# Use IP-addresses to whitelist Zivver in identity provider or firewall

Is it possible to use IP addresses to whitelist Zivver in the identity provider (IdP) or firewall?

## Answer

No, it is not possible to use IP addresses to whitelist Zivver in an IdP or firewall.

When users log in with SSO on a laptop, mobile device, or workstation, the SAML request to the IdP uses the IP address of that device.
