A method is provided for authorizing an authenticated user into a teleconference session as a participant that avoids some of the costs and disadvantages of doing so in the prior art. The authorization is a combination of the enterprise user's authentication at work and cryptographic authorization to the teleconference system by the inviter. When a user goes to work and connects with his or her office computer to the network of the user's employer, a secure single sign-on (SSO) access control procedure is executed. In a secure single sign-on (SSO) access control procedure, the user submits authentication information, such as a user name and password, to an identity provider and receives back a credential token when the identity provider determines that the user name/password pair is valid. The credential token is saved on the user's computer and used for further authentication.
