Q. How do I install Microsoft Authenticator?

Microsoft Authenticator is the application/service Fairfax County uses for Multi-Factor Authentication (MFA) to verify and authenticate staff. This is required for staff who are using https://portal.office.com inside County facilities as well as those accessing the county network and applications on non-County devices or for users accessing from home or away from the office. Instructions for installing MS Authenticator may be found here. A video of the steps involved may be found here.
