When confirming a phone number, you usually have to wait for an encrypted SMS message to re-enter the app or website. However, a growing number of users are reporting a changing process: Google is the sender of the SMS, which comes from the user's mobile phone.
If you got it Suspicious SMS messages were sent from your mobile phone to unknown numbers, it can be a process to confirm this one. Google says it's "normal", even though the process is very small in form and content.
Google Confirmation
Several users, most from India but others from Europe and the United States, have joined Google forums for the appearance of suspicious messages sent by their superiors. The messages include the code and the text "Google verifies your phone on this device", as well as a link to the help page.
Code of principle and, in particular, the fact that it is messages they are sent to local numbers that vary from one user to another and not officially listed as Google's are the ones that set up an alarm for users, fearing it is a spam or some form of fraud.
Still, it seems standard process validation process which, for some reason, has become more effective in recent days. Google describes it in its support page:
If you set up a Google account, you can enter your phone number. If you do, we'll make sure the number is yours.
For security reasons, we will also use it periodically to make sure it is still your phone number. When we do, You can receive SMS from Google or your device may send messages to Google. An example of a message would be "Google looks at the phone number of this device."
This explains why, although the method of making the check looks aggressive, it is very touching additional costs to the user by sending the specified message. Not only that, but several users wonder how much Google can send without informing you (many of these messages were sent at one start, while the user was not using the mobile phone).
The Google team is informed of this approach and support structures mean it they work for a solution. How it will come and when it will come again, so in the meantime if you want to make sure it doesn't happen to you, all you can do is remove the SMS permission from the Google app.
