I have enabled multi-factor authentication for my Gmail. When I need to log in to my mail, I should enter an OTP which is sent to my phone number.
I got a call from this number, even though I did not sign in to my mail, and it said "Your verification code is ******". Does this mean that my account is at risk? I have checked my mailbox, and there is no attempt to login.
I found this on the Google support forum:
Yes, this number is definitely Google's number used for various verification purposes. Just be aware of this: If you initiate the verification process, then it is perfectly safe. If, on the other hand, somebody else sends you a code from this # (it is possible) and then asks you to give them the code verbally or by text, they are trying to scam you! So to be safe, do not ever give the code to anybody, no matter how convincing their story is!
