A method and apparatus for providing authentication are disclosed. For example, the method receives a request from a customer to access a service via a first user endpoint device, and sends a first authentication request to the customer for first authentication information. The method then sends a second authentication request to the customer for second authentication information via a second user endpoint device if the first authentication information is received, wherein the first user endpoint device is different from the second user endpoint device. The method then enables the customer to proceed with accessing the service if the second authentication information is received.
