Projects

  • Multi-Factor Authentication for Amazon WorkSpaces

    Multi-factor authentication (MFA) for Amazon WorkSpaces is now available. MFA can provide you with an additional layer of security during the authentication process. Users must validate their identify by providing something they know (e.g. password), as well as something they have (e.g. hardware or software generated one-time password (OTP))
