What ip addresses does 1Password use


we are using the 1Password SCIM bridge for user provisioning from our Azure AD. The bridge itself is installed in our AWS environment. There we have created a firewall rule to allow traffic on port 80/443 from "anywhere". We would like to change that to a specific ip range to be more secure.
What addresses is 1Password using?

    Hi @Jwo87! Welcome to the forum!

    Please see this documentation page:

    1Password ports and domains

    Does this help?

  • Hi @ag_ana

    Thank you for your quick response. That page does not really help in our case, I guess that is more related to the Client application. What we need is an ip range which is used for communication between 1Password => SCIM Bridge.

    @Jwo87 we do not maintain this list as it changes fairly regularly. Our security model does however ensure bi-directional authentication (the SCIM bridge cryptographically identifies the server as well) and so this at least partially solves what I think you're attempting to solve.

    The inbound requests however are coming from your identity provider, there are no inbound requests that come from 1Password, only outbound from bridge to 1Password.

    Please let me know if you have any other questions.
