Authentication data for providing access to a resource to a user is received from a requester. The authentication data encapsulates data required by both a first authentication solution and a second authentication procedure both for providing access to a resource. The first and second authentication solutions can differ in authentication modality with the second authentication solution utilizing at least one machine learning model. Thereafter, using the received authentication data, both of the first and second authentication solutions are initiated. Authentication results are received from both of the first and second authentication solutions. The requester is provided with access to the resource if the both of the received authentication results indicate that authentication of the user was successful. Related apparatus, systems, techniques and articles are also described.
