Providing flexible service access using identity provider

An identity provider device comprising:

• a processor;
• and
• memory storing instructions that, when executed by the processor, cause the identity provider device to:
• receive, from a service provider device associated with a service provider, a request for authentication associated with a client device;
• select, from a plurality of access policies, an access policy associated with the service provider, wherein the access policy indicates one or more types of device signals;
• receive one or more device signals associated with one or more characteristics of the client device;
• select, from the one or more device signals and based on the one or more types of device signals indicated in the access policy, at least one device signal associated with at least one characteristic of the client device;
• determine, using a machine learning model that receives the at least one device signal associated with the at least one characteristic of the client device as input, a device trust score for the client device;
• and
• provide, based on the device trust score, an authentication response for determination of an access level associated with access, by the client device, to one or more services associated with the service provider.

A non-transitory, computer-readable medium storing instructions that, when executed by a processor of an identity provider device, cause:

• receiving, from a service provider device associated with a service provider, a request for authentication associated with a client device;
• selecting, from a plurality of access policies, an access policy associated with the service provider, wherein the access policy indicates one or more types of device signals;
• receiving one or more device signals associated with one or more characteristics of the client device;
• selecting, from the one or more device signals and based on the one or more types of device signals indicated in the access policy, at least one device signal associated with at least one characteristic of the client device;
• determining, using a machine learning model that receives the at least one device signal associated with the at least one characteristic of the client device as input, a device trust score for the client device;
• and
• providing, based on the device trust score, an authentication response for determination of an access level associated with access, by the client device, to one or more services associated with the service provider.
