How do I know which chats are protected?
All chats with other BBM Enterprise or BBM Protected users are protected with an extra layer of encryption and security. Additionally, your administrator can turn on the Protected Plus feature, so all your chats are protected, even if you're chatting with a contact that's using BBM.
If a chat is protected, Protected. Enter a Message appears in the message field at the bottom of the screen before you start typing a message, and text you type appears in blue before you send it.
To check if your administrator turned on the Protected Plus feature, tap > > Enterprise Policies, and check if Protected Plus is listed under Features Turned On.
