Is Freemasonry a secret society?

Freemasonry is not a secret society, but lodge meetings, like meetings of many other social and professional associations, are private occasions open only to members.
Freemasons are encouraged to speak openly about their membership, while remembering that they undertake not to use it for their own or anyone else's advancement. As members are sometimes the subject of discrimination which may adversely affect their employment or other aspects of their lives, some Freemasons are understandably reticent about discussing their membership. In common with many other national organisations, Grand Lodge neither maintains nor publishes a list of members and will not disclose names or member's details without their permission.
In circumstances where a conflict of interest might arise or be perceived to exist or when Freemasonry becomes an issue, a Freemason must declare an interest.
The rules and aims of Freemasonry are available to the public. The meeting places and halls used by Freemasons are readily identifiable. Freemasons' Halls are open to the public and 'open days' are held in many provincial centres.
The rituals and ceremonies used by Freemasons to pass on the principles of Freemasonry to new members were first revealed publicly in 1723. They include the traditional forms of recognition used by Freemasons essentially to prove their identity and qualifications when entering a Masonic meeting. These include handshakes which have been much written about and can scarcely be regarded as truly secret today; for mediaeval Freemasons, they were the equivalent of a 'pin number' restricting access only to qualified members.
Many thousands of books have been written on the subject of Freemasonry and are readily available to the general public.
Freemasonry offers spokesmen and briefings for the media and provides talks to interested groups on request. 
Freemasons are proud of their heritage and happy to share it.
