Hello, I don't use the FB app nor FB Messenger to avoid being interrupted by those notifications all the time. Usually when I want to use FB, I just click the Safari icon, choose the FB icon and my iPhone automatically logs me in. In case I want to have two accounts one for private and one for public use, what can I do? There are two potential situations: 1. In parties when somebody I am unfamiliar with asks my FB, I tell that person my FB public account. When I want to make friend with another person, use my private FB account. I want to be able to switch between the two accounts instantly. 2. Joining public social group using my public FB account.
