Implementing Two-Factor Authentication (2FA)

Two-factor authentication (2FA) is a multifactor security process where users must authenticate their identity with two different means. This ensures better protection of secured assets and information.

Traditional username and password combinations are prone to hacking and getting hacked has been on the rise. Implementing 2FA authentication will prevent hackers from accessing your accounts even if your password is stolen. 2FA is a recommended practice for securing all your online accounts and devices to protect sensitive information losses.

You will need a different set of components with features ranging from creating the secret codes, accessing and authenticating.

OTP:

Time-based One-Time Password involves generating a one-time password from a shared secret key and the current timestamp using cryptographic algorithms. These libraries will help you generate secrete one-time passwords

SMS

Typically the OTP codes are sent to the user's mobile phone using SMS. This also helps to validate the user's mobile number correctness. The user can then enter the secret code into the application to complete the multifactor authentication. The below libraries will help in sending SMS from your application.

Email

The unique generated one-time password is sent via email to the user. The user uses the code from the email and enters the code into the application to confirm the authentication.

Biometric Authentication

Using Biometrics for authentication has been made easy with mobile devices. Biometrics can include different choices, such as using fingerprints, voice, and face as the secondary authentication mechanism.

Push Notifications

Typically, push notifications are sent to your mobile app to authorize login requests. It will include the details of the access device details and once authorized, the login to the application is allowed. Below libraries help in implementing the push notification-based authorization.
