Guide to the SMS Astral Two-Factor Authentication Process (2FA)


At Astral SMS, your data is safe! We take security seriously and implement 2-factor authentication to protect your account from unauthorized access. By utilizing this method, the risk of fraud is minimal. Our system will not only prompt you for your username and password but also for a unique code (OTP) sent to your mobile device via SMS. This messenger verification code is generated by our system and is valid for a limited time, making it a secure method of verifying your identity.

How does 2-Factor Authentication work?

The two-factor authentication definition states that 2FA verifies a user’s identity by requiring them to provide two forms of identification. The two factors used in 2FA are typically something only you know, such as a password, and an electronic item you possess, such as your mobile device.

Here is a general overview of how our easy and secure 2-factor authentication solution works:

  1. You start to sign in to your account on either our website or the app on your phone.
  2. You will then be prompted to enter a password.
  3. Once the password is entered and verified as correct, we will ask you for a second form of identification.
  4. This can be done by sending a messenger password via SMS or an authenticator app to your phone or device.
  5. As soon as you enter the correct second form of identification, we will verify your identity and allow access to your account.

How do you set up a 2-Factor Authentication?

Setting up a safe two-factor authentication (2FA) for SMS messaging just takes a couple of minutes.

  1. Sign in to the account you want to secure with 2FA.
  2. Look for an option in the account settings related to 2FA or security.
  3. Enable 2FA and choose SMS messaging to receive the verification code.
  4. Enter your mobile phone number and verify it with a code sent via SMS.
  5. Once you’ve verified your phone number, you’ll be asked to enter a verification code every time you sign in.

With SMS Astral, you can connect your application via API and send the 2FA code to the client. This way, you can ensure a secure and seamless experience for your clients while they access your services.

What are the two Factors used in 2 Factor authentication?

The main requirements of two-factor authentication (2FA) are to use two forms of identification to verify your identity. These are typically something only you would know, such as a password or PIN and an additional code to your phone or security token.

Factor 1: Something only you have knowledge of: this is typically a password or PIN that you have memorized.

Factor 2: Something only you have access to. This is typically a security token or a code sent to a phone via SMS or OTP (One-time-password) in text. This type of password is valid for only one login session or transaction. Once you have logged in or completed a transaction, the OTP is no longer valid, and a new one is required for any subsequent logins or transactions. Our text OTPs provide an additional layer of security for all your transactions. As they are unique, they help prevent unauthorized access to accounts or transactions, even if the first password is compromised.

Here’s an example of how two-factor authentication (2FA) might work in your day-to-day SMS messaging service:

  1. You sign in to the SMS Astral messaging service by entering your username and password.
  2. We send a verification code to your mobile phone via SMS.
  3. You will then enter the verification code on our website or mobile app to complete the login process.

In this example, your password (something only you know) is the first authentication factor.

The verification code sent to your phone is the second factor of authentication. Only by providing the correct password and additional verification OTP can you successfully sign in to your account.

Is 2 Factor Authentication good?

The benefit of two-factor authentication offered by SMS Astral’s 2-Step verification solution is its effectiveness and cost-efficiency in authenticating customers. But it comes with many additional advantages.

Increased security: By requiring a second form of identification beyond just a password, 2FA makes it much more difficult for attackers to gain unauthorized access to an account.

Protection against phishing: 2FA helps protect against phishing attacks, in which an attacker attempts to trick you into entering their password on a fake website. With 2FA, even if an attacker can steal a password, they won’t be able to access the account without your physical phone or the ability to receive the verification code.

Protection against SIM card swap attacks: 2FA can also help protect against SIM swap attacks, in which an attacker can gain control of a phone number and intercept the verification code.

Easy to use: Our 2FA requires minimal effort to set up and can be enabled on the SMS Astral messaging app with just a few clicks.

No additional device is required: With 2FA via SMS, you don’t need any additional device as long as you have a phone with SMS capability.
