Domain restrictions for login - how is the syntax for adding more than 1 domain?

I have 2 domains I would like to authorize for email signup.

I could not find in the documentation to use a space, a comma, a semicolon or a colon.

Please clarify

I don’t want to experiment on a live app, so please help me out here.

@Peter

It’s a comma. I’ll make sure that’s documented for the future.
