Facebook Rolling Out Ability to Have Multiple Profiles on One Account

Facebook is rolling out the ability to have multiple personal profiles tied to one account. This allows people to separate personal and professional connections or organize profiles by interest.
Up to 4 additional profiles can be created with a unique username. Each profile will have its own feed and connections.
Switching between profiles is easy with no login required. Messaging support across profiles is limited initially but will expand.
Privacy and notification settings don't carry over between profiles. Check settings for each new profile.
Main profile must use real identity. Additional profiles can use any name but can't impersonate others or misrepresent identity.
