Login into multiple sites

[wm-simon]

Have a multi-site and use the User:Login_Form tag. The users should login to multiple sites with this form. I've tried site="*" and site="site1|site2. I couldn't find something in the docs to this. Right now, the login works just for the current site. Perhaps it's not supported or there is another way. Can someone help with this?

Logging in would log you into all sites. The multisite feature doesn't separate them. Or at least, it isn't supposed to.

Are you using different domains?

[wm-simon]

Yes, I use different Domains. I have a site with secured content, where users can login. When they are logged in, the other sites should show secured content from the site, where they can login.

Ah, okay. You could try setting the session domain in your .env file.

SESSION_DOMAIN=defaultdomain.com

Then the sessions will be shared as if they were all on the same domain.

I can not login anymore, not in the cp and not at the frontend. I've cleared the cache, but without success.
This are my settings in the .env

APP_URL_WERBEAGENTUR="http://2023.domain1.test"
APP_URL_FOTOGRAFIE="http://2023.domain2.test"
APP_URL_ACCOUNT="http://2023.domain3.test"
SESSION_DOMAIN=2023.domain1.test

I've changed the SESSION_DOMAIN to the APP_URL_ACCOUNT. Now i can login with the APP_URL_ACCOUNT to the cp and the frontend. But the frontend on the first site (APP_URL_WERBEAGENTUR) does still not recognize the login.
