Persist login when change domain

[jsilmarovi]

Hello.

I have a content portal with three domains point to it. The access can happens trought xpto.com.br, xpto.com and xptow.com.br.

When I log in on admin panel throught xpto.com and changes to xptow.com.br for example, I need to authenticate on xptow.com.br to use the panel.

Is there a way to keep logged in on admin even I change the domain on url?

You are in search for a Single Sign On (SSO) solution. You might want to check out this SAML SSO ProcessWire module. Or you might want to check out other PHP SSO of SAML solutions.

With PW this is only possible for subdomains.

$this->config->sessionCookieDomain = '.example.org';

This setting includes:

example.org
subdomain.example.org
