Two-factor Authentication is an extra layer of security that is known as "multi factor authentication". In addition to using a username and password to login, users are also required to enter another unique form of identification. That can either be random characters from a memorable word, that only the user knows, or using an authenticator on their phone to generate a unique verification code.
Enabling a memorable word
To use this security feature you must subscribe to the Enterprise Edition of Glasscubes. To enable it, navigate to Settings>Password control and check the 'Enable Memorable-word Two Factor Authentication' box and then press 'Save'.
Once enabled users will be prompted to setup a memorable word the next time they login. The word must be at least 6 characters long. It can contain both letters and numbers and is not case sensitive.
Once the memorable word is set up, they will be asked to type in 3 randomly chosen characters of their word each time they login.
If a user forgets their memorable word, there is a link on the sign in popup to reset it.
