Hi - this is Maggie from Sendwave. Your Sendwave account was just logged into on a new device called iPhone. If you did not login using this device, you can secure your account asap by (1) changing your Sendwave password and then (2) enabling SMS Login on your account by going to "Me" (on iPhone) or upper righthand menu (on Android) and switching on "Enable SMS login." This will log out all devices from your account and thereafter, require a code texted to your mobile phone to log into your account. Please call our Support Team at 0113 320 7935 for further assistance.
