# Manage Smart Login

Smart Login allows Passwordless authentication to Identity as a Service. When enabled, a user who has logged in to their Windows desktop using the Entrust Identity Bluetooth Smart Credential Reader 3.0.1 can authenticate to their Identity as a Service account without the need to provide a username and password. This feature is available only for the Identity as a Service Admin Portal, User Portal, and OIDC or SAML applications integrated with the Identity as a Service account.

note

Smart Login is supported on Chrome, Internet Explorer, and Edge. FireFox is not supported.

[📄️User Principal Name mapping Users require a User Principal Name to use a Smart Credential for Smart Login. Smart credentials configured on IDaaS do not have a User Principal Name (UPN)value by default if the user does not have a value defined for User Principal Name system attribute.
