Lays down the steps to send an email link for sign-in (passwordless sign-in). Removes the hassle of remembering passwords for your end-users & for you as developers to implement "forgot password" or "verify-email" workflows.

signInWithEmailLink.ts

async sendEmail(email: string) {
    const actionCodeSettings = {
      // URL you want to redirect back to. The domain (www.example.com) for this
      // URL must be whitelisted in the Firebase Console.
      url: environment.redirectURL,
      // This must be true.
      handleCodeInApp: true
    };

    try {
      await this.afAuth.auth.sendSignInLinkToEmail(
        email,
        actionCodeSettings
      );
      // 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);
      // Material snackbar for informing user:https://material.angular.io/components/snack-bar/overview
      this.snackBarService.openSnackBar(sendEmail.welcome, 'welcome');
    } catch (error) {
      // Some error occurred, you can inspect the code: error.code
      this.handleError(error);
    } finally {
      // I have a loader in place switch it off
      this.setLoadingState(false);
    }
