Introduction to 732873

If you’ve ever lost a password for an email account or any online account in general, you must’ve tried to reset it. If you’ve verified your phone number, the site gives you the option to reset it using your phone. On selecting this the site will send an automated message with a one-time password. This process is used by the website to verify that the person trying to reset the password for your account is indeed you. This one-time password you receive will mostly be from the number 732873. In this article, I’m going to try and inform you of everything about the number 732873 and the service that owns this number. I’ll also provide a tutorial on enabling two-factor authorization for your Microsft account. So, let’s dive in.

Multi-factor Authentication

If you regularly use services like Gmail, Steam, Outlook, etc you might have come across the term like Two-factor authorization or Multi-factor authorization. This is one of the most popular methods of enabling electronic authorization for your account. MFA even though not immune, really secures the login attempts to your accounts. The name Multi-Factor authorization was given to the method as the method has two or more factors. The first one being the password set by the user, the method does not provide access to the account unless another piece of evidence is provided. The evidence other than the password can be of different forms.


  • The most popular form of the second factor is something you know. Most websites when creating an online account will ask you to set a security question and an answer that only you know about. The user set password also falls under this category. This type of factor can contain alpha-numeric characters. It is generally assumed to be memorized and not be noted down anywhere for maximum security.
  • Another popular factor is something you have. This factor can be of different types. This type of MFA is very secure as it requires a token that is very unique and hard to replicate. It can be a small physical device, or it can be software on a laptop or mobile phone. This method is also becoming very popular nowadays. Steam requires a token number from Steam’s mobile app for accessing it on a new PC. This token number is never the same and changes every 30 seconds or so. This increases the security even further.
  • Something you are, this is yet another common form of factor that is found in almost every smartphone nowadays. This makes use of the biological characteristics of the person. This includes your fingerprint, retina, voice, etc.
  • The last factor form is somewhere you are. This makes use of your literal physical location using the GPS on your device. This is again used by sites like Gmail and Facebook. They send a warning whenever the login attempt comes from an unusual location.

At the time of writing, SMS is the most used and broadly accepted form of MFA. It makes sense to discuss its merits and demerits:


  • Since all the tokens can be received on the same device, there is no need to carry multiple devices at all times.
  • The tokens change dynamically and are never the same. This increases the security of login attempts.


  • Phishing attacks are still a major threat. Attacker can send links to an identical-looking fake website and extract any useful information.
  • Mobile phones can get stolen.
  • SIM cloning can give hackers access to several mobile phone connections.

Even though it has its demerits, 2FA using SMS has been mandated in many countries for online transactions because of its security and accessibility.


This is our main topic of discussion today. The majority of the one time passwords and security tokens that you get on your phone are from this number. From the number itself, you can say it’s not used by a real person but by a company. The first time I received an OTP from this number, I got curious to know more about it. This number is owned by the service verifyphonesms.com. This is a service that provides SMS-based two-factor authorization services across the globe. Websites and corporations like Microsoft, Steam, Xbox, and several others use this service for 2FA on their sites.

Is Someone Trying To Hack You?

Not necessarily. I say not necessarily because someone may be trying to gain access to your account. If you are the one making a login attempt and get an OTP from this number, then you don’t need to worry. The problem comes when you weren’t even trying to make login attempts and you receive messages from this number. This means that someone is trying to access your account. In these circumstances, I would highly recommend changing your password as soon as possible. If the attacker is successful in making a login attempt then this could very harmful.

This could result in the loss of your personal and sensitive data like Bank Information, passwords for other accounts, your messages, and several other data. The attacker can also change the password of your account making it inaccessible to you. This is why in case if you get a message from the number 732873 without making a login attempt or without a viable reason then it is highly recommended to change your password as soon as possible. This is especially recommended if you’re getting these messages again and again. Read more about Single Click System Hack
