The codes that need to be entered in the appropriate field are a kind of protection built into the VKontakte social network. When entering them, you should be more careful so that the system does not suspect you of committing illegal actions.
The first code that each user of the VKontakte social network must enter is a verification code sent immediately after registration on the site. To do this, you must indicate your valid mobile phone number in the specially designated field. Subsequently, the code will come exactly to him in the form of a message. Enter the received numbers in the specially designated field on the website. Immediately after that, you will be marked by the social network as a valid user, not a bot (a robotic system that registers non-existent users for further spamming from their accounts).
Subsequently, the procedure for entering the verification code will have to go through again if you decide to change your phone number in the general settings. First, you will need to indicate the code that will come to your old phone number, and then enter the sequence of numbers sent to the specified new phone number. Please note that room changes are allowed no more than three times.
The next code, which users of the social network often have to enter, is a captcha - a sequence of random numbers and letters shown on the screen as an image. This procedure is also a kind of protection against spam, bots and fraudsters. You will come across it often if you have not yet verified your account via cell phone, trying to send a message to a large number of users at once, or posting in several communities at the same time. Just enter the specified sequence of numbers in the field below and press "Enter".
