Patent attributes
An access management system is disclosed that can provide access to resources by password-less authentication. The access management system can provide multiple layers of security for authentication taking into account risk factors (e.g., device, location, etc.) to ensure authentication without compromising access. Contextual details of a user based on a mobile device can be used for authentication based on possession of a device. Password-less authentication of a user may be enabled by registration of devices and/or a location (e.g., a geographic location) as trusted. Security data embedded with encrypted data can be sent to a first device for password-less authentication of a user at the device. A second device registered with the user can obtain the security data from the first device. The second device can decrypts the data and send the decrypted data to the access management system for verification to enable password-less authentication at the first device.
