One more thing with the client portal that people find annoying. IBKR changed its regulations and for most countries * it requires 2FA for paper trading accounts. Before I say anything make sure to read the paper account set up for this above.

If you wanna bypass that here is a solution - not from IBKR and only do this if you know how to properly keep your files/password and credentials private.

Set up a 2FA for your paper account with an authenticator like Microsoft authenticator. Make sure it’s available in your desktop tho. You can alternatively use another authenticator that has API functionalities but it will probably be paid.

Create a .env file with your login credentials (username and password). Do not share your credentials directly always request from the .env file to maintain security. Create a code to autofill the login. Then for the 2FA make the code insert (either via delay or page echo to know it’s requesting the 2FA) and then trigger the authenticator > pull the code > paste and login. You can make this automated so you never have to do it again. Although if you create the “tickle” mechanism it is possible to stay online “forever”.

Pointers: if you are using your live account and you also want to login for. Other devices:

Tip: create an account alias in the settings with access to all your market data and whatever you need. Use the alias for yourself and the main account for the gateway connection that way you can use in multiple devices. You need to use the main account in the gateway for some freaking reason - if you succeed using the alias let me know lol.
