Keep getting Gmail emails saying someone requested a single use code for my Microsoft account. The emails state "if this was not you, don't worry, ignore this, it was probably someone inputting the wrong email" or something along those lines....but I'm getting one a day. Clearly someone unscrupulous has gotten hold of my email address for the account....do I have anything to worry about? I usually use complex passwords. Probably safer to change it when I get home?
