A cloud services application executing on a cloud computing platform receives from a browser application executing on a customer computer system a request of a user to login to the cloud services application. The cloud services application further receives an indication via the browser application that biometric identifier authentication of the user is supported by the customer computer system, and transmits an indication to the browser application that biometric identifier authentication of the user is enabled for a session that is to be established. The cloud services application transmits a response to the login request, responsive to receipt of the login request, the response prompting the user to input a biometric identifier, and receives a unique identifier (UID) associated with the biometric identifier. The cloud services application searches a list of user profiles, each with an associated one or more UIDs, for a UID that matches the received UID associated with the biometric identifier and transmits an indication to the browser application allowing access to the web service application responsive to finding a UID that matches the received UID associated with the biometric identifier.
