First of all, Im not using IoS to access my Coinbase app, mostly on Android. Clearly someone is accessing my account but how? My password is difficult and Im not noob in terms of account security. How did they know the email? Also for that authorization email to be sent to me, it requires login. With just one click to that "Blue Button" at email, it will grant the user to access the whole account. There is also no location of IoS and IP address compare to the usual authorization email which include the location of where Coinbase account being opened.
Will changed password now.
