# Write Federation Information node

Creates a persistent link between a remote IdP account and a local account in the SP, if none exists yet. If a transient link exists, it is persisted. Existing account links with different IdPs are not lost.

Use this node with the [SAML2 Authentication node](saml2.html), and ensure that the NameID Format is `persistent`.
