My ex boyfriend told my iPhone * Plus and knows the unlock code to my phone where I am logged into all my accounts such as yahoo email my email is *****@***.com and backup email is M*****@***.com but I do not remember the password to my backup email which is why I had to make another one but he changed my current password on my *****@***.com because I was logged on to the account on my phone. Now he changed my Facebook password which I just changed a couple days ago. It was a password I would not forget I made sure of that now all of a sudden I cannot log into my Facebook account and all my reset password notifications are being sent to my email and he is getting every single one of them. How can I get into my email and change my password and logout of all and any other devises? He is invading my personal privacy and making life very difficult and I just want it to stop please tell me there is a way to recover my account I can tell you the last three passwords that I had on the account I can answer any and all security questions and I have proof that he stole my phone because he was on my messenger messaging my friends saying how he stole my phone and it’s his now I deactivated my wireless service and reported my phone stolen as well as filing a police report. Please help me regain access to my email and Facebook please because he is checking all my personal emails and Facebook notifications and I can’t even get into my account please help me this is very urgent and very unfair he should not be allowed to get away with this and I loose all my personal accounts this sort of thing must happen all the time I just really hope you can help me get my accounts back to where only I can access them
