Hi, I made a website in ignition web dev, and there are links to other ignition applications there (they are on different gateways).  
I want it so that once u are logged in the website, u will be automatically logged in the applications.

Can I do that? If so, how?

Use a common identity provider for all of them.

Ignition delegates authentication to standard OAuth or SAML identity providers, and provides its own built-in identity provider for convenience.

Configure all of your gateways to delegate to a common public identity provider. Do the same (non-trivial) in your own WebDev application. Then a browser session that has cookies for a particular provider can share that session with multiple websites (aka "single sign on").

(If you had followed the advice to implement in Perspective instead of Webdev, this would Just Work™. Sorry.)
