I found out that someone is using the Verzion Message+ app to see every text message that I send and receive. I don't want them doing this, but it's not a situation where I can confront them, because I don't know who they are. I know in the past I used it on my tablet for own use and I had to go through an authentication process. I know this person must have had to go through the same to gain access to my messages. Any help or tips on how I can block this person from doing this anymore from my end? I'm downloading the app now on my phone to familiarize myself again with the authentication process. I'm hoping there is a way I can change a password or passcode to lock the other person out.
