How To Auto Fetch OTP In Angular

Are you looking to auto fetch One Time Password (OTP) in your Angular application? In this tutorial, we will cover how to achieve this using Angular’s built-in features.

Step 1: Create a form for OTP input

First, create a form in your Angular component’s template file for the user to input the OTP.

Step 2: Auto fetch OTP from API

Next, use Angular’s HTTP client to fetch the OTP from an API when the component is initialized.

“`typescript
import { Component, OnInit } from ‘@angular/core’;
import { HttpClient } from ‘@angular/common/http’;

@Component({
selector: ‘app-otp-component’,
templateUrl: ‘./otp.component.html’,
styleUrls: [‘./otp.component.css’]
})
export class OtpComponent implements OnInit {
otp: string;

constructor(private http: HttpClient) { }

ngOnInit() {
this.fetchOtp();
}

fetchOtp() {
this.http.get(‘https://example.com/fetch-otp’).subscribe((data: any) => {
this.otp = data.otp;
});
}

submitOtp() {
// Handle submitting the OTP here
}
}
“`

Step 3: Display the fetched OTP

Finally, display the fetched OTP in the input field in the component’s template.

“`html

“`
