This was sent to me in regards to scams to watch out for. In this case, the scammer claims that an imposter tried to hack your account and that it might be at risk. The phone number is connecting you to a scammer. Scammers know that many people are wary of them and they will try to fool you into thinking that they are protecting you from other fraudsters. Always verify the email that it comes from. In this case it came from no-reaply@coin2fa.com. That is not the email domain for coinbase, It is also misspelled. Below is a copy of the email that was sent to us. Be aware and be smart. The phone number when entered into an internet search did not say it was from coinbase.
