? Like many others here, I want to create a system where an OTP is sent when a on the frontend. I've searched everywhere for a solution.

I'm using Ionic with Angular and the Capacitor plugin for this

#ionic7 #firebase #email #otp

This is an example from the Capacitor Firebase Authentication plugin:

import { FirebaseAuthentication } from '@capacitor-firebase/authentication';

const sendSignInLinkToEmail = async () => {
  const email = '[email protected]';
  await FirebaseAuthentication.sendSignInLinkToEmail({
    email,
    actionCodeSettings: {
      // URL you want to redirect back to. The domain (www.example.com) for this
      // URL must be in the authorized domains list in the Firebase Console.
      url: 'https://www.example.com/finishSignUp?cartId=1234',
      // This must be true.
      handleCodeInApp: true,
      iOS: {
        bundleId: 'com.example.ios',
      },
      android: {
        packageName: 'com.example.android',
        installApp: true,
        minimumVersion: '12',
      },
      dynamicLinkDomain: 'example.page.link',
    },
  });
  // The link was successfully sent. Inform the user.
  // Save the email locally so you don't need to ask the user for it again
  // if they open the link on the same device.
  window.localStorage.setItem('emailForSignIn', email);
};
