I received a call from 202-455-8888 regarding authentication for my gmail account but I haven't logged in, so what do I do now?
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!
There are two possibilities:
Someone has your password and is trying to use it, but fails the 2FA. Change your password!
Someone is trying to register a new account or 2FA to an existing one, but has (possibly accidentally) added your phone number instead of their own.
It's possible that there's just a minor difference in your numbers and it's simply a typo, e.g. the Ghostbusters are trying to register +1-311-555-3268 instead of +1-311-555-2368.
It's safer this way, when there's just an automaton that gives you information, but if someone calls from number +1 202-455-8888 and tells them that they are from Google, it's probably still a scam, because Caller ID spoofing is relatively easy. You shouldn't tell them anything. If they really were Google, they would already know it anyway.
